Drain the coolant, flush the system, replace the thermostat, and pour in a fresh supply of a 50/50 mix of antifreeze and distilled water. If it still overheats the water pump is suspect.

What is causing my truck to still overheat after I replaced the thermostat.

What is year--make--model? Are you just going by the temp gage, are there other overheating issues? Is the coolant boiling or anything, are you losing coolant?
Some possibilities, air in the system, radiator, radiator fan, water pump, combustion gases in the coolant. I'm sure I'm leaving something out?

Land rover problems

need to make sure that the thermostat is working properly and the system is this by idling the car for about 30 minutes and observe the goings on with the cars systems if its gonna overheat it will do it no matter what..idling or driving..look for pressure build up in the system by squeezing the upper hoses if the seem to get inflated and stiff you may have pressure weepage into the system..this will maybe call for new head gaskets..or at worst an upperengine rebuild..

My 1999 Cadillac El Dorado overheats and turns of a/c

You may have a blown head gasket. Are you losing coolant? 1st check to see if your coolant level is good, if it isnt make sure you top it off, run it for 20 minutes watching the temp. and putting the heater control to full hot to be sure you bleed out all the air that may be in the system, after 20 min or when the temp rises too hight turn it off, let it cool, open and top off as needed, repeat after topping off, do this till it no longer takes any more coolant and is no longer overheating. If your still overheating and slowly losing coolant you more than likely have a blown head gasket, they have a sniffer test you can do at the radiator cap your local parts store carries them or your local mechanic can run the test.

Overheating coolant boiling out into reserve tank

you have a blown head gasket.. doesn't have to have coolant in the oil for a blown head gasket... if hoses are rock hard when running then you have exhaust leaking into the coolant via a blown head gasket...

'02 626 overheated earlier in the week. drove home. appeared to be out of coolant. replaced overflow tank(seal blown), added coolant, however it still overheats. what else to check?

Whenever you overheat once, then the thermostat must also be replaced. It is operated by the expansion of a contained wax pellet, and overheating causes permanent loss of wax.
However, you may also have caused a head gasket leak now from heat warpage. If the thermostat does not help, then borrow a cooling system pressure checker from a place like Autozone, and see of it holds pressure for 5 minutes after pumping it slightly above cap rating. Then start engine and see if it is steady or oscillating from 1 cylinder leakage.

Removal of the thermostat from the cooling system is not a good idea. This upsets the coolant flow rate in the system, and that can cause the engine to overheat, even when no other problem with the cooling system exists.

Try to identify the cause of the overheating.

Ensure that engine tune, or other engine mechanical fault condition is not the cause of the overheating, then go through the checklist following:-

1) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
2) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
3) Check coolant reservoir pressure cap is serviceable,
4) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
5) Check for combustion gas bubbles in the coolant reservoir while the motor is running - this indicates a blown head gasket. If in doubt, take it to a radiator shop and ask for a combustion gas check on your radiator.
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

If all above ok, replace the thermostat again (also ensure it is not installed upside down) - faulty new thermostats are not unheard of.

Sounds like a blown head gasket from multiple overheatings. Parts retailers have a chemical that can determine this. To use it the coolant level in the radiator needs to be a little low so no coolant will be pulled into chemical container. Engine needs to be at operating temperature. The containter is pushed onto radiator cap opening and bulb squeezed numerours times for about 2 minutes. If the chemical changes from blue to yellow (or green depending on manufacturer) then the head gasket is blown or head has warped (or both).
