Hello Neil
Didn't realise the car in question was yours. Before you brought the car to us, you had been the victum of gobshite's that didn't know there job. 2 idoit's that didn't see the crack in the rad, or the second fool who put oily water into the cooling system.
We flushed the cooling system several times and replaced the header tank and cap, as these were damaged. No leaks and no overheating, when the car left jomo. The car is a very nice tight car, and well worth keeping. As Alan said, you should be pisse at the gobshit's and not the car. If you want. come over some Saturday and we will have a look at it for you, and pressure test the cooling system for you.
