Episode Transcript

(NARRATOR)>> TODAY ON DETROIT MUSCLE, IT'S TIME TO TAKE THE CADILLAC CTSV FOR HER MAIDEN VOYAGE. THEN BUILD THE CHEVELLE'S A/C SYSTEM.

(TOMMY)>> LAST TIME YOU SAW OUR CADILLAC WE WERE INSTALLING OUR UPGRADED SIX LITER LS ALONG WITH SOME EXHAUST MODS. WELL OBVIOUSLY WE'RE NOT IN THE SHOP. WE TOOK US A LITTLE DETOUR CAUSE WE WANT TO SEE WHAT THOSE UPGRADES WE'VE BEEN WORKING ON, WELL WHAT THEY BOUGHT US.

(MARC)>> SO WE CAME HERE TO DBR HIGH PERFORMANCE IN SPRING HILL, TENNESSEE. AFTER YOU BUDDY.

(TOMMY)>> THANK YOU, I THINK.

(MARC)>> DBR IS A PREMIERE HIGH PERFORMANCE SHOP KNOWN FOR THEIR WORK WITH INSTALLING AND TUNING BIG POWER UPGRADES. WE'VE WORKED WITH THEM SEVERAL TIMES AND THEY WERE THE ONES THAT TUNED OUR 1,000 HORSEPOWER POWERSTOP ULTIMATE CHALLENGER. THIS TIME THEY'RE HOOKING UP OUR CADDY TO THEIR HUB DYNO AFTER DBR'S DAVID BRANSON TUNED IT.

(DAVID)>> THE CTSV IS AN AWESOME PLATFORM BECAUSE YOU GET A SEDAN WHERE YOU CAN PUT YOUR CAR SEATS IN IT, PICK UP GROCERIES, TAKE YOUR KIDS, TAKE THE DOG TO VET, WHATEVER IT IS, AND YOU CAN ALSO HAVE A GM VEIGHT POWERTRAIN THAT'S BASICALLY THE SAME THING IN THE CORVETTE.

(MARC)>> THIS IS DAVID WITH DBR. DAVID, DID THIS THING NEED A TUNE WITH ALL THAT STUFF THAT WE DID TO IT?

(DAVID)>> DEFINITELY, DEFINITELY NEEDS TO BE RECALIBRATED WITH THE STUFF YOU GUYS DID TO IT.

(MARC)>> OKAY NOW WE WENT WITH THE STOCK INJECTORS. THAT SHOULD BE FINE RIGHT? NOW WITH THESE PARTS IT SHOULD MAKE ABOUT 500 AT THE CRANK. WHAT DO YOU THINK THAT'LL TRANSLATE TO HERE ON THE CHASSIS DYNO?

(DAVID)>> I WOULD HAVE TO GUESS BETWEEN 80 AND 100 POWERTRAIN LOSS.

(MARC)>> SO 400 TO 420?

(DAVID)>> 400 TO 420ISH, YEAH, THAT'D BE MY GUESS.

(MARC)>> NOT BAD, LET'S SEE WHAT IT DOES.

(DAVID)>> OKAY! [ engine revving ]

(MARC)>> HEY, IT MADE A LITTLE MORE THAN WE THOUGHT. THAT'S ALMOST 440.

(DAVID)>> I'D SAY THAT'S MORE THAN 500 AT THE CRANK.

(MARC)>> YEAH.

(DAVID)>> I FEEL LIKE BASED ON THE UPGRADES THE CAR DID EXACTLY WHAT IT WAS SUPPOSED TO DO. I'D BE VERY PLEASED WITH THOSE NUMBERS.

(TOMMY)>> NOW AFTER GETTING OUR CADDY OFF THE DYNO IT MADE SOME PRETTY DECENT POWER, ESPECIALLY WHENEVER YOU FACTOR IN NO MORE WORK THAN WE DID. NOW WITH THE IDEA ON THIS OLD CAR WAS TO BUILD A FUN CAR TO DRIVE AND NOT BREAK THE BANK DOING IT, AND IF YOU'VE GOT A LITTLE BIT MORE CHANGE TO SPEND YOU CAN FLIP OVER TO THE SECOND GENS. NOW THESE THINGS COME FROM THE FACTORY WITH A SUPERCHARGER, AND THEY HAVE THE OPTIONS OF HAVING AN AUTOMATIC OR A MANUAL, AND YOU KNOW, THESE OLD CADILLACS HAVE A HUGE AMOUNT OF AFTERMARKET SUPPORT TO THEM. THIS PARTICULAR CAR HAS A TON OF BOLT ONS ON IT. IT MAKES 700 HORSE AND IT RUNS IN THE 10-50'S ON THE TRACK.

