Tee it into your vacuum pump- anything below 500 microns is excellent--but it all depends on your vacuum pump's ability to pull a good vacuum- you can always deadhead the micron gauge directly into the vacuum pump to test the pump only- and its ability to pull a good vacuum- some vacuum pumps are wo...

V-7s and V-5 need to be mounted with control valve at 6 o'clock or near that-- 5 to 7 o'clock will work-- it is for oil splash inside the crankcase. A V-5 will do as good as the V-7 in my opinion. I have seen too many V-7s run low on charge and burn up inside on the S truck application-- I usually r...

Your OEM accumulator has the oil part number on the label- google it and see specifications. The oil won't go in the discharge hole of the compressor (the small one) there is not enough room in that cavity-- but it will all go in the suction port- the larger port (and pipe) there should be an "...

If the condenser s doing its job the temp should drop from inlet to outlet-- thus "condensing" occurs-- that is why it is set up to have air blown across it- to cool the refrigerant inside that allows it to change state- from a gas to liquid....if there were no cooling- there would be hot ...

A new service compressor uses 134a port configuration- which needs to be adapted back to r-12 hose manifold as is yours...so you use the sealing washers in your kit- never use the aluminum port locators-(metal stubs you called them) (sleeves) in the kit- I have been doing a/c for 25 yrs and have nev...

I hope you pull adequate vacuum first--and you always charge by weight- not pressures in automotive a/c....so don't ask for pressure specs- there are none...just opinions

One can is 12 ounces- your truck holds 2 lb or 32 ounces- so you need almost 3 cans. You have trouble getting the first can all in because it is almost empty- put another can on, then another and be happy. The compressor will suck refrigerant in and stop cycling so rapidly when you get enough "...

There is NO low pressure switch on your 1998 vehicle!!!! Low pressure switches stopped on "C/H" cars in 1996! which used an HD-6 compressor. 1996+ MY "C/H" cars utilizes a V-5 variable stroke compressor- that averts evaporator freeze-up by destroking the displacement. You have a ...

Every scroll I have run or seen on current vehicles have a need for speed- every one of their owners complain of no cooling at idle. Suction pressure is in the 60s at idle- will drop to 30s at 3500 erpm.

Did you know that at the assembly plant that the entire system oil charge- 9 ozs was in the belly of the compressor upon compressor install and was pumped out of the compressor at engine start-up??? So now you are worried about where to put it?? Don't be. Every compressor ever installed on any car h...
