I have a 1985 xf with a mild 351 clevo in it which continues to over heat. I have a chinese 3 core alloy radiator which I bought off ebay for 200bucks, a Spal 15inch thermo. It use to when cruising sit around 100degrees so I changed the thermostat now sit around 80degrees cruising but once I get stuck in traffic it creeps back up to 100 and sits and then just continues to climb even when I cruise again.
I don't have a shroud on the thermo fan is it worth me getting on made up? Or am I better off upgrading the radiator? and if so can anyone recommend a good brand or any other advice on the matter.
