So I took the ke35 for a longer drive than usual the other night. On the way home, I sat on 90kmh for about 40 minutes in the pouring rain. Everything seemed fine until I got home and noticed the steam pouring out from the side of the bonnet. The overflow tank was full and bubbling away. The temp gauge was on about 10%, which is where it normally sits.
The next morning I checked the coolant level in the radiator and of course it was low. I checked the plugs looking for a clean one, wondering if I'd blown the head gasket. All ok here.
I flushed the radiator, changed the thermostat and put a new cap on the radiator. The old cap was really loose when compared to the new one, so I assumed this was the problem.
Driving around again, it seems fine, but I haven't had it on the freeeway. The temp gauge was still on 10%. I wondered why the temp gauge never went up when it was bubbling away. So now I've replaced the temp sensor and instead of sitting on 10%, it's now sitting on 90%.
Now I don't know if it's actually running hot all the time or if there's nothing to worry about.
How can I tell where the temperature is really at?
Sorry for the novel.
Thanks.
