You may have a blown head gasket or intake gasket you will have to have it looked at to determine the cause of the fluid loose. you may be able to find a color dye tablets that you can put in the radiator and it will change the coolant color to something that is more visible.

SOUND LIKE HEAD GASKET LEAK.CHECK ENGINE OIL FOR SIGNS ANTIFREEZE CONTAMINATION..OIL WILL LOOK LIKE MILK SHAKE.IF USING WATER IT EVAPORATES AT 212 DEGREES. ENGINE COOLANT TEMPERATURE CAN CLIMB UP TO 220 DEGREES.IF OIL IN CRANK CASE LOOKS GOOD.ADD 50/50 WATER AND ANTIFREEZE. ANTIFREEZE WILL RAISE BOILING POINT TO KEEP COOLANT FROM EVAPORATING.SEE IF YOU LOSING WATER ITS BOILING AWAY LIKE WATER IN A TEA KETTLE.

93 4runner new radiator new t stat still overheating.


Check:

1. Thermostat. Replace with an OEM one from the dealer. 2. Radiator. Make sure it's not plugged up. 3. Radiator Cap. There cheap from the dealer and I consider them a maint. item. 4. Water pump. How many miles are on it? 5. Fan Clutch. Make sure it has some resistance
6. Temp. Sensor for the gage.Have you checked that the electric cooling fan is turning on when the engine reaches operating temp? A faulty coolant temperature sensor will not trigger the fan, or the fan itself or fan relay could be shot. You might also have a head gasket leak that is not into the cylinders, so it would overheat without causing milky oil. Another possibility is a clogged radiator -- with 15 years on the vehicle, it's quite possible. Have the cooling system pressure checked, and replace the radiator cap for starters -- if the radiator cap isn't holding pressure, overheating will occur rapidly.

In the 95 4runner, what should the temperature


Which engine does your forerunner have? They are not known for overheating, so you may have a problem in your cooling system. Is the system losing water? The first thing to do is get a pressure test of the cooling system done. At the same time ask them to test the thermostat. If all ok, Have the engine and radiator reverse flushed, and add corrosion inhibitor. Should be ok after this is done.

1989 Toyota Land Cruiser overheating- REPLACED ENTIRE COOLING SYS


Do a cylinder leak down test. Hook up a airline to each spark plug hole. Bring each cyclinder to tdc and listen for air leak. Possibly in the radiator. You can also reverse the process by doing a radiator leak down test. If you hear bubbling in the radiator bad head gasket. Remove and replace head gasket.

Lose of water


Hi,

One possible explanation is that the leak is small and the water escapes as steam. This then would lead to no immediately visible water leak under the vehicle and being small, the coolant system is still capable of preventing an overheat. Most likely spots would be the junction of the radiator hoses either to the radiator or to the engine side. One possible way to check is use your Toyota as you normally would but before shutting down the engine after a long drive, pop open the hood and check where steam or water might be leaking.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
