Overheating after driving for around 25-30kms

Hi,

The fan could be bad, but based on his thoughts, I wouldn't just replace it. You could simply have a blown fuse or relay issue.

I have some questions. Does the engine overheat at highway speeds or only in stop-and-go traffic? How quickly does it overheat? Also, if you allow the vehicle to idle, the cooling fan shouldn't turn on until the engine reaches approximately 220 degrees F. If you are looking at your temperature gauge, that would be a little past halfway.

Has the thermostat been replaced, the radiator flushed, and is it losing engine coolant? Also, and don't laugh, does the heater work?

I know I asked a lot of questions, but to simply replace the fan motor may or may not take care of the issue. Additionally, there are fuses and relays that would need to be checked first before condemning the fan motor.

Let me know the answers to as many of the questions as you can.

Take care,

Joe

Hi,

By chance, when the engine is cold, did you check the coolant level in the radiator? What you described sounds like low coolant or a faulty coolant temperature sensor.

Also, if you are losing coolant but the mechanic can't see a leak, either the engine is burning it in the combustion chamber, or it is leaking into the engine and mixing with the oil.

Do me a favor. Here are two links. Take a look at the first one and see if there is anything that mirrors your vehicle. If nothing does, then we need to pressure test the cooling system. You will need the pressure tester, but most parts stores will lend one to you.
