check
the thermostat housing isn't broken where the thermostat pin pushes on the plastic housing fault with polo's
Each car overheats at a different temperature you need to look up and find out on the internet
maybe its u or da car
pull the thermostate change it as well as the water pump but before you do this make sure you dont have a air lock bleed through your heater hose return
Car overheats or can't reached the normal temperature.
theyre maybe an air bubble in the block causing it to overheat,or it could also be a bad water pump
If your brain overheats, you instantly die.
I would guess that the thermostat is not opening at the proper temperature. Once it does open proper circulation brings it down to the correct operating temperature. I think it should be replaced.
Check the electric fan to see if it is working.
temperature sensor, fan relay, or fans themselves are bad.
Shorts out and overheats or has too much resistance for some other reason and overheats.
Tough to narrow it down with such little detail, but it sound like your car's thermostat may be malfunctioning and not controlling the temperature correctly.
Beats me
