i have the manual to radiator but it has a retarded picture of swiggly lines of where the engine drain bolt is. i know your suppose to loosen both the engine drain bolt and the radiators. can anyone show me a picture of where it is? its not the same as the bleed bolt is it?

So your saying you want to know where the drain bolt is that drains the coolant from the block?

lol. i hate the spot where the thermostat is located! i just changed it. figures out that it wasnt working correctly and was clogged of some sort. now my car runs smoother with no overheating. life is good. 8)

im not sure if it ever leaked. i believe that the hoses werent sending enough coolant to the radiator. something was wrong with the thermostat that's all.
