H3 2006 temperature problem

[bull5]

Hi
I have an issue with my h3. The temp. gauge is constantly beetween 1/4 and 1/2. Last year the read was between 1/2 and 3/4.
In motorway the temp is constantly 1/4. Do you have an idea avoit what it can be the cause? Thanks for your inputs.

Most likely is the coolant temperature sensor

Funny you should say that. I just made a video on how to fix that for the Alpha only, but the same principal will apply for the I5. Just a different location of where the sensor is I am guessing. Now Bull5 I cannot guarantee that is the problem, but to give you an idea how to fix it you can check out my video:

Mine was dead when I bought it. 3.7L. Cheap and easy to replace. Passenger side at the back of the head. Get a new one and you'll see what it looks luke.

Hi
Thx for the reply.
have no p code. It can not be the thermostat? The temperature gauge is moving. Just when I'm driving in a motorway that the temperature is going down till 1/4.

Could be a stuck thermostat, does it take a long time to warm up?

Yes take more time than before

Mine is doing that. T-stat seems to be stuck open. Scan gauge says temp is 168/172 and that is as warm as it gets.

Yeah, mine's the same way. Going to change next week.

No p code for thermostat exists

It's probably the thermostat, I'd go ahead and replace it.

Check the upper radiator hose after a cold start. If it is warming up or there is pressure then the tstat is stuck open. Usually it should pressure up around the tstat opening point (180-190*).

If it takes too long to warm up then thats another indicator of an open tstat. Also very low highway temps
