I love this place!
So. My 2002 V8 Explorer just blew some kind of hose, seal, or whatever, such that coolant is all over. I can't tell where it's coming from because of that cover.
Looking at it, there are four "things" that appear to be holding the cover in place.
But on mine, they all seem to have square drive heads. Hmmm. Never seen that before!
Edit:
Here's a picture of the cover:
Here's a shot of the odd nuts that held the cover on:
Those nuts' square heads are 1/4". I just used a ratchet with a 3/8 to 1/4 adapter to remove them. The ball detent held onto the nuts nicely.
With the cover off, it seems like there's coolant all over the top of the engine. I'm suspecting the intake manifold or it's gasket, but that's for another thread, I guess!
