Reply to "Some good...some bad! It passed the MoT test ... But it over heated on the way home."

I'm waving the white flag.....I'm going to paint it black and put it in a dark corner of the garage and never mention it again......I admit defeat and will endeavour to find someone who knows better as I dare not run it again for risk of doing more damage...I'm sure the temp gauge is bust though as I started it this evening it and it shot immediatley to 200 degrees again, the sensor is on the expansion tank and that was cool to the touch, within 3-4. Mins of the engine ticking over it rose agin to the max about 230 degree, the engine by then smelled hot and I could hear hissing...so enough is enough...
I will however test it again once the IR temp gun arrives....I'll keep everyone posted!
