Driving The Other Day And Kept Smelling Coolant. When I Got Home I Got Under The Truck And On The Passanger Side I Can See Coolant Leaking From The Head Gasket Down The Side Of The Block!!! I Cant See Much On The Other Side But I Hope The dealer Will Replace Both Sides For Such A Major Job. My Hd Only Has 28000 On It Injector Rates Are Good Always Below 1.oo Except #5 It Always Around 1.75 - 2.20. Has Anyone Seen This Is It A Common Problem?

First make sure it's not a simple leak running down along the crevices coming from somewhere above like the turbo coolant feed.

We have not had any dmax headgaskets in our shop yet. Like Hoot said, very possible for it to be from something else and running down. If it is the headgasket, they will not replace both, only the leaking one.

It could be the rubber coolant hose going to the turbo, which is on the passenger side, I've seen that one leak a few times. Only done one headgasket myself and it wasn't an external leak.

I had a leak one time on a 6.2L. It looked like a cracked block (oh no)! Turned out it was a hose and the coolant was finding it way all the way to the bottom of the engine before it showed up. CHECK CAREFULLY!!!!!!
