I've been looking for this leak for months. I found it but I dont know what it is. Anyone familiar with this.

Its a hose directly behind(lower right) the belt tensioner going into the intake.

 

That is one of the two (prone to failure) coolant elbows. Youre going to need an intake job. The thing that-that elbow is connected to and everything above it needs to be removed, gaskets replaced, and of course those two elbows. Look into getting the aluminum ones.

 

Dorman is the brand that makes the aluminum replacements. You can get them online or at any parts store.

 

Damn. Just as bad as I thought it would be. Thanks a bunch. At least I still have time to get in there and get it done.
Is there anything else I should replace while I got It apart?

 

Got it Done. Without rebuilding the intake.No longer leaking. Thanks again!!!! Replacing the mounts next, also the cooling fans. Gotta get my tranny rebuilt, soon. It's alot but I think she's worth it.
After all, She IS one SEXY LT.

 

Howd you get them without taking the intake off?

 

I have done that plenty of times. You just take the alt out and then the alt bracket out. Slides right out, may require a pry bar once in a while. I want to say it's about 10 minutes of work.
