It got a little warm today in southern New Mexico so today was the first day I drove the 3sgte swapped Celica in stop and go traffic with the AC on. Normally without the AC on, the engine temps bounce between 189 and 199 degrees F. When I turned the AC on it climbed to 209 degrees in the course of 5 minutes before I turned the AC off. Once I turned the AC off the temp quickly dropped back into the normal range in about another 2-3 minutes. I am reading the temps off an aftermarket water temp gauge with the sensor on the upper radiator hose. Below is a picture of the type of gauge I am using. It is a Glowshift MaxTow water temp gauge.
When that gauge reads 215 degrees the stock dummy temp gauge in the car starts moving towards the H. I am running an Ebay 2-row radiator with aftermarket fans and I have a FMIC. Should I keep the aftermarket fans or go back to a stock radiator with stock fans? Also, the Ebay radiator is pretty dirty from constantly taking it in and out of the car during the build process, could that be the culprit? Is there something else I should check on that may be causing the engine temps to climb with he AC on? Below is a picture of the 2 different radiators. Is there really an advantage to running a 2 row radiator with a 3sgte? This post has been edited by HardHead93: Mar 17, 2017 - 7:33 PM |

That's great it's working so well. IAT controlled fan shouldn't be too hard, can probably do that with a simple radiator fan controller kit if you want it sooner than later I suppose.

I have the intercooler fan on a kit that turns on the intercooler fan when engine coolant temps reach 200 and turn off at 185. The lowest temp kit I could find was 150 degrees which is still to high for me to put it into the intake. That is why I am planning on wiring it into the standalone ECU. Megaquirt has a function where you can have a circuit turn on/off when certain user defined conditions are met. Do you know of where I can get an IAT switch that is rated for 100 degrees because that would be idea of when the fan should turn on? If not the standalone is my only option.
