How to turn engine over manually on Mercedes-Benz C200 W203 kopmressor 2001
The car has mixed water and oil in the engine. I found water in the air intake manifold ( which i have removed already) there was also water in the exhaust as i remove it from the manifold. Serpentine belt is removed and the spark plugs including the radiator for space purposes but its seems hard to manually turn the engine over. Should i use more force? I need help!
