overheating
« on: June 14, 2014 - 09:11:34 PM »
For those of us that live in a hot climate and need A/C.

Did some bench racing with some friends and the topic was over heating. One of the guys once had a GM car with AC that got really hot in stop and go traffic. He tried the usual with alu rad, fans, shrouds etc, got better but not good. Finally, he removed the AC condenser (sat in front of the rad) and hung it under the car (under pass seat). Left a gap of 1.5 inch between floor and cond, installed a 10" electr fan to cool it. Problem solved, did not over heat.

Back home I got under my cars and there is not much space on an e-body with unit body. It's doable but 10 feet away from the car, it will be visible. Got under my Pontiac and with a frame, there is plenty of space.

Our cars had from the factory the cond in fr of the rad so I think his problem was related to something else.
But it's an interesting thought as it apparently helped.

What do you say, anyone tried this?

Doubtfull GM would make a car that when at idle, it would overheat, with A/C on.
Could have been something as simple as the radiator fan was not coming on
when needed, due to a bad temp sensor.

even spacing the condenser further forward & adding a front spoiler to bring more air into the rad would help . I have moved trans coolers under the car never a condenser though

Agree on spacing, my A/C - radiator guy says you should have an inch between rad and cond.
Here we add an electric pusher fan in front of the cond, nice with cool air when sitting by the redlight.

Don't think the spoiler would help when you are standing still?
