So My 91 protege is leaking coolant, from a place that I cant even discribe. I have attached a picture of the spot. Its on the front of the block, behind the manifold, and there appear to be four, each on the bottom front of the block, about where each cylinder is. It is constantly dripping, and if I blow into the radiator cap, it jet streams out. Any help would be fantastic, I am just lost on this one. Mahalo-

These things are called freeze plugs and yours are corroded. They can be eplaced. I have not done it myself. But I think all you have to do is drain te coolant, punch a hole in the plug and pry it out, clean and everything and put a new one in. They are friction fit. While the plugs are out you have a great oportunity to flush the engine block.

Some one will likely recommend' bars leak'. I don't. The stuff could cover the ECT sensor or the sensor for the temperature gauge. Then you may overheat the engine without knowing.

 

Had this happen on an older Oldsmobile and the whole engine had to separated and lifted up from the tranny to get the one that was leaking.Plug costed acouple bucks, but was a major job for that one.
