Q&A

You may have blown a head gasket and now one cylinder is full of coolant. If your engine still won't turn over with a good battery first remove the serpentine belt. If the engine turns over with the belt off then one of the accessories has seized. If it still won't turn over try rotating the crankshaft by hand with a wrench. If the engine turns over by hand the you have a starting system problem. If it won't turn over by hand then remove the spark plugs one by one and note if coolant comes out of any of the spark plug holes. If you find a cylinder with coolant then try turning over the engine after removing that spark plug. If the engine turns over the you have found the problem cylinder. If more than one cylinder is affected then you may need to remove all the spark plugs.
