Possible head gasket failure

[Dave]

If your overheating and the rads are kicking in quite often check your rad itself cos all the fins may have corroded and fallen out. Has it done it again since? Normally if you get pressurised coolant it's hg popped but change the rad cap first cos it might just be weak as all engines run under pressure. I ran for 6 months with a blown gasket tho but not everyone can get away with it as long
