Recently completed 2011 Chevy 2500 LML in for a coolant leak diagnosis which unfortunately was caused by the worst case scenario, excess cooling system pressure due to a head gasket failure. This truck received a pair of centerautomachineshop O-ringed heads, and a set of ARP head bolts for added reliability and peace of mind!

We have seen our share of CP4 failures come through the shop over the years but this one is just impressive! This one came out of a 2019 6.7 powerstroke, unfortunately before it blew apart it did have a “Disco party” and contaminated the rails and injectors with debris. The truck received a complete fuel system along with an DCR conversion and back out it went.
