Rahimdad Posted September 20, 2016 Report Share Posted September 20, 2016 Could be a dirty radiator, Just go to one of the radiator shops and ask them to clean it properly and replace the coolant. Most cases that solves the problem. Link to comment Share on other sites More sharing options...
gautam Posted September 20, 2016 Report Share Posted September 20, 2016 More than likely the viscous fan no longer works as it should. When it starts to fail it slows down the fan's rotation speed, so check if you can spin the fan by hand when the engine is switched OFF. There should be no free rotation when you try to spin the fan, or, you can take the vehicle to Barry to check out the condition of the radiator fan. Interpreting the condition of a viscous fan requires some experience of these fans, so don't think it "looks OK". Have it checked out by a professional mechanic.

Saleem Posted September 24, 2016 Report Share Posted September 24, 2016 check the coolant age as it\f it's more than 3 or 4 years you need to replace it Check the coolant pump pressure as the coolant is not circulating efficiently it would over heat faster than usual check coolant thermostat (the therm-mechanical) as if it's not opening on specified temperature or opening partially it would over heat and finally (worst case scenario) use a towel to squeeze water hose during over heat if it's sold and not flexible to be closed by hand pressure so you have a gas leak from cylinders heads to cooling jacket that would require replacing heads gaskets and some time surfacing the heads. 1 Link to comment Share on other sites More sharing options...
