This is going to be a fall/winter project along with a stack of others...
After this summers brutal ambient temps that would overwhelm my a/c condensor at idle in traffic and send the system to high pressure where it would cut out and leave me sweating until the lite turned green, I've decided to re-install a fan up front. This is going to have to be a face mount on the condensor since my oil cooler now rest where the Aux fan once lived.
What I want to do is install a fan big enough to cool the condensor when there is no or minimal air flow...like in traffic on a hot day. The sucker fan pulls plenty of air, around the condensor (by design) to the radiator. The system prioritizes the air flow when its limited.
I want to find some way of making this as automated as possible. Not waiting until 238 degrees like the factory aux switch will do. I am thinking about a lower temp switch to go in that same place, if available to turn the new fan on at 190-200...soon enough that it won;t let the a/c go to high pressure shut off.
IF such a low temp switch exist that will fit that hole in the driver side head.
OR
wire in a relay that would trigger the new fan whenever the a/c is turned on much like the main fan is set up to do... If I am thinking right all that needs is a fused power source then tap into the control ground that loops across the a/c switches for low press, cycling and high pressure so the ground path is completed tripping the relay and allowing the independent power source to run the new fan.
Last option would be a switch inside the cabin....although I already have a switch plate in the dash by the key, I'd rather not have to remember to use it...
Any thoughts?
If anyone does know of a temp switch that will fit the existing hole thats good for around 180-200 area, that would be great. I do not know if any other temp switch would fit...Like the CS switch in the front of the intake.
