I have a '89 300E 2.6 it had a coolant leak for a while so I took it to one mechanic and he said it was a freeze plug. He said I can put a can of block seal in it and it will be ok until I can afford to fix it. So I ran a couple different sealers through it but nothing stopped the leak. Another mechanic said it was the water pump, and he was right. It took me most of today to replace it but I got it done. Now there is a issue with it over heating. I put a new thermostat in it today also. I checked the hoses and there was a lot of pressure in the system, so I thought I will just take out the thermostat and then the coolant will circulate without the preasure. Even without the thermostat it is over heating and the preasure is still there. How could that be? Could it be the radiator got clogged from all that stuff I ran through it? Can this type of radiator be cleaned out at a radiator shop or do I need to get a new one? If you think that is the problem. Please help

Do you have a single serpitine belt on this engine? If so it must be put on correctly or the water pump will run backwards.
Did you put in the right water pump? Some run one direction and some the other depending on the type of drive belts your engine has.
Is the bottom radiator hose sucking down? Is the top one? Radiator hoses that collapse during overheating are sure sign of a clogged radiator.
