2000 Ford focus se wagon overheat

Any gauges that do not read correctly like they should ? Sounds like a bad intake air temp sensor or coolant temp sensor

check you're fuse's for the fan. At highway speed's there is enough air flow for the radiator to cool the motor. If not run the fan from a switch from battery to fan as a last resort.

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..

It's the first hint about the new car you really need.

sounds like possibly the coolant fan inop check that

Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.

I would check to see if the radiator fans are coming on. Also check the freon pressure in the A/C system.

I had problem with overheating on motorway when I drove over 60 mph i changed thermostat,radiator,thermostat housing, nothing helps.Then i find out that the problem was AIR IN THE COOLING SYSTEM try to squeeze all rubber pipes especially where is coming coolant to radiator.

if all else fails, change thermostat, and bleed are from system if needbe.

Try the right hand stalk. It should move backwards and forwards to switch on and off the rear wiper.
