CUMMINS 8.3 litre DIESEL ENGINE HEAD GASKET REPLACEMENT...Removing accessories

This Cummins 8.3 diesel engine is in a Thomas school bus so accessibility is different compared to working on a highway truck. The Cummins 8.3 head gasket here is leaking down the back of the engine, so draining the coolant and removing the piping and hoses is the first step. The coolant drain petcock is located at the bottom of the engine oil cooler. This will drain enough coolant to allow removing the head without massive coolant loss onto the shop floor. The turbocharger can come off next, remove exhaust, charge air and intake piping then oil drain hose, oil pressure line and 4 retaining nuts. All diesel engines have turbochargers to supply boost air to the intake system, this particular unit is a HOLSET model, typical for Cummins diesel engines.
