Coolant leak

[bprince]

I have a coolant leak and I think it’s coming from the top of the water outlet tube. It’s the highest wet point that I can find. Anyone ever had a problem here or replaced one themselves or at a shop?

Are you losing a noticeable amount of fluid? A pretty known/common problem on these trucks is a faint coolant smell. I do see the mineral deposits coming out of that connection so it does seem that you have a leak. Just be sure that is actually coolant. In looking at that picture there is an outside chance the deposits are from something dripping off the pipe above (is that upper pipe part of the A/C system by chance?).

Yeah the only reason I knew to look is that I had two smaller puddles under the truck on my driveway. Saw fluid on the axle and just above and followed it up. Most of the posts I see is of the egr deletes. Mine is in CA and still has the egr and is stock. I read that if it’s leaking from the lower part then you have to replace that whole standpipe ($400-600), but I believe it’s from the upper one since there are the deposits on the top of the lower pipe. It is all coolant system from what I can see from the diagrams. I can’t find if it’s an o-ring up top or how that fitting that comes from the engine plugs in there.