(MARC)>> BUT IF YOU WANT TO BE A BIG DOG AND YOU'VE GOT ENOUGH MONEY IN THE BANK, YOU COULD BUILD SOMETHING LIKE THIS. IT MAKES OVER 1,700 REAR WHEEL HORSEPOWER ON THE STOCK COMPUTER. SO YOU'VE GOT RACE CAR POWER, CADILLAC COMFORT.

[ engine revving ]

(TOMMY)>> IT MIGHT NOT HAVE 1,700 HORSEPOWER BUT OUR OLD CADDY STILL HAS PLENTY OF GIDDY UP AND GO.

[ engine revving ]

(TOMMY)>> YEAH!

(MARC)>> WELL THE CADILLAC TURNED OUT PRETTY GOOD. IT'S A LOT OF FUN TO DRIVE AND IT DOES HAUL THE MAIL.

(TOMMY)>> YEAH, IF YOU'RE MAKING 500, 600, 700 HORSE, YOU KNOW THAT'S A PRETTY QUICK CAR. PLUS IT'S A BLAST TO DRIVE OUT ON THE STREET.

(MARC)>> BUT YOU KNOW THIS IS THE FIRST CADILLAC WE'VE EVER BUILT ON THIS SHOW. I FEEL LIKE WE NEED TO DO SOMETHING TO GET INTO THE SPIRIT A LITTLE BIT.

(TOMMY)>> I KINDA KNOW WHAT YOU'RE TALKING ABOUT.

(TOMMY)>> I SAY PENNINGTON, I AM TOLD THAT THIS COACH THAT WE HAVE ACQUIRED MAY BE A TAD BIT ON THE PEPPY SIDE.

(MARC)>> THAT'S RIGHT GOVERNOR. SHE'LL RIP YOU HEAD RIGHT OFF YOUR NOGGIN.

(TOMMY)>> JOLLY GOOD! I SAY WE TAKE THIS AUTOMOBILE FOR A GOOD ROW, WHAT HAVE YOU, AND INSTEAD OF DOING DOUGHNUTS, WHICH ARE EVER SO BOROUS, WE'LL DO A FEW PUMPERNICKELS.

(MARC)>> RIGHT THEN GOVERNOR, HAVE A SEAT RIGHT HERE AND WE'LL BE ON OUR WAY THEN.

HERE WE GO THEN! [ engine revving ]

(TOMMY)>> VERY GOOD PENNINGTON, VERY GOOD!

(MARC)>> SHE'S A STICKY WICKET! [ tires screeching ]

(TOMMY)>> THAT'LL DO, OH NO! [ engine revving ]

