s13 sr20det overheating on hot days???

[nismo_drifter]

okay so is this normal for my car to be overheating on 95 to 100+ degree weather???

i have a sr with nismo thermo, mishimoto rad with mishimoto dual 12in fans, front mount intercooler for the cooling system...the fans are wired to come on as soon as i turn the car on and they are in the engine bay blowing towards the fire wall...



the car idels and drives fine...on cool days i can drive it as long and far as i want with no issue of it over heating, but when it is hot out if i dont turn the heater on blast then after like 30-40mins of driving it will start to slowly over then i turn on the heat on full blast then the temp will go right back to normal but if i turn it off after that then will still do the same thing???what is going on with my car???does it need more cooling like oil cooler???


there is no air bubbles in my system and the water level never changes???



the car is still running stock turbo manifold and turbo...the motor is all stock...need help cause i need to drive my car in this hot weather...thank in advance....

What is the content of your radiator? 50/50 Coolant/Water? Tap water? Distilled? Might need to get different fans (Altima or Taurus) to see if it makes any difference. I'm in Orlando, FL and it reaches 100 degrees all the time and I've never had an overheating issue.

I've got 75% distilled water, 25% coolant, w/ Altima fans from a 1997 Altima.

1 full bottle of 100% coolant and the rest is topped off with hose water...

Drain it, run water wetter, some 25% coolant, 75% water...if that doesnt help, stick back the stock clutch fan. If that still doesnt cool it enough, I'd pop that thermo out and drill holes into it.

I see your problem, your running dinky little 12 inch fans...

Im running flexalites on a koyo and it overheats like a bitch when sliding and will get there after I beat on it on the highway.

You need a shroud. Taurus or Altima fan will do the trick, im in the process of picking some up.
