check to see if the lower radiator hose is collapsing, if not then take the fan belt off and check for slop in the water pump. Somethimes the pump can go bad and not leak. let me know if this works out for you.

Are you using a TOYOTA thermostat? The OEM 'stats have what we refer to as a "wiggle valve", and the 'stat should be inserted with this valve point straight up to 12 o'clock. This allows air to be purged from the cooling system. If everything is good, you may just have a "air blockage"; the system will not pump air in the cooling jacket, the water pump will just cavitate the air, resulting in your overheat condition...

I have hiace 3L with new head water pump,radiator,clutch fan,thermostat,radiator cap,fuel filter,new timing belt and it over heats after 100 km and has blown the cylinder head gasket twice since . any...


probably a dumb question but was the engine block skimmed and on certain cars you get different thickness gaskets for different performance heads, and is the timing correct?

1994 toyota camry- recently replaced radiator, timing belt, water pump and thermostat- no heat when idling- lots of heat when reving the engine or driving


check your antifreeze mix, this is a common problem when your antifreeze mix is too much antifreeze and not enough water. 50/50 mix to 55/45 mix is ideal for most applications. too much antifreeze and not enough water will not transfer heat as well as the proper mixture.
make sure your mixture is 50-55% antifreeze.

New water pump.... new timing belt.... new radiator cap... but the idiot mechanic has not done the obvious.

1. Change the coolant thermostat located under the hose fitting on the manifold where the top radiator hose connects to the engine.

2. Check the radiator fan switch for proper operation. When in doubt change it out. A $30.00 switch isn't worth risking a complete engine overhall.

3. Do a compression check on the engine to make sure all cylinders have close to the same amount of comression. Overheating can cause head gaskets to weaken and fail. Performing the compression check would verify that both the cylinder head, valves and head gasket are still in good working order.

4. (Applicable only to cars with a belt driven fan) Does the fan have a fan clutch? I did not look it up yet. If it does then the fan clutch can also be a problem if it is not turning the fan when the engine is hot.

For cars with an electric fan the switch in step 2 applies as does checking the fan for proper operation.

5. Fire your mechanic! If there is one thing I hate it is a mechanic that only does half the job vs checking out all possible causes! Your car should have never left the shop in a state that it could over heat AGAIN. Time to have a chat with she service manager and the service managers' boss! They owe you some free labor!

Thanks for using FixYa.

1994 Toyota truck over heat we change water pump , head job, radiator thermostat


did you guys flush the coolant system and make sure there wasnt any corosine in the radiator, plus on some of those models you have to make sure that all of the air bubbles are out of the system or it get almost like vapor locked and the water wont flow throught the system,, also check the heater core try by passing it and running the motor you might have a plugged heater core also ,,,

Over heating


Sounds like a bad water pump. If there's no white smoke coming from the exhaust (head gasket) and the radiator and thermostat are good, either the belts are slipping or the waterpump is on it's way out.

Hi i have a 1994 toyota estima which has started to over heat when sitting in traffic. I am not sure were the thermostat is located, as i guess this is the problem.


Thermostat, coolant sensor, fan relay etc. First check the coolant level, check for leaks. Check if the fans are on when the engine is hot, about to over heat. If equipped with two fans they both should be on. If its all good have the system flushed and a new thermostat installed. If you want to change the thermostat yourself follow the big hoses that are attached to the radiator. Look at each where they attach to the engine. It should be apparent where the thermostat is at the end of the hose. After replacing the thermostat if you don't top off the coolant and there is air in the system the car will over-heat with the new thermostat. Some times radiators have air bleed valves on top. If not then jack up the car a little. Jack it up in the side the radiator cap is at so the air can work its way out. To fill it add coolant when the car is cold, off, and jacked up. Leave the cap off and start the car this is so the thermostat opens and the coolant flows. Continue to add coolant until it over-flows close or put the cap on. Put coolant in the over flow reservoir fill it to the low level. If the radiator has the air valve you don't need to jack the car. If you did it right the car should not over heat and the heater should be working.