(TOMMY)>> HEY GUYS WE WANT TO STOP A MINUTE AND TALK ABOUT A BEAD ROLLER. NOW YOU'LL RUN INTO SOME THAT HAVE DIFFERENT OPTIONS, KINDA LIKE DIFFERENT SIZE THROATS, VARIABLE SPEED MOTORS, AND HECK, SOME OF THEM DON'T EVEN HAVE A MOTOR. THEY'VE GOT A CRANK ON THEM, BUT THEY ALL PRETTY MUCH DO THE SAME THING. THE WAY THESE THINGS WORK IS YOU SIMPLY TAKE A PIECE OF METAL, SLIDE IT IN BETWEEN THE DYES. THE NEXT THING YOU WOULD DO IS CRANK DOWN ON THE HANDLE, WHICH SQUEEZES THE ROD TOGETHER AND PUTS PRESSURE ON THE METAL. DEPENDING ON YOUR DYES DETERMINES WHAT SHAPE IT'S GONNA MAKE. NOW THIS PARTICULAR DYE IS A FIVESIXTEENTHS ROUND BEAD, AND IT'S PRETTY MUCH THE SHAPE THAT EVERYONE THINKS OF WHENEVER IT COMES TO ROLLING BEADS. THEY HAVE THEM IN A WHOLE BUNCH OF DIFFERENT VARIOUS SIZES, KIND OF LIKE THIS BIG FIVEEIGHTHS, AND DEPENDING ON WHAT YOU'RE TRYING TO DO, WELL IT'S GONNA DICTATE WHICH ONE YOU NEED. NOW THE NEXT THING WE'RE GONNA TALK ABOUT IS WHAT'S CALLED A TRANSITION DYE. NOW AS YOU ROLL THE METAL THROUGH IT, YOU'LL NOTICE THAT IT'LL GIVE YOU A NICE, SMOOTH EDGE, AND THEN YOU'D HAVE WHAT'S CALLED A STEP DYE. AND WHENEVER YOU RUN IT IN THROUGH IT, IF YOU NOTICE, IT KIND OF LOOKS LIKE A STAIR STEP. NOW WE JUST SHOWED YOU THREE OR FOUR DIFFERENT DYES, BUT THEY MAKE TONS OF DIFFERENT ONES, AND OFTEN TIMES YOU CAN KIND OF MIX AND MATCH THEM ALL UP AND IT'LL GIVE YOU DIFFERENT EFFECTS, BUT ENOUGH'S ENOUGH FOR NOW. LET'S GO AHEAD RUN A PIECE OF METAL THROUGH AND TALK A LITTLE MORE ABOUT HOW THIS MACHINE WORKS. NOW OURS HAS A CRANK HERE THAT LOWERS AND RAISES THE TWO SHAFTS TOGETHER, AND WHAT THAT GIVES YOU THE OPTION TO DO IS INCREASE OR DECREASE THE AMOUNT OF PRESSURE YOU'RE APPLYING TO THE METAL. HAVING THIS ADJUSTABILITY ALSO ALLOWS YOU TO KIND OF START ANYWHERE IN THE MIDDLE OF THAT PANEL. IF YOU DIDN'T HAVE IT, WELL WITH THEM ALL THE WAY TOGETHER, YOU CAN ONLY START AT ONE END, AND THEN GO TO THE OTHER EDGE. TO GET STARTED WE'RE GONNA DO A BEAD FROM ONE END TO THE OTHER, AND WE'RE GONNA HAVE TO BACK THIS UP JUST A BIT BECAUSE WHERE IT WAS AT WAS TOO MUCH PRESSURE. THAT CAN GIVE YOU SOME PROBLEMS LATER. NOW TO SET YOUR PRESSURE YOU WANT TO BACK THIS THING OFF UNTIL THE METAL WILL JUST GO THROUGH. GIVE IT A COUPLE OF TURNS AND NOW YOU'RE READY TO GET STARTED.

YOU CAN GIVE IT ANOTHER FULL TURN AND RUN IT THROUGH AGAIN.

JUST FOR GRINS WE'RE GONNA GIVE IT ANOTHER HALF A TURN AND RUN IT THROUGH ONE MORE TIME.

NOW THAT TURNED OUT PRETTY NICE, AND THIS IS ONE OF THE MOST POPULAR AND SIMPLE THINGS YOU CAN DO WITH A MACHINE LIKE THIS, AND THERE'S A WHOLE LOT MORE TO SHOW YOU, BUT THAT'S GONNA HAVE TO BE NEXT TIME.

(NARRATOR)>> COMING UP, WE'LL KEEP IT COOL BY INSTALLING A/C INTO THE CHEVELLE.

