I know there's an HVAC forum... but its pretty dead. I'm hoping to tackle my AC problem tonight...

Here goes:

'97 F-150; 4.6 V8; 105,000 miles

putting a new comprssor in my truck... old one leaked from front seal.

The new compressor says to measure the amt of oil from the old comprssor and add that much back into the new one... but if the old one is leaking then how much oil do I need?

Do I add the oil directly to the compressor or add it in wth the freon?

Also... trying to save some cash. Called ford and they said the compressor on my truck is the same as on the mustang... only the clutch is a diff part number. the mustang part was cheaper so i got the mustang one (saved $60 at autozone)

the mustang compressor came with a clutch... the clutch _LOOKS_ diff from the one in my truck but has the same size pulley and electrical connection... any harm in using the mustang clutch on the truck?


thanks,
Sal

 

I can't help you with the clutch thing but I put the oil in the inlet side of the compressor before I put the compressor in. I also put about 1/2 ounce more oil than I measured out, just in case. I don't honestly know if there is anything wrong with doing it that way but, everything is working fine and I have plenty of cold air now.

All the freon they sell at the store has oil in it... so if i add 4 oz of oil directly to the compressor and three cans of freon w/ 2oz of oil each... won't that be too much oil?

Did the freon you bought not contain oil ?
