Overheating

[vmchurch]

its my buds 95 EX.....the car runs fine except the coolant is boiling and the car overheats. The temp gauge shows no overheating as far as i know. The water pump is brand new, so is the timing belt and the timing is correct. He just replaced the timing belt for the first time (at 170k miles ). Lemme know what you guys think, i think its either the coolant temp sensor, thermostat or radiator.

How do you know the car is overheating....If the temp gauge aint reading hot then its still normal. Or are you saying your temp gauge dont work. Coolant is suppose to be hot and whatnot sinces its liquid under pressure traveling in an engine that is running around 220F or whatever.

turned out to be the thermostat so far, its not completely fixed but that took care of most of it. The coolant is actually boiling in the resevior, thats what i mean by overheating.....and the fans aren't coming on at all.

Ahh ok the reservoir is a diff story. Id check cap also and a t-stat would cause that too. Do both of your fans turn on when you turn on the A/C? If they do that excludes the fans.

[vmchurch]

ok, fans work properly....except that they don't come on when the car is hot. The t-stat was replaced and the coolant doesn't boil anymore. The fans still don't come on tho......maybe the coolant temp sensor?

its also posible you might have some air in the system, if nothing else run the car with the ratior cap off, and add coolant as needed, it should buble out the top a little bit. that should take care of that if thats the problem.
good luck!

i had this same problem except my fan relays were bad(located on the inside wall of the drivers side quarter panel) i replaced both including my t stat and it runs fine ever since, excpet latley its running a little hot but it is getting hot where im at but i think its just time for a system flush.

Use BBQ paint on the whole engine. it's rated for 1500 degrees.
