Is this a parallel flow condenser

bob234 on Sun September 19, 2010 1:56 AM User is offline

Even though I am still using R12 in my S10 I want to upgrade to a parallel flow condensor. Having it warm up to 50 degrees at idle is unacceptable with the original tube and fin one. When I drive it blows 35 degrees, so the condenser is the bottleneck. Is this a parallel flow model? They claim it is a direct drop in, but don't state what type it is.

Don't know...

You could always add 1 or more pusher fans....

How would you mount one of those pusher fans in, and how would I wire it up. A lot of people use the switch on the back of the compressor, but mine doesn't have one. Just a shipping plug where one can go.

It's a piccolo condenser. Fords version for a R134a condenser.

A switch can be added to the plug in your compressor.
My first suggestion would be to test the fan clutch or simply replace. Average life is 3 yrs or 50k miles. The conditions described could be contributed to excessive fan clutch slippage. Why go to the cost of a new condenser if the fan clutch would eliminate your problem. The electric fans may offer a constant flow of air and thus aid in reduction of vent temps at idle, however, another factor comes into play.....the rotation speed of the compressor at idle. As the engine slows...the compressor slows also....and thus a reduction of performance. Is it possible that the compressor was changed at some point and the incorrect unit installer. Possibly one with a large clutch, this would also reduce compressor performance at idle.
Also check charge levels....most important.

Kid had an S-10 all black SUV, an R-4 compressor and with manual specifications of low side pressures shooting skyward towards 60 psi as being normal. Cleaned up all the debris in the radiator, condenser, in between, repaired the shroud, installed a new OE fan clutch, still was a beast to drive in on a 95*F day. Solution for my kid was to use my car on days like that. Didn't try a parallel flow compressor, assume since yours is stock and R-12, has to be at least 16 years old. These things never did cool worth a darn, GM did make improvements with the 96 model. Even to go as far as you could ride in one without breaking your back.

You don't get much cooling with a 60 psi standard low side pressure, I used his on hot days, but I am tough when I had to haul stuff, just rolled down the window. Adding a second condenser fan may even block airflow. Parallel flow may help, but have no record of this. Could try it and let others know from your experience.
