Re: Weird coolent leak

There is a core plug in the back of the head. Could that be where the leak is coming from? I don't think there's one in the block back there, but it's been a long time since I've been in there.

Re: Weird coolent leak

Get a mechanic stethoscope and listen back at the back of the head to see if you can hear the pressure release after the engine's shut off...

Re: Weird coolent leak

Fill it up, throw about 15 psi at the radiator cap and you will find any leaks.

The 'Water' (anti-freeze mix) in the top of the block and in the heads often turn to steam when the engine is shut off and the water pump stops turning.
The 'Coolant' heat soaks, and can turn to steam.

Tape a piece of toilet paper under and/or over your core plugs.
Then run the engine until you reach operating temp.
This will tell you if it's one of the core plugs leaking, or something more sinister...
