3.8 engine EXPERTS

Alright, i've got a coolant leak, but it seems to be coming from a very strange place.

If you are standing at the front of the car at the passenger side headlight, look at the water pump. Now, at the highest point of the water pump, there is a crevise right behind there. It is also directly right of where the tensioner pulley is connected to the block.

That area of my engine is completely covered in coolant gunk. When I rev the engine from the throttle body I can see coolant seeping out or leaking onto that spot right there. There also appears to be a small crack right there, but that could just be me. I need to know what part of the engine block that is, and what's behind the spot if possible. Also, I can see the bottom of a metal hose at the top of where the crevise is. You really have to get your head down though to see it. The leaking could be coming from the back part of that hose and dripping onto the crevise area. The metal hose appears to connect to something right behind where the tensioner pulley connects to on one end, and then appears to make a 90 degree turn into the engine block.

If any of you can figure this one out, I would greatly appreciate it. Thanks. George.

it could be as little as the waterpump gasket is cracked, or the pump itself has a crack in the casing. Definietely think positive, start with the little things, the easy fixes, see if that doesn't help.

What could be happening is your gasket on the TB might be going causing it to leak from underneath. Without a tight seal it will leak out of the throttle body too. If it is don't run the car because it will be sucked into your cylinders and you'll end up changing your sparkplugs because they'll be covered in oil and you'll need to crank the water out. Check into a tb gasket, it might not be the problem but thats what it sounds like to me. Why else would coolant be leaking from the TB?

Edit: I think i might of misunderstood your post, it's early in the morning, disregard the top if im way off.

I probably didn't explain that first part right. I didn't mean coolant is leaking from the TB, I meant when I rev it from the throttle body cable I can then see the small seepage from the crevise I spoke of. I cleaned that area with engine cleaner to see if it would get dirty again, and it's still fairly clean, so I dunno. I think it might be a gasket somewhere on the intake piece, or, maybe, in my Haynes manual where it shows a picture of how to remove the water pump on the 3.8 V6, that whole part of the engine is seperated, and it looks like right where my leak is coming from might be a gasket where that part piece the engine bolts on. Oh well, i'm gonna take it to an expert dealer mechanic my friend knows and he's gonna do the work on the side for real cheap. Thanks for the help, and you do seem to know your shiznit well.
