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 |

A lot of people remove A/C as well, so they wouldn't have a problem in that regard. As far as the radiator goes after looking the generic eBay specials and the Mishimoto do look strikingly similar. Not saying it's the case but odds are they're both made by the same factory and the best ones get the Mishimoto branding while the others get sent to whatever seller on eBay or Amazon. It's hard to tell from the pictures, but it does seem like the Mishimoto ones have cleaner welds. If it were me I'd look into the Koyo Racing radiator part# R1958.

I didn't even think about that brand. It looks like the stock radiator fans mount directly to this radiator. The following thread says so: http://www.6gc.net/forums/index.php?showtopic=61443 Can you confirm if that is true because if that is the case, I will definitely go with that radiator? |
