Retrofit for 1976 F100 w/1977 400 engine

JeremyB on Thu June 18, 2009 5:09 PM User is offline

Year: 1976
Make: Ford
Model: F100
Engine Size: 400
Refrigerant Type: R134a
Country of Origin: United States

My friend bought a 1976 F100 recently. Turns out is has a 1977 400 engine in it. Previous owner had put on a conversion sticker (not filled out) and conversion fittings, but no refrigerant was put in.

My questions are:

How much oil does the York compressor take?
Is POE okay?
What is the factory charge of R12?

You can use a quality ester like BVA auto 100, I believe the crankcase holds about 10 ounces.. As far as R12, you might have to wait until someone with an older book comes along...Or fill by the pressure/feel method.. I know they held a few pounds back then...

The York carries all the oil in the sump, correct?

Does that mean I can just replace the receiver drier without flushing? I assume there will be little to no oil outside of the compressor...


Anybody had time to look up the refrigerant capacity?

I show a oil capacity of 12oz for the compressor. As far as R12 charge, couldn't find.

My 'older' book only goes back to 1980, when the 'F' series held 3.50 lbs. That dropped to 3.25 lbs in 1982.
Maybe start at 3.00 lbs then add an ounce at a time.

Looks like the 1980 F100 only shares a compressor with the 1976/77 model year. But 3.5 lbs is closer than no guess at all!
