A few weeks ago, the coolant system overheated and steam poured out of the cap and tank of the collant system.

The temp went through the roof on the gauge.

I bled the system about a month ago after it had done this the first time.

The compression test was fine which means the engine is sound and that no liquid is leaking in to the engine.

The most noticable thing is water coming out of the exhaust but not sure if this is related or not.

The only other thing that I havnt changed is the Radiator which does look poor visually, would this be the reason for the overheating? All help appreicated, many thanks, Andy