(MARC)>> HEY EVERYBODY, WELCOME BACK. WE'RE GONNA SWITCH GEARS AND JUMP BACK ONTO A PROJECT THAT WE'VE BEEN WORKING ON FOR A WHILE, AND THAT IS OUR '72 CHEVELLE BARN FIND. NOW THIS THING HAS COME A LONG WAY FROM WHERE WE STARTED. THIS THING CAME OFF THE FRAME AND WE'VE PUT 1,000 HORSEPOWER ENGINE UNDER IT, NICE PAINT JOB, AND IT'S ALMOST READY TO HIT THE ROAD, BUT THERE ARE SOME THINGS THAT STILL NEED TO BE DONE, BUT SINCE YOU'VE SEEN IT LAST TIME WE'VE DONE A LOT. WE'VE TIDIED UP A BUNCH OF STUFF UNDER THE HOOD WITH BELTS, HOSES, AND WIRING. WE'VE ACTUALLY GOT THE INTERIOR PUT IN, AND WE'VE GOT IT UP IN THE AIR CHECKING EVERYTHING UNDERNEATH TO MAKE SURE IT'S TIGHT AND SAFE TO DRIVE, BUT THERE IS ONE THING MAJOR THAT WE STILL NEED TO DO, AND THAT IS THE A/C HOSES. SO WE'RE GONNA DO THOSE TODAY. WE'LL NOW ALL WE NEED TO DO IS CONNECT THE DOTS, AND WE'VE GOT ALL THESE HOSES HERE THAT CAME WITH OUR KIT, AND THEY COME LONG. THAT WAY YOU CAN JUST CUT THEM TO FIT YOUR APPLICATION PERFECTLY. THE KIT ALSO CAME WITH ALL THE FITTINGS THAT WE NEED, AND TYPICALLY THEY COME LIKE THIS. THIS GOLD AND SILVER COLOR, AND THAT'S FINE, BUT IF YOU WANT SOMETHING A LITTLE CLEANER YOU CAN GET THAT TOO. WE GOT THESE FROM RESTO MOD AIR, AND THEY'RE JUST LIKE THE GOLD AND SILVER ONES BUT YOU CAN ACTUALLY HIDE THEM A LOT BETTER, MAKE YOUR SYSTEM LOOK A LOT CLEANER. NOW THAT'S ALL FINE AND WELL EXCEPT WE'VE GOT TO ACTUALLY GET THESE ENDS CRIMPED ONTO THE HOSES, AND THAT'S WHERE A LOT OF GUYS AT HOME WILL DRAW THE LINE BECAUSE EITHER THEY DON'T KNOW HOW TO DO IT OR THEY DON'T HAVE THE RIGHT TOOLS, AND THAT'S WHERE THIS TOOL COMES IN THAT WE GOT FROM SUMMIT RACING. IT'S AN A/C HOSE CRIMP TOOL, AND IT COMES WITH THE CRIMPER AS WELL AS DIFFERENT SIZE DYES FOR THE DIFFERENT SIZES OF A/C HOSES. NOW THIS THING WILL SET YOU BACK A FEW HUNDRED BUCKS, BUT IT COULD SAVE YOU AT LEAST THAT MUCH MONEY JUST THE FIRST TIME YOU USE IT BECAUSE IF YOU TAKE YOUR CAR TO A SHOP TO HAVE THEM MAKE THE HOSES FOR YOU AND CHARGE THE SYSTEM IT COULD COST YOU UP TO ABOUT $1,000 BUCKS. NOW BEFORE WE JUST START CUTTING AND CRIMPING WE WANT TO DO SOME MOCK UP FIRST, AND THERE'S A COUPLE OF REASONS FOR THAT. WE WANT TO MAKE SURE THAT THE HOSES ARE THE EXACT LENGTH THAT WE WANT. THAT WAY IT LOOKS REALLY NICE. ANOTHER THING TOO IS WE'VE GOT THESE CHARGE PORTS THAT WE HAVE TO INTEGRATE INTO THE SYSTEM HERE. WE'VE GOT A HIGH PRESSURE AND A LOW PRESSURE, AND THAT'S WHAT WE NEED TO HOOK INTO TO CHARGE THE SYSTEM. SO WE HAVE TO MAKE SURE THOSE ARE EASILY ACCESSIBLE, AND IF THEY'RE ACCESSIBLE NOW THEY'RE GONNA BE ACCESSIBLE LATER. SO THAT'S ANOTHER REASON WHY WE WAITED UNTIL NOW TO INSTALL THESE HOSES. THE FIRST ONE WE'RE GONNA DO IS GOING TO BE THE SUCTION HOSE, WHICH ROUTES BETWEEN THE EVAPORATOR CORE AND THE COMPRESSOR. NOW WE COULD JUST PUT A HOSE STRAIGHT FROM THE COMPRESSOR HERE TO THE FIREWALL AND CONNECT THE DOTS, JUST LIKE THAT, BUT I'D LIKE IT A LITTLE CLEANER. SO I'VE ACTUALLY RUN THIS HOSE IN BEHIND THE FENDER HERE. I THINK IF WE PUT ANOTHER 90 ON HERE WE CAN JUST CONNECT THE DOTS HERE, BUT THAT'S GONNA TAKE A LITTLE MORE MOCK UP.

WITH OUR HOSE CUT TO LENGTH, WE'LL RECONNECT IT TO THE ENDS AND MAKE SOME CLOCKING MARKS ON THEM TO MAKE SURE WE CRIMP THEM TOGETHER IN THE SAME CONFIGURATION AS WE MOCKED THEM UP.

THEN WE CAN PULL IT ALL OUT AND GET OVER TO OUR CRIMPING TOOL.

