Help with coolant leak.

[dot45]

So car started overheating, drove a few minutes to parking lot at work. Popped the hood and saw coolant coming from somewhere under the power steering pump. Looks like from whatever the small rubber hose coming off the coolant manifold goes to. haven't been able to get under car yet. Idea's?

How much was coming out at the hottest part of the leak?

Once I got the car stopped (temp had reached the H, but engine light had not come on.) I'd say maybe half a gallon or so came out. It was not a stream, but fast dripping. Don't know how much fluid is in the system still. Over-flow bottle was full, but I've never had a car that would actually pull the coolant out of the bottle if needed.

Just got the Service Manual downloaded.

It looks like the hose is Item #14 on the attached image. What does that connect to?

Edit: Looks like the oil-filter-housing. (This could get interesting.)

Time for new water pump o ring and gasket.

Why? The issue is Part #14 (the rubber hose), not Part #13 (the o-ring)

Its hard to say yet..but judging from where its located and how much. Ide bet its the smaller hose..

Any idea on the size of that hose, I'd guess at 3/8" or 1/2"?

Factory Manual doesn't say..

I had to replace #10 and #15 on mine, they were both 3/8".

I'd definately rule out the hoses by replacing them before jumping to the water pump. Just go get like 3 feet of 3/8 and a box of clamps... sure, ones leaking now... but then the second or third will let loose down the road, preventative maintenance.

Thanks, I'll be swapping them all out. Just need to get it home first.

Let us know what comes from your investigation

Lets hope it's that easy.

Ya replace hose 14 which goes to the oil cooler first. But if that's not it suspect the o-ring on the crossover inlet pipe that goes into the water pump (water pump does not have to be removed). Especially if the water pump was recently replaced. It may be dripping down onto hose 14. Here's the problem: http://www.dsmtuners.com/forums/newbie-forum/309982-coolant-leak.html#post151625392.

Might as well do a flush while your at it. .

It was the rubber hose #14.
It is 3/8" hose.

Impossible for me to get to the bottom clamp without the car on a hoist.
The top clamp had cut into the hose and that's what the leak was, lost about 1gal. of coolant.

Got it fixed enough to get it home, putting it on the lift tomorrow to replace the hoses properly.

Thanks again for the help guys.
