Well, the winter seems to be over where I am and the temps are getting up to the upper 70's here. I am starting to see an old problem come up again and I am not sure what to do....
Basically to sum things up, I have a problem with my engine running up to 210 to 230 while driving normal just during the daytime. At night when things are cooler, I don't have this problem. The higher temp only happens when driving under 50mph which sounds like an air flow problem to me. At 60mph, the temp stays about 200 to 205. Before anyone starts saying to replace the radiator, water pump, thermostat, or radiator cap, I have already done all those in the last 6 months. Twice on water pump thinking that was my problem and I had gotten a defective one, 3 different t-stats (180, 192 "failsafe", and standard OEM 192 which I am running now), and replaced the cap 2 times thinking I also purchase a defective one. Last thing I replaced was the turbo with a brand new EVO III 16g thinking the water ports were messed up some how since the old one was going bad anyways.
During the day, I will not drive hard since the temp goes up really quickly after a 3 or 4 second WOT pull. I have a single slim fan from Autozone, which takes up the entire height of the radiator, that runs all the time when the ignition is on. It is located to the left of the turbo since the heat from the turbo would melt the plastic. I have also flushed the entire coolant system 2 times and replaced the coolant with a 50/50 mixture the first time and a 70/30 mixture the second time. I do have a FMIC which may block some of the air flow but I keep it clean and blown out of bugs or debris. I did not have the overheating problem when I first installed the FMIC....it was about a year later. The over heating actually started after I replaced my oil pump and bottom end bearings with ACL bearings. The car was down for about 3 months waiting for parts and time to work on it. I did clean out all water and oil ports with pipe cleaners as I have always done when rebuilding engines.
A couple questions....
Would installing a "pull" style radiator fan on the FMIC be any help?
Should I replace the "pull" style slim fan with a "push" style so I can mount the radiator fans on the other side of the radiator possible pushing cooler air through the radiator?
The radiator that is in the car is for an A/T which I do have, but I have an external transmission cooler. Would replacing the radiator with a M/T radiator make any difference?
Any help is greatly appreciated!