THAT SUCTION HOSE IS AT NUMBER 10, SO WE'LL GET OUR NUMBER 10 DYES.

WITH OUR DYES IN PLACE, WE'LL INSERT THE HOSE INTO THE FITTING, BEING SURE TO MATCH UP OUR MARKS. THEN START CRIMPING IT DOWN.

AND THAT'S ALL IT TAKES TO MAKE AN A/C HOSE.

(NARRATOR)>> UP NEXT, INSTALLING THE HOSES AND CHARGING THE SYSTEM.

(MARC)>> HEY EVERYBODY, WELCOME BACK. WHILE YOU WERE GONE I GOT THE REST OF THE A/C HOSES CUT AND CRIMPED, AND I GOT THEM INSTALLED. ALL BUT THIS ONE SUCTION HOSE HERE, WHICH IS THE ONE YOU SAW ME CRIMP THE ENDS ON A LITTLE BIT EARLIER. I JUST NEED TO GET THIS THING FISHED BACK INTO PLACE. THEN WE CAN GET IT ATTACHED.

NOW UNLIKE A TYPICAL HOSE END THAT WE WOULD USE ON SAY A FUEL SYSTEM, THIS THING IS NOT TAPERED. IT'S ACTUALLY AN ORING TYPE FITTING. SO THE END OF THE FITTING GOES INTO THE EVAPORATOR CORE HERE, BUT THERE NEEDS TO BE AN ORING THAT KEEPS THAT SEALED. SO WE NEED TO PUT THAT ON FIRST. THERE ARE DIFFERENT ORINGS FOR DIFFERENT SIZED FITTINGS, AND THIS IS A NUMBER 10, AND YOU HAVE TO MAKE SURE YOU USE THE CORRECT ORING FOR THE FITTING. DON'T STRETCH IT OVER TO MAKE IT WORK. WITH THE ORING INSTALLED WE'LL GO AHEAD AND PUT SOME LUBRICANT ON HERE. THIS OIL ACTUALLY COMES WITH THE A/C KIT. IT'S JUST AN ESTER OIL. YOU WANT TO MAKE SURE YOU GET THE ORING LUBRICATED ALL THE WAY AROUND. WE'LL INSTALL IT, AND MAKE SURE THAT THE ORING DOESN'T GET PINCHED. MAKE SURE IT FITS RIGHT IN THERE PERFECTLY LIKE THAT.

THEN SNUG IT DOWN.

WELL WE'VE GOT THEM ALL TIGHT NOW. THE NEXT THING IS GONNA BE TO CHARGE THE SYSTEM, BUT I MENTIONED EARLIER THIS WAS THE SUCTION HOSE, AND THERE'S A FEW OTHER LINES THAT PLAY A ROLE IN THE A/C SYSTEM, AND DEPENDING ON THEIR LOCATION, WELL THEY HAVE A DIFFERENT JOB TO DO, AND IN CASE YOU DON'T KNOW HOW AN A/C SYSTEM WORKS CHECK THIS OUT. IT ALL STARTS WITH THE COMPRESSOR, WHICH IS DRIVEN BY THE BELT AND DRAWS IN THE REFRIGERANT THROUGH THE SUCTION LINE. IT THEN COMPRESSES THAT REFRIGERANT AND SENDS IT INTO THE DISCHARGE LINE, WHICH DUMPS INTO THE INLET ON THE CONDENSER. THE CONDENSER IS LIKE A SMALL RADIATOR. ITS JOB IS TO CONDENSE THAT HOT HIGH PRESSURE GAS INTO A LIQUID. IT DOES THIS BY COOLING THE REFRIGERANT DOWN VIA AMBIENT AIR PASSING OVER THE FINS AND TUBES. FROM THE CONDENSER THIS LIQUID REFRIGERANT COLLECTS IN THE DRYER, WHICH ALSO ACTS AS A FILTER FOR THE SYSTEM. FROM THERE THE REFRIGERANT TRAVELS THROUGH THE LIQUID LINE TO THE EXPANSION VALVE. THIS VALVE METERS THE AMOUNT OF REFRIGERANT THAT IS RELEASED INTO THE EVAPORATOR CORE. THIS IS WHERE THE MAGIC HAPPENS. AS THE REFRIGERANT BEGINS TO EXPAND FROM A LIQUID TO A GAS IT RAPIDLY COOLS. THE BLOWER MOTOR IN THE PASSENGER COMPARTMENT PUSHES AIR ACROSS THE TUBES AND FINS OF THE EVAPORATOR AND IS COOLED AS A RESULT. AT THIS POINT THE COOLED AIR IS BLOWN THROUGH YOUR VENTS AND INTO YOUR INTERIOR. WELL HOPEFULLY THAT GOT YOU UP TO SPEED ON THE BASICS ON HOW AN A/C SYSTEM WORKS. NOW WE'VE GOT OUR SYSTEM ALL SEALED UP, AND ALL OUR HOSES ARE TIGHT, AND WE NEED TO GET SOME REFRIGERANT IN THERE. WE'VE GOT SOME R-134A HERE BUT BEFORE WE CAN DO THAT WE NEED TO GET ALL OF THE AIR THAT'S TRAPPED IN THE SYSTEM OUT, AS WELL AS ANY MOISTURE THAT MAY BE IN THERE AS WELL, WHICH WE'RE GONNA DO WITH THIS VACUUM PUMP HERE, BUT IN ORDER TO TAP INTO THE SYSTEM WE'RE ACTUALLY GONNA USE THIS A/C MANIFOLD GAUGE SET. WE'LL GET THE HIGH AND LOW SIDE HOSES CONNECTED TO OUR SYSTEM. THEN GET OUR VACUUM PUMP HOOKED UP AS WELL.

