Hi,
Most normal causes for overheating would be:
- clogged radiator,
- insufficient coolant level (radiator and reservoir);
- too soft radiator hoses;
- defective/leaky water pump (impeller);
- water pump belt/tensioner;
- thermostat (mechanical);
- thermal switch;
- radiator fan, fan clutch;
- fan relay;
- fan fuse.
In some instances, the fan only works in conjunction with the A/C and/or
heater and therefore would only work if either of those two are enabled.
Should your particular vehicle be using a radiator fan with clutch,
that could also cause the fan blades not to spin even if the fan motor
is turning.
Pls check the above mentioned components.
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.
