Guage or sensor could be giving a false reading,,, water pump bad,,check radiator for blockage outside like plastic bag in front for it, or between ac radiator and truck radiator,,,seen it happen, also light bars, winches, anything added to the front of truck will dirupt airflow,, billet grills even fog lights,, mud in radiator fins,,,

Run the car without the thermostad to see if it still overheats. If so check the heat sensor it might be faulty.

Kia 2700 overheating


could be a number of things, 1. water pump not working 2. Thermostat stuck (replace if its boiled) 3. air lock in system. 4. Head gasket. 5. cracked head/block. I presume you have checked that you belt is not broken, are there any signs of leaking around the waterpump? if there are, change the pump, If the engine has overheated, change the thermostat. these are the most common things, other than these 2 it is going to take further examination for cylinder head problems or blocked water ways. Go for the thermostat first, its probably the cheapest part to replace, and see if that cures your problem.

02 isuzu overheated


check your coolant level. Check to make sure your cooling fan is running, Thermostat could be an issue also. Also check water pump. To check thermostat feel top radiator hose when vehicle heats up if it gets hot your thermostat is probably working if it does not then ur thermostat is probably stuck closed and needs to be changed. If your water pump is leaking out the weep hole (small hole at neck of water pump) then you will need to change the pump because it is going or has gone out.

Replaced cracked radiator in 2000 Chrysler LHS but car still overheating. What could be the problem?


I had the same problem. My Chrysler LHS kept overheating. I had the thermostat changed out first and it didn't help. Then I had the water pump changed out and still did no good. Then changed out the radiator, still overheated. Come to find out the people that changed my thermostat put it in backwards. Evidently, the thermostats for these cars look different from all the others and people are not sure how to put them in. I took mine to a Chrysler dealer and they fixed it for me.

Overheating


there are three hoses leading to the water pump. the biggest one oviously goes to the thermostat housing, but the other two are much smaller 1 inch hoses, one of wich goes on the water pump and the other on the thermostat housing. if you follow the hoses one will connect to the upper part of the overflow for the radiator after hitting a T in the lines, that hose connects to the thermostat housing, and the other goes to the water pump its self.
