Hi folks, just new to the site and it's mainly to get an owners opinion on what might be causing my car to overheat. My overflow tank burst a few weeks ago and I had it replaced as well as the thermostat (which had been stuck in the open position) It worked great for about 100 kms and then started to overheat again, and burst the resivoire tank, again. Anyone have a more reasonable solution than replacing the cylinder head? Greatly appreciate any input and thx
