Hey all,
2013 GMC Sierra 2500HD, 6.6 Duramax LML, 4x4 etc.
The truck was loosing coolant and my diesel shop found a leaking head gasket. They replaced both head gaskets, heads were pressure tested, EGR removed and blocked off, truck is deleted, new water pump and t-stats.
I'm loosing coolant again and I don't see any leaks/drips anywhere. The same shop has pressure tested the truck for 2 days and driven it, etc. and can't find the leak. Any ideas?
