This is a Nissan engine model K21 aluminum cylinder head and plastic / aluminum PTR radiator off of a Clark forklift that came in for repairing and rebuilding. The cylinder head was completely disassembled as well as the radiator. The cylinder head was completely boiled and sandblasted inside and out while the radiator was boiled out in the hot tank and ultrasonic before getting all of its tubes rodded out. The cylinder head then received a complete three angle valve job and surface before the new positive viton valve stem seals were installed onto the valve guides. After the new valve stem seals were installed the cylinder head was assembled and then vacuum tested to make sure all the valves are seating on their respective valve seats. The radiator was put into our PTR jig and the plastic tanks were reinstalled to the core with new rubber gasket seals. After the radiator was assembled we pressure tested it in our test tank to ensure it has no leaks. For all of your machine shop and radiator shop needs please give us a call. We are a complete and fully equipped machine and radiator shop located in Las Vegas, Nv.
