Cause it usually basically simple while the engine is idling the heat is being removed from the engine block by the water pump and the thermostat there's not a great demand for much heat to be removed so I title the car's fine the minute you put it under load it increases the amount of heat that needs to be removed from the engine block itself what I suggest you do is get a digital thermometer a digital infrared thermometer check the temperature of the radiator radiator near the lower hose and also check the temperature of the radiator at the upper holes if the radiator temperatures do not match are very different and the lower hose is cold that means that the radiator fluid is not circulating you may need to change the water pump and check the radiator for restrictionstake the digital infrared thermometer containment within the radiator core itself that will let you know where they're not the heat is being removed from the engine if the radiator is not warm or above 212 degreeshe does not being removed from the engine which means that you have a circulation problem remove the radiator and have it repair if you have ever used any radiator stop leak in your radiator or your car which is only a temporary repair that is often costly later I suggest you remove the radiator upper holes and flush the system removing all of the radiator stop leak productchange a thermostat and check the circulation of the water pump that should cure your overheating problems keep in mind that after all of this is done the system must be bled all of the air must be removed from your cooling system if not it will calls the radiator fluid to boil over depending on your atmospheric pressurewater begins to boil at 212 degrees at sea level and as you go and as you go up in atmosphere the temperature begins to drop at what time it boilsI hope this helps you good luck and God bless

The radiator fan should come on at 220 degrees. You could bypass the fan relay to power the fan while you are driving until you can get the actual problem fixed.

My car is overheatting i changed the waterpump/thermostat/heatercore/reservoir and sensors


Does it slowly overheat while driving down the highway..If so the radiator is probably clogged..It can be partially clogged and cause the car to overheat,,but usually takes a little while...If it overheats in traffic..(stop and go ),,but does fine going down the road,,then it make sure your fan is coming on..

Overheats ive tried the obvious solutions and it still overheats any suggestions


note if it overheats on the freeway or in city driving. If it overheats soon after you leave the house then in has to be the thermostat. If it overheats at city driving where there are lots of stop and go driving or while you are parked with the motor running, then check the radiator fan function properly. If it takes a while to overheat and tend to do it when driving on the freeway, it is a clogged/dirty radiator. If it looses coolant due to a leak, then it will also overheat. The least likely cause which don't even pertain to newer car is a retarted timing. A retarted timing causes a car to loose noticable loose of power accompanied by overheating. A retartded timing is usually common in older car where timing is adjustable by turning the distributor. Your car is exempt from this.

you have a 1.8 liter turbo engine correct? it is the water pump that is driven by the timing belt. 100% positive this is correct i have replaced countless water pumps for this reason. the reason it overheats while driving is becuase the splines on the water pumps plastic impeller are gone and it is just freewheeling on the pump shaft. at idle the pump spins slow enough to get the impeller to turn. very very very very common. replace water pump timing belt and tensioner.
