    1996 2.4L 4 cylinder with same problem. Replaced radiator, fan clutch, water pump, and thermostat. Not using any water and no bubbles. Radiator shop says flow is good. Unless it's either NAPA gave me an undersized radiator or something strange is straining the engine (like maybe a cracked catalytic converter???) I don't know what else it could be. The engine cools down immediately to normal when the heater valve is activated.

If its losing water it could be a head gasket or cracked head.

    if it is boiling over and you dont have a cracked head or blown head gasket the simple thing to do is replace the radiator cap it worked for me. make sure you use the factory recomended cap for your car or truck.

Did you check your thermostat you can put them in a pot of water and boil it if it opens you know its good if not you got a bad one. i have a 97 tacoma and got two bad ones before i got a good one you can also ask for a 160 degrees thermostat that will make it run cooler and pro long the life of the motor

My truck keeps over heating after a new radiator and new water pump and new fan clutch and new thermostat and there isn't any water in the oil


Air lock find out where the bleed nipple is and undo carefully if engine hot and wait for the water to stop spitting and hissing ( like a kettle) Top up with water/antifreeze careful to pour slowly to avoid air bubbles accumulating.

Here are a few things to try. Check your Radiator cap pressure as a weak cap will boil over more quickly. Replace your Temperature sending unit. There may be 2, one is for the dash gauge and the other is for engine control. Unless you have other signs of overheating you may not be overheating at all, just a bad sender.

Next, the cooling fan clutch is what the fan blade is mounted on. This is checked by using a Timing light with a RPM tach made into it. The fan clutch "locks" at a variable temperature. In cold weather it slips internally. In hot weather it engages or "locks". A mechanic measures the RPM of the blade to the RPM of the engine. This tells if the fan clutch is slipping too much internally.

Before considering a new water pump try a free scan at Autozone or Oreillys. If your Catalytic converters are plugged the engine will overheat. You should have a Code for this problem in the onboard computer. About all you can try after this is to remove the Thermostat completely and see if the engine still overheats.

You will have to replace the New Thermostat again because the other engine controls will not work right without it. But without the thermostat you can test for collapsed Radiator hoses at say 2500RPM or above. Thats about all I can think of, the water pump would cost the most. The cap, sensor-sender, fan clutch, and hoses are not that expensive.

My car is overheating and i need to know how to put in the water pump?


Is the water pump leaking coolant? If not, then why do you think it's bad?

If the engine is overheating, there are several other things to look at before you consider the replacing the water pump.

Are the fans electric motor driven, or fan belt driven? If fan belt driven, replace the fan clutch. If electric motor driven, check the fan control module and/or fan motors to make sure all is good there. Fan control module tend to fail in weird ways, so if nothing is wrong with the motors, replace the module.

Always, always, replace a thermostat that has overheated. Once overheated, they consistently fail. Make sure you properly refill the radiator with coolant after the stat is changed.

Check that the bottom radiator hose does not collapse.

Check the radiator for corrosion. Boil the radiator out, or have it done, or replace the radiator.

What can make my 2002 toyota tamoca over heat


One of the most common reasons for a vehicle overheating is a stuck thermostat. It can stick or freeze in the closed position blocking the flow of coolant to your engine. The easiest way to check if your thermostat is not open is to feel the upper radiator hose. Once the engine warms up it should become warm. If it does not get hot the thermostat is probably not opening.

A second common cause of overheating is a leak in your vehicle's cooling system. If your vehicle is loosing coolant there will not be enough left in the vehicle to keep it cool. This is easy to diagnose as the radiator will be low on fluid and there will probably be a pool of coolant on the floor of your garage. Look for leaks in the most common places like around hoses and around the welds of your radiator. If you can not find the leak you might need to take it to a shop to have the cooling system pressure tested.

The third cause is a faulty water pump. The water pump is a vital part of your cooling system since it is responsible for circulating coolant through your engine. With a faulty water pump your vehicle will not run for more than a few minutes without overheating.

The fourth cause of overheating is a bad cooling fan. There are two types of fans, electric and mechanical. The electric fan should come on automatically once the vehicle reaches operating temperature or when the A/C is turned on. If it doesn't you should have it replaced. The mechanical fan will run all of the time but has a clutch which makes it turn faster when the engine heats up. With the car turned off the fan should not turn too easily especially when the vehicle is warm. You can also check for signs of leakage from the fan clutch. If you see any problems have it replaced.

The fifth cause of overheating I will talk about is a clogged radiator. Over time the radiator can accumulate deposits of rust and debris. This is especially true if radiator fluid has not been flushed on a regular basis. If you suspect a clogged radiator you should take it to a shop to have it professionally cleaned.

Those are some of the most common cause for vehicle overheating. Vehicle overheating can cause a great deal of damage to your vehicle. If you are experiencing trouble be sure to fix your vehicle or take it to a quality mechanic as soon as possible.

Overheating engine


Was the thermostat put in backwards? I know this is a silly question, but I've seen it happen. The water pump will fight it if it is. Another thing are the coolant passages, are they flushed out? Also, if that fan clutch is the original one, I would go ahead and replace that as insurance against the water pump breaking.
