matslp488 Posted February 24, 2021 Report Share Posted February 24, 2021 Yesterday after getting home from work and letting the truck sit for a while I noticed a small puddle of coolant under my truck... I gave it a quick check but couldn’t find anything obvious.. only thing found was that it leaks down onto between engine and where the tranny meet so I checked both hoses that go into the firewall for the heat condenser but those seem ok...any other suggestions?? Thanks! 05 SS Quote Link to comment Share on other sites More sharing options...
someotherguy Posted February 25, 2021 Report Share Posted February 25, 2021 I'd ask over on PT for more traffic and eyes on your question. I can't think of what might be leaking at the rear of a 6.0 except possibly intake gaskets? You had proper antifreeze concentration in the system so no potential for issues with that shit weather we just had? Richard Quote Link to comment Share on other sites More sharing options...

matslp488 Posted February 27, 2021 Author Report Share Posted February 27, 2021 Thanks guys for the suggestions... I have checked and checked I everything points to be the intake gaskets... I haven’t driven the truck in a while to prevent any major damage.. it’s just parked waiting for me to start working on it... truck is filled with coolant so the cold weather wasn’t a factor..

TPeerson Posted March 1, 2021 Report Share Posted March 1, 2021 It's an easy diy fix. Take you about 2 hours Quote Link to comment Share on other sites More sharing options...
matslp488 Posted March 29, 2021 Author Report Share Posted March 29, 2021 Found my problem... 1 side of the coolant crossover pipe on the rear side of the engine was leaking from the o-ring gasket... I bought the replacement felpro gaskets that have 4 and replaced both rear ones and front ones since I was there already... pretty simple and cheap fix... trucks been good ever since... hopefully someone finds this useful in the future 👍🏼 1 Quote Link to comment Share on other sites More sharing options...

It's easy for people to overlook these crossover pipes. I chased this for a bit too. Never leaked fluid to the point it would show up, but I could catch the scent of hot coolant from time to time Quote Link to comment Share on other sites More sharing options...
