I have searched the forum but have not found anything that appears to be the same problem I am having. I have a '93 twin turbo and there appears to be a coolant leak on the drivers side near the rear of the engine. Not sure where it could be coming from but I am sure that it is probably NOT good. Does anyone have any suggestions or recommendations? What can I check before replacing the engine which I would rather not have to do. Any suggestions would be greatly appreciated. Thanks in advance.

 

just beneath the oil filter on the driver's side of the engine is where one of the main coolant lines in attached to the block. The bolt could be loose, or it could be coming out of the hole in the block where the water temp sensor is screwed in.
both are a bitch to get to.

There's a coolant line that goes to the throttle body. Check IT!