ONCE WE CRACK OPEN THE VALVE THE PUMP WILL PULL A VACUUM ON THE AIR CONDITIONING SYSTEM.

(MARC)>> WELCOME BACK. BEFORE THE BREAK WE HOOKED UP A VACUUM PUMP TO OUR CHEVELLE'S A/C SYSTEM SO THAT WE CAN GET THE AIR REMOVED FROM IT.

WELL NOW WE'VE GOT OUR VACUUM PULLED. THE LOW SIDE GAUGE STOPPED MOVING. SO WE KNOW THAT IT'S REACHED MAXIMUM VACUUM FOR THIS PUMP, AND I WENT AHEAD AND TURNED THE PUMP OFF, AND I CLOSE THE VALVES BECAUSE I WANTED TO ISOLATE OUR SYSTEM. THIS IS REALLY IMPORTANT BECAUSE I DON'T WANT TO WASTE MY TIME SPENDING 45 MINUTES TO VACUUM THIS THING DOWN IF THERE'S GONNA BE A LEAK. SO THIS IS A REALLY GOOD WAY TO CHECK FOR A LEAK. NOW I'M JUST GONNA WATCH THIS GAUGE FOR A COUPLE OF MINUTES TO SEE IF IT MOVES AT ALL. IF IT START LOSING VACUUM, THEN I KNOW I NEED TO STOP AND GO BACK AND SEE IF THERE'S A FITTING THAT'S NOT TIGHT OR SOMETHING ELSE WRONG WITH THE SYSTEM. WELL WE'VE LET THIS SIT FOR JUST A FEW MINUTES HERE AND THE GAUGE HASN'T MOVED AT ALL. SO WE'RE JUST GONNA HOOK IT BACK UP AND VACUUM IT DOWN FOR ABOUT 45 MINUTES. [ air hissing ]

(TOMMY)>> WHILE HE'S BUSY WORKING ON THAT I'M GONNA START REVIVING A COUPLE OF THESE TAILLIGHT LENSES FOR OUR CHEVELLE. NOW THE FIRST STEP TO DOING THIS, WE'D HAVE TO GET THEM CLEAN, BUT I'VE DONE THAT. SO WE CAN MOVE ON TO BUFF IT. WHAT'S GONNA BE DOING THE MAJORITY OF THE EFFORT IS THIS LITTLE WOOL BUFFING PAD HERE. NOW YOU CAN USE A FOAM, BUT I PREFER THIS ONE HERE. THE REASON IS WHENEVER YOU GO TO POLISHING THESE STRANDS HERE ON THE SIDE, WILL REACH INTO THOSE CORNERS. NOW THERE'S SEVERAL DIFFERENT COMPOUNDS OUT THERE YOU CAN USE BUT IF ANY OF THEM SAY IT'LL TAKE OUT 1,000 OR COURSER GRIT SCRATCHES YOU'RE IN PRETTY GOOD SHAPE. A LITTLE DAB OF COMPOUND WILL DO IT, AND WE'LL SPREAD IT AROUND A BIT. THEN START BUFFING. JUST RUN AT LOW SPEEDS AND KEEP IT MOVING SO YOU DON'T GENERATE A BUNCH OF HEAT. THEN WE'LL CLEAN IT UP. SHE LOOKS LIKE NEW. IT'S AMAZING HOW MUCH BETTER THIS ONE LOOKS AS OPPOSED TO THAT OLD DINGY ONE. IT DIDN'T TAKE A WHOLE LOT OF EFFORT. JUST A LITTLE BIT OF COMPOUND AND SOME TIME AND YOU CAN DO THIS AT HOME.

