Guys I I need help ,I have an 04 it was a theft recovery and they drove it like they stole it . Fast forward to now have a newer shop redo the heads,went to go fire it up coolant pouring out the band clamp under the truck.I pulled the glow plugs and antifreeze shooting out all 4 glow plug holes while cracking How the hell does antifreeze come out all 4 cyliders??? ARPS new c gaskets check the deck for flat before bolting the heads down my screw in injector cups .....I mean the head has to be bad right?
