i have an 87 190E 2.3-16V. while the engine is running, the fan is moving much tooo slow. i can put my fingers on the fan and hold it and it stop moving in a still position. does this mean the fan clutch needs replacement? or which other parts? the belt moves fast, but the fan spins very little. there is no overheating problem, well at least for now. any advice would be helpful and appreciated.
thanks in adv....
