Re: low side low, high side high, compressor cycling

Mist your condenser with water when it is running and let us know what the high side does.

Re: Adding electric fans to antique car

Look at the fan controllers from DC Controls. They vary the fan speed based on need, and they can be commanded easily from the A/C circuit.

Re: Saga with my 87 Chevy Truck continues

Test the pressures at full load Doors open, cabin fan on highest speed. Raise the engine rpm to 1800+ RPM, and hold it there for one minute. While the engine speed is above 1800, record the high and low side pressures. Post the pressures and the ambient temperature. Those were the conditions for th...

Re: Saga with my 87 Chevy Truck continues

Well I finally got the time to finish everything up and get it charged this weekend. Factory R12 charge is 52 ounces. It vacuumed down nicely and all was good. I pushed in the first can as liquid with the system off and into the high side port. Started charging it up and interior temps were steadily...

Serp to parallel condenser affect on capacity

In switching to R134, I upgraded the serpentine condenser to a parallel (and I'll be swapping to a parallel in my XJ also). I'm wondering how this affects the overall volume of the system. I think it will throw the 80% rule out the window on the R12>R134 conversion. So then do I just charge by press...

Re: AC Pressure readings are high [PICS]

The electric cooling fans on those do go bad. Make sure the electric fan is good and that the mechanical fan clutch is in good shape.

Re: Saga with my 87 Chevy Truck continues

Any thoughts on how converting to this condenser - http://www.ackits.com/index.php?route=product/product&product_id=46963&search=CN+3642PFC Is going to affect overall system capacity? I think this throws the whole "80% rule" out the window on the 134a capacity. So charge by pressur...

Re: Saga with my 87 Chevy Truck continues

Lesson learned - just contact Tim and get all of your parts through him. Going through other suppliers for some of the parts netted me some crap parts that are being sent back and I'm having ACKits expedite new parts to me.

Re: Saga with my 87 Chevy Truck continues

Cant anything be easy? The GM factory replacement condenser is about 2" smaller than the original and doesn't fit into the mounts. Ugh. No part number on the condenser so I am wondering if it is the correct part? Supposed to be a parallel flow that replaces the original. It is smaller overall a...
