Hi again all . This is a smpile thing but I just can't find the coolant release valve for the engine . I found the radiator valve but I can't find the one for the engine . I know the procedure to change it and the ratios , but I need some guidance .

Thanks!

Forgot the model . Sorry . It is a 1991 300TE 4matic . Thanks again .

Shouldn't have to drain the engine. The drain in the radiator is the lowest point. Drain from there and flush with clear water. Then refill to spec. I believe that some M103 engines have a drain at the lower right front of the block. Mine do not, but who knows.

Jeff you are wrong, the water pump hoses are higher than the block. The drain is between the #5 and 6 exhaust manifolds under the car on the side of the block. Alot more will come out. This is the only way to do a complete coolant change.
