My Engine is leaking coolant from some place weird. Its not one of the 2 main hoses or the radiator. It looks like its coming from someplace underneath the intake manifold. Where could this leak be coming from. I have a 91 e30 with an m42 head and block from 95. I'm praying its not a cracked cylinder head. :confused:

most likely your coolant flange under the intake. its easy, and i believe either german autoparts or pelican parts has them in stock. mine was cracked a few months ago and its about an hour or so to change it

You also have a few coolant hoses that connect to the throttle body heater blocks. Check them out here:

Do the hose delete...especially if you live in a warmer area of the world...you'll be happy you did.

Second the hose delete. Ij ust finished it.

BUT, if you don't want to and need replacement hoses, you can have mine. Just pay shipping. I bought new oem hoses and never used them b/c I did the delete.
