1991 Caprice 5.0l Parts

WyrTwister on Mon May 12, 2014 5:16 AM User is offlineView users profile

Year: 1991
Make: Chevy
Model: Caprice
Engine Size: 5.0l
Refrigerant Type: 134a
Country of Origin: United States

I am restoring this car , after it has set , out in the country , for 10 - 15 years . It belonged to my late Dad .

I may need a new condenser coil and the line from the condenser to the evaporator ( that contains the OT ) .

If I replace the condenser coil , I need a recommendation for a " better " coil for 134a retrofit .

Also , would like to avoid going to the Chevy dealership for the line .

Could not find the line on the ackits,com listing for this car . The condenser coil I found , do not know if it is standard for r12 or higher efficiency for r134a ?

God bless

You mean compressor coil?

The condenser coil that is located in front of the radiator .

Compressor coil , I would think of the electrical coil that activates the compressor clutch .

Keep it R-12. Thats what it was designed for and it cools better.

Only issue is R12 is becoming an issue now. Price a 30lbs cylinder today. $700.00 my cost. Ad a mark up to a customer and you're talking $ 200.00 in refrigerant to fill a car these days. Simple o-ring fails and it does no matter how hard one checks for leaks. A shop or person can be eating a high cost to replace.

I have never wanted to use an alternative, but it might be getting time to look at what might work in some cases.

R-12 is too expensive !

I may have to replace the condenser coil , any way . Appears to be one of my leaks . I thought , if I do , might look at a " better " coil ?

Another thought , how much improvement would an electric fan , in front of the coil , blowing through it & into the radiator ? It has a mechanical fan with the viscous fan clutch .

Suggestions as to how to cycle it ? 12 VDC relay driven by the voltage that cycles the compressor clutch ?

God bless

To change to 134-a you have to flush the system, replace the accumulator, replace the oil with 134-a compatible, install an HPCO and experiment with the amount of charge. Then it won't cool as well as R-12. When you consider the cost of these parts and the cost of your time to fiddle with all of this stuff, the cost of R-12 isn't so high. You said you were restoring this car, so why not restore it 100% and have a better cooling system ?
