Allright then, new heat gasket kit, some hoses, head skimmed and a new temperature sensor as i melted the old one. The header tank is flushed but needs another flush, still not clean enough for me.
Did a few test drives today so couple of pictures, back on the road ;
Runs good but noticed a few bolts coming loose again, some of the cam cover and the engine lifting eye bolt needs a new one i think. But that's no big job
I do think the car makes some higher temps when driving then before... But maybe it's just me being a bit Cosworth paranoid at the moment

Anyway, here a couple of pictures showing the meter/norm.
And one while driving, not easy
Gonna take it easy for now with the car.
So makes your cosworth the same temp and it this the normal temp or in the safe limit being normal temperatures?