(MARC)>> WELL WE'VE LET IT VACUUM DOWN FOR ABOUT AN HOUR NOW, WHICH IS GOOD. 45 MINUTES IS ACTUALLY ENOUGH BUT A LITTLE BIT OF EXTRA DOESN'T HURT. SO NOW WE'VE GOT THE SYSTEM ALL CLEARED OUT. IT'S UNDER VACUUM. SO THERE'S NO MOISTURE AND NOW AIR IN THERE AS WELL. SO NOW WE JUST NEED TO GET OUR REFRIGERANT IN. WE'RE GONNA DO THAT BY DISCONNECTING THIS HOSE, AND ATTACHING IT TO THE CAM. WE'VE GOT THIS SPECIAL FITTING THAT PUNCTURES THE TOP OF THE CAN ONCE YOU SCREW THIS TAP DOWN, AND WITH THAT DONE WE CAN HOOK IT UP TO THE LINES RUNNING TO THE A/C. WE'LL OPEN THE VALVES TO LET THE REFRIGERANT INTO THE SYSTEM AND LET IT EMPTY THIS CAN. OUR SETUP WILL REQUIRE A COUPLE OF CANS. SO WE'LL SHUT THE VALVES AND SWAP THEM ONCE THE FIRST ONE IS EMPTY.

AND WITH THE VALVES OPENED BACK UP, WE'LL GET IT UP TO ABOUT 57 POUNDS AND CALL IT GOOD. WELL THAT'S ALL THERE IS TO IT. THIS SYSTEM CALLS FOR 24 OUNCES, WHICH IS TWO 12 OUNCE CANS. SO WE PUT THAT IN. NOW ALL THAT'S LEFT IS ONCE WE GET THE ENGINE FIRED UP WE CAN GET THAT COMPRESSOR MOVING, START BLOWING COLD AIR. IF YOU'VE EVER HAD TO FREE A RUSTY SEIZED BOLT THEN YOU KNOW A GOOD PENETRANT SPRAY CAN HELP YOU GET THAT JOB DONE WITH A LOT LESS HASSLE, AND THAT JUST GOT A LOT EASIER WITH LIQUID WRENCH PRO PENETRANT SPRAY AND LUBRICANT. THIS FAST ACTING ANTISEIZE FORMULA PENETRATES CORROSION, LOOSENS RUSTY BOLTS, AND DISPLACES MOISTURE WITH LONG LASTING LUBRICATION, AND THE FLASH SIGHT BUILT IN LED LET'S YOU SEE WHERE YOU SPRAY. THIS IS GREAT IF YOU'RE WORKING IN LOW LIGHT AREAS, LIKE UNDER YOUR CAR OR INSIDE THE ENGINE BAY. JUST LIGHT IT UP AND BUST IT LOOSE.

YOU KNOW WE SPEND A LOT OF TIME UNDER CARS IN HERE. SO HAVING A LIFT THAT IS BOTH CONVENIENT AND SAFE IS A BIG DEAL. OUR DANMAR D-10-ACX HAS A 10,000 POUND LIFTING CAPACITY, AND THE POSTS ARE ROTATED 30 DEGREES TO OFFSET THE VEHICLE POSITION, MAKING IT EASIER TO GET IN AND OUT OF THE CAR. THE DUAL HYDRAULIC CYLINDERS GIVE IT FAST LIFTING SPEED, AND THE BASE PLATES ARE OVERSIZED FOR MORE STABILITY, AND THIS LIFT ALSO COMES WITH A THREE YEAR WARRANTY. SO IF YOU'RE IN THE MARKET FOR A LIFT, TAKE A LOOK AT THIS ONE FROM DANMAR. WELL THAT'S ALL THE TIME WE HAVE FOR TODAY FOLKS. SO UNTIL NEXT TIME CHECK OUT MORE TECH AT POWERNATION TV DOT COM.
