Volvo Penta,TAMD 74 PB, 2002
(Miami, Florida, USA)
Ever since I had cooling system flushed, heat exchanger descaled, raw water pump replaced and new coolant added the engine spits coolant from the overflow tube. When filled to approximately 2 inches below the top of the fill tube (as per Volvo Penta) it spits more. After the level has gone down some it spits less. But it always spits. Engine does not overheat and runs well. Radiator cap has been replaced. This is a recent problem following described work.
