Oil in the Radiator! Top End Internal Tear Down! GM 3800 3100 3400 3.8 #mechanic

This is a 2002 Pontiac Firebird with the GM 3.8l 3800 Series II Engine. This vehicle came in with an large oil leak on the engine and an oily substance in the radiator. The antifreeze was mixing with engine oil. The problem is common with this series of engine. The lower intake manifold gaskets deteriorate and case coolant to leak into the engine oil, oil is also allowed to contaminate the cooling system resulting in the fouled coolant and soft radiator hoses. This is multi part repair and is somewhat difficult in this particular car due the firewall and wiper cowl location. We will remove the intake plenum and lower manifold valve covers, and the engine accessories such as alternator, belt, and the tensioner. In this case the belt tensioner also has a heater core bypass built into it so there is engine coolant in the belt tensioner as well. Part one will be the teardown, part two will be engine assembly and the final part will miscellaneous assembly, fluids, cleaning and final inspection. This video is part one of this series. As mentioned in the video this vehicle was featured before due to catastrophic A/C system failure. See links below for all past videos.
