heats up and wont cool down

I am assuming you mean to advance the timing??? I took this right off the website from the maker of my water pump Flowkooler: There is a lot of misinformation about ignition timing and cooling. Retarded timing contributes to overheating. Advanced timing helps cooling. Advance your initial timing a few degrees and see if it helps the car run cooler. However, if you advance to much you risk detonation and that too will cause you to overheat.
