Got Diesel? The 1st pic is an ISX Cummins cylinder head that came in to be checked out. The 2nd & 3rd pics are of an Isuzu 4HE1 diesel cylinder head that we built up for a customer that had a cracked cylinder head. We had to make that coolant pipe sticking out of the head as well. & the last pic is a Caterpillar 793D haul truck radiator in the test tank under pressure test. Thanks for looking & have a great weekend!!
