Based on what you are saying and what you have done so far you have a cylinder head gasket leaking combustion gases into the cooling system, this type of leak causes a gas bubble to form around the thermostat and then it will not work properly. Also when this type of leak is the problem there will be no white smoke out the tailpipe or coolant in the oil, the gasket only leaks on the compression stroke.

Testimonial: "Dennis Wei, thanks for the help on my 94 Acura, your description with the gasket leaking on the compression stroke was right on the money"

1998 Dodge 3.3ltr grand caravan overheats.I have repaced water pump,Thermostat,Had cracked head and replaced both of them with new ones,Replaces fans,replaced fan relay,All hoses,Radiator.When i start...

You would need to figure out if it is a cooling problem or something producing extra heat in the engine.
Is the radiator fan pulling enough air thru the condenser and radiator ?
Is the fan coming on and also when the ac is on and when the engine reaches 220 degrees ?
Is it possible the exhaust has a restriction somewhere ?

Thermo valve broken, does this cause over heating?

if you mean "thermostat" valve .. then that can fail either open or closed . if it fails open then the engine will not reach normal operating temperatures .. if it fails closed then yes the engine will overheat .. another common failure is the radiator fan .. it only runs when the car is not moving .. as long as the car is moving then cooling air is available so the fan is not needed ... so if your car does not overheat when driven but overheats when stopped or idling then suspect the radiator fan or thermal switch (mounted on the radiator) .. that switch turns on the fan when the radiator gets so hot ... you can just listen for the fan when hot .. you should hear it .. .. if your car gets too hot while driving then suspect a bad thermostat or clogged radiator .. sometimes a bad water pump (broken implellers) will cause the trouble ..

The radiator cooling fan is not working. Upon

assuming fuse and relay are fan should be running when the engine is cool/cold, the only time the fan should be running when it reach over operation temperature which then the fan kick on to bring the temperature back down to it operation temperature. both fan work in sync with one another, addition cooling is needed when the ac is running. when the last time have you replace thermostat and Thermos sensor/switch. I would replace both unit if you have not done so. The thermos/switch will turn the fan on when it reach certain temperature and cut off when it sense the temperature drop in the engine.

Overheating 93 sl1

The cooling fan circuit is composed of basically 3 components. The fan, fan relay, and a cooling fan switch. If you are sure the relay and fan are ok, it is probably the switch. It is located on the top of the engine block very near the upper radiator hose connector, close to the thermostat housing. A car parts store can tell you where it is located. NOTE: There is more than 1. If you have a temp. guage, there is a sender that operates the guage. Also, there is 1 that sends information to the computer. So, make sure you ask for the cooling fan switch when you talk to the parts store people.

96 Acura RL overheating.

have you changed the thermostat? located at upper hose opposite radiator end in the gooseneck (usually 2 screws) make sure you buy a gasket or gasket making compound if changing. most overheats occur due to stuck thermostat (doesn't open to cool) you could pull tstat out for temp fix but it wouldn't heat well in colder weather

What causes a 97 acura 3.2 tl to over heat

Many possibilities. 1st check coolant level when cold, make sure it's at the proper level, and a 50/50 mix (half water half coolant). Is the engine temp getting too high, or is it actually 'boiling over' with evidence of steam and coolant loss? Don't drive it when the engine temp gets too high, you can cause other serious problems. When the temp gauge starts to climb, check under the hood and see if the cooling fan is going on. It's possible the fan is not operating due to sensor or switch failure (they signal the fan to go on and off as required), or it can be a fan motor that's shot, a thermostat that is not opening properly, a radiator plugged up with rust and corrosion from neglecting cooling system maintenance. So as you can see, there are many reasons for your car to overheat. Answer my questions above, and I'll try to help you pinpoint the cause.

Truck overheat after thermostat was replaced. Blows cold heat too

The radiator is probably damaged have your system pressure checked for leaks make sure you fan relays are working and fan motor.

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

My 94 mazda 323 is boiling in the overflow tank. i have a ajustable thermate state that fix the promblem last time but now its doin it again. check by racq and they said that my fan is not kicking in.

I have had a similar problem.Check all of your Radiator and Heater hoses for leaks. The cooling system doesn't need to lose much coolant to create overheating problems. If you find no leaks -check that your bottom radiator hose isn't sucking flat and restricting coolant flow.
