Firstly you need to define overheating Is the car just running hot or is it pushing the water out ? Ignition timing too advanced or a lean mixture cause the engine to run hot. But if the system is losing the water then you need to look Further. If the oil level is ok that is fine but check the colour of the oil. If it is milky then you might have water getting into the oil. Remove the oil filler cap and see if that has got a milky residue on it or inside the tappet cover. This could indicate a blown head gasket or worse a crack somewhere in the engine. If you have access to a radiator pressure tester check the system for water leaks, If you are losing water through a leak this could be causing the over heating. Check the water is being drawn from the reservoir, check the level in the radiator as well as in the reservoir. If the radiator cap is faulty it will lose water and also might not draw water back from the reservoir. If you can borrow a pressure tester the remove the spark plugs and pressurise the cooling system and let the car stand for a while. then leaving the spark plugs out turn the engine over with the starter and see if water comes out of the spark plug holes. This would indicate a leak into the cylinders.
If the car is parked and when you start it it runs irracticaly and then clears it could also indicate that water is getting into the cylinders.

Why would a tropper get hot if the radator is full?
If you have an old ISUZU Trooper, the radiator thermostat may be not working. Therefore, it will not let cool water from the radiator into the hot engine, even if the radiator is full. Have the thermostat checked and replaced, if necessary. Good Luck
1994 lhs it s overheating?
We had the same problem with our LHS. We first replaced the thermostate and it still happened. So we keep looking and the lower radiator hose was colapsing. You might check the hoses after you replace the thermostate. Hope this helps.

Bad thermostate Bad water pump belt slipping Could also be due to a bad radiator fan motor or relay.
Your 2000 elantra has done 160k and just this week the water in the radiator has started boiling and the temperature is almost hitting red can it be the thermostate the radiator or the head gasket?
I would start at the thermostat. Problems with the radiator and head gaskets are usually presented as visual leaks. But clogged passages in the radiator would also cause overheating issues, so have the cooling system flushed.
Where is the thermostate in a 1997 Mercury Villager?
At the engine end of the upper radiator hose.
Would the radiator fan not working cause overheating?
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
