4.8is Passenger Side coolant leak

[thrillcat]

A few weeks ago I had it in to have the valley pan and pipe replaced.

A couple days ago I noticed a small puddle on my garage floor, passenger side, behind the front wheel.

Tonight I noticed it dumping a ton of coolant after a 15 minute drive looking under there the entire suspension and inside of the wheel are soaked. Looking from the top, the MAF and all that housing were dry, but it looked like the leak was coming from whatever is directly below that, or from the bottom.

I've tried searching but everything turns up the expansion tank (other side) or the valley pan (just replaced). Ideas? Could they have screwed up on the valley pan?




Looking down:


Thanks.

Highlighting the spot under the MAF...

Isn't the tranny cooler located down in that corner? I'd suggest getting it up on jacks and pulling off the lower covers to get a better look. If it's that cooler, hope the crack is only on the cooler part side and the two aren't mixing. If it's on the coolant side only, fix it quick, before it leads to tranny heating issues.

when I was getting my seals replaced on entire car this winter ($5k job) the guy recommended I get a ANTIFREEZE seal fixed that leaks a lot of time.. i suspect this might be this part you did not get replaced ... because it leaked in the same freken location just not as bad.. a few drops a night.. i had to fill up on coolaant every 2 months.. after seal was fixed i did not have to top off coolant in months

Turned out to be a hose that connects across the front to a distribution block. Hose ordered. Should have it back tomorrow.
