Overheating problem. Any suggestions?

Always read the forums, have learned so much just by searching and reading. I have an overheating problem with my Prelude 98. Fans wont come on when car reaches normal running temperature, both fans come on when I turn on the AC, but not automatically. After doing some research I was sure it was the Radiator Fan Switch the one on the thermostat housing, I replaced it but car still overheats after 20 minutes of driving, fans wont come on. I also did the paperclip trick on the Radiator Fan Switch connector and both fans came on when I turned the key. Any suggestions? I have also replaced the Radiator and thermostat, no coolant leaks whatsoever, water pump not leaking and the head gasket I believe it is ok I dont see any white smoke coming out. Thanks.

i've never looked at the cooling system much but i'm GUESSING it's a bad wire somewhere...if you know the switch is working then it has to be messing up something in the wiring...trace your wires and check for broken or worn ones....not sure if there is a relay for the fan can't say for sure but i assume there is so i'd check it. good luck

Bleed the cooling system and add the proper coolant mix. ( I doubt thats the prob though but it can be) How long ago did you replace the radiator? Does it over heat with the AC on and off?

Do what I did and upgrade your cooling system.

Re: Overheating problem. Any suggestions?

yeah if its over heating while your driving atleast over 25mph then that can omit your fans. not syaing thats an issue but just saying thats not the main culprit of why your over heating. like one of the previous post said make sure your collant is the proper mixture or atleast not old, make sure its at the proper level. and then you can go from there. key thing at this point id deffinitly bleed your system more... if you want take the radiator cap off (when cold). make sure your heat to your car is on and full blast this ensures all your heater core hose are also getting used in this process to remove any bubbles in their lines. when the gauge reachs half way i tend to like to pulsate the throttle around 3 times to 3000 rpm to help preasurize the system to knock any airbubbles loose trapped inside the motor and i do this around 4 seperate times with around 30 second intervals. basically...(so hit the throttle 3 times @ 3000rpm...wait 30 seconds, then repeat 3 more times in the same order) and then once this is done let it idle for a bit more and theen turn it off put the cap back on and test it with the cap on at idle with the air on or off your choice (btw your normal operating temp is around 195*F factory fan sensors tend to kick in at 207-212*F since the boiling point of water is 215* hope alll this helps man. and i believe your car will endicate its overheating once it passes 215*F (do not know for certain)
