Well, what you've already done should take care of most of the problems I can think of, but you could have a clogged hose somewhere, or you could be low on antifreeze. Also, if you have a damaged or aftermarket front grill, you may not be getting enough airflow, even with the fans. Also, something else you could check is your temperature sensor. It's possible that the sensor is bad, and is giving the computer false values, making you think the engine is overheating when it really isn't. That's really all I can think of, unless you live in the desert or something. You might just have to bight the bullet and have a mechanic look at it. I'm sure you're frustrated, so good luck. Also check the water pump a water pump not circulating will cause the car to build up heat and over heat. Check to see if the radiator is cold if it is and you have no heat that could very well be it. If those are the case and the coolant reservoir is hot that is a water pump. Also if you can squeeze the top hose and hear or see the coolant is filling up in the collant tank cause of that you know you don't have a clooged radiator normally. A water pump doesn't just have to leak to be bad. Also double check your tail pipe for buring of antifreeze smell it and check your oil level to make sure its not mixing.

have you flushed your radiator or changed the thermostat it could be stuck

Test gauge function with a mechanical gauge to get actual engine temp.

Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.

If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat

you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.

I have a promblem with that too, my car would overheat very fast, it was a faulty NEW thermostat. It still runs hot, I think I need a new water pump

hello Can you tell me why the heater on my 2002 toyota yaris isnt working? Ive changed the thermostat,flushed out the radiator and also the heater matrix behind the dashboard is getting red hot as well

cooling system needs flushed out and a new thermostat installed, also if the radiator is still original it probably needs replaced or rodded out.

bad thermostat, bad waterpump, plugged radiator, or the cooling system is filthy and needs flushed out.

I have the same issue. I have heard getting the radiator flushed might help. Otherwise look to the thermostat.

More than likely it needs a new thermostat and the radiator back flushed.

It could be one of many things.......radiator fans notworking/low on coolant/stuck thermostat/ radiator may need to be flushed......

Could be your electric fan on the radiator is shot, or the relay is bad.

flush the system and change thermostat,this should fix problem. I flushed mine and i changed coolant and thermostat,it is now fine.

Hi there, if you have flushed any engine and have changed thermostate there are only two options that are left; (providing that there are no leaks) 1. the thermostat is faulty / 2. your water pump is broken and needs to be replaced
