1995 Opel Corsa
It is a special car
I don't know why water boils most of the time. Boiling water and overheating the engine is the biggest problem. I checked the radiator and the thermostat, but there was no problem. And the radiator fan works, I think most of the time.
Please help me because no one can solve this problem.
It is slow, but comfortable.
Would you buy another car from this manufacturer? Yes

Maybe a bad head gasket? Check the cylinders compression. Also maybe the thermostat stuck in the closed position? Take it out, put it in a pot with water, heat it and watch if it fully opens as the water starts to boil. Also make sure that the cooling system is fully purged (all the air must bubble out).
Finally, check the water pump for rotten or broken blades.
My Opel Corsa does exactly the same and more. Sometimes I would be driving (in traffic or open road) and I would hear a click in the fuse box. The temp needle then goes from 90 into the red within 5 seconds and I pull over and switch off my car. Then it would SOMETIMES not start again for about 5mins.
My top gasket has blown and been replaced, radiator fixed, 2X new thermostat.
HELP! Don't know what to do!!!
All the comments are good regarding the overheating problem! Except you guys forget one easy step to look for, and that is to replace the radiator top or bottom rubber hose... normally these hoses tend to collapse and mechanics are very quick to say it's head gasket blown and that's not true... I have done quite a few cars with same problem... and most of time I'm always right.
