have a ? concerning recharging the A/C system on my 97 Sport V6. I have a Haynes manual which shows where the low pressure port should be (on top of the compressor) but I don't have a port located there...there is one, however, on the side of the piping on the compressor, but that is going to be high pressure line, which I can't use to recharge the A/C. Am I missing something or is there another location to recharge it using the low pressure side? Thanks in advance for your help

It's on the silver line...not the compressor. Make sure you warm up the R134a bottle as well (hot water in a bucket works great). (Don't just keep adding refrigerant either...you can blow up a system that way.)

Was this system discharged? If so, you'll need to pull a vacuum on it first to clean up the system.

Bernd is correct, you should locate the low side service port on the silver line running to the condenser. I recently charged my 97 and ended up with a final high side pressure reading of 325 psi at an ambient temp of 91 degrees F. running the engine at 1500rpm's, this gave me a duct temp of 42 degrees F. If you keep your high side at 350 psi or below, you shouldn't have to worry about blowing anything. Do take Bernds advice, and draw the system into a vacuum at least once (I prefer to do it three times aka a triple evac) if the system was opened, this boils out any moisture in the system and will give you a much cooler duct temp. Hope this helps. XLR8 2 60

josh to vacuum out the system you need a multi hundred if not thousand dollar system to do it, you can do it your self, but the only way the dealers of such systems will sell you one is for you to show them your EPA certificate first, that requires several months of schooling and a rather expensive fee for the test you need to pass and of course, more money. Its mostly one of those things you farm out to a pro cause it just costs too much otherwise.

You need to be certified in Wisconsin just to
buy the refrigerant.

However I can drive 35 miles in to Michigan and buy
it over the counter at the parts store.

All you need is a vac pump to evac the system
and add it to the low side to specs, I have all
the equip but no one in the shop is even
interested in getting certified.

Such a deal
