SOURCE: I have a 1999 Toyota Camry (4 Cyl). It comes up

The sensor for the fans is in the rad at the bottom. T-stat may be bad or the rad may be clogged. Cooling system needs attention.

Hi,

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).

Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.

Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.

Fourth, make sure the radiator (and associated hoses) aren't blocked.

If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.

However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.

If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Cheers,

SOURCE: Toyota Caldina cambelt broke. Valve damage?

Sorry to say there is most likely quite expensive damage to the valve train and pistons. A new cam belt can be installed and the motor rotated to see if it is turning freely after which you would do a compression check (lack of compression will indicate bent or broken valves). I've never seen a diesel break a belt and avoid damage, virtually always a catastrophic failure.

You may have to replace your thermostat. If the thermostat is not working properly, you will have over heat. You make also have a bad thermostat gasket and that's where the water leak from. It might be leaking a little at a time and the engine is hot so its dry before you can see it.

Coolant temperature fluctuates


What you are describing is a cooling system low on coolant or a sticking thermostat.
I might leave the thermostat out and drive it a few days to see what happens. There could be something in the system that is restricting flow, or it could still be low on coolant.
Its possible something is not right with air flow thru the radiator or the fan clutch. There could be a restriction in the ac condenser.

Engine coolant Temperature gauge fluctuates


Watch the temp gauge when the electric radiator fans come on. The temp sensor that controls when the fan comes on may be faulty.

My radiator on my 1994 toyota hilux sulf is over heating just sarted in last few days. Temperature gauge fluctuates when i turn air conditioning on.how do i fix this


First check if you have any leaks in the cooling system , then check if level is correct(radiator and expansion tank , check level when car is cold , never open radiator when it's hot).
Then verify operation of radiator fan , if it's electrical fan it should comes on when temp. goes over normal,
if it's a clutch fan- it should pick up a speed and be more loud. If fan is not on and engine is starting overheating , check upper and lower radiator hoses.
If upper hose hot and lower hose cold or warm then you might have stuck close or prtially closed thermostat , difference between lower and upper hoses when t/stat works ok is about 10-15 degrees,
not really noticeable for hand.So if you don't feel a lot of difference between hoses temp. , and fan is not on , check fan or fan clutch itself.
If lower hose cold , replace thermostat and purge system.
If everything above is working properly , and it's still overheating , you may have bad water pump or head gasket.

Water cooling system problem...


It's possible that the thermostat is defective.
Also check that the overflow hose and resivour are not cracked.
Check the engine oil, if it looks foamy then you may have a cracked head.
