After I changed the cabin heater radiator to my ’01 Clio it was obvious that it was not enough. Overpressure in the cooling system was still a problem. After driving, even if the car was not started in 12 hours, there was still so much pressure in the coolant system that if one opened it, a loud psssshhhh was heard. Next thing to do was to change a head gasket. Here are some pics of the process.
This was the starting point.
And some progress.
Cleaning cylinder head with sandpaper.
Engine bay, top of the cylinders cleaned.
Old gasket was a bit worn..
Closer look.
Comparison.
Fitting a new one..
Tightening order.
After this point I kind of forgot to take pics. But repairing succeeded and there was no more overpressure problems.
Sail on!
