Hello,

I have a little temperature problems. highway speed boxster 2.5 temperature rise near 205, then cooling system is start working(blower). decrease temperature lower 200, but not normal level near 180.

I change thermostat and wash radiators, but it's not help.

Could be same sensor problems ?

Thanks your answers

If you have cleaned the radiators (by removing the front bumper), the coolant is new & level is OK, you may have a problem with the water pump itself. Some of the early cars had a problem with the pump vanes wearing or breaking off after a high km. You may have to invest in a new water pump & drive belt.

Thanks your answers,

I check radiators both side, it's looks very clean. I'm not removing front side bumber. Maybe i must check one more time radiators.

Belt looks almost new, but i don't water pump condition.

What are your ambient temps???
You may have lost some impellers on the waterpump, they are quite problematic.

guggis - most of the debris that can block the radiators get between the coolant radiator and the aircon coil - they are sandwiched very close together and lots of leaves and crud get jammed in between the rads causing lack of airflow.
Try the search function button "overheating" for more details.
