[QUOTE="Tazza, post: 129109, member: 82"] How does your engine start, have you had the head off at all? not everyone knows that in diesels, you need to make sure the gasket you use is the same thickness, top clearance is very important, differences of .1 or .2mm makes a big difference. If your clearance is too small, your compression is too high and you get too much heat. Generally there are only a few reasons an engine will run hot, exhaust gasses getting into the cooling system, be it a cracked head or failed head gasket. Not enough coolant flow Stuck thermostat blocked radiator not enough air movement. Compression that is too high. If your radiator was in good shape, the outlet side should be a fair bit cooler than the intake. If it's not transferring heat, you may have sludge or something in it, sure, you can run cleaners, but if it was already plugged, you stand little chances of it cleaning it, like a blocked injector, you add cleaner to the fuel system, but it's too little too late.
