Re: Cooling fan

The fan has an electro magnetic clutch which cuts in when the engine reaches about 100 degrees.

Before it gets to that temperature, it will spin slowly, but this is just caused by the draft made by the pulleys going around.

Check to make sure it kicks in when the engine gets hot.

When you say newly repaired engine, has the engine had a full overhaul[?]

If so, then keep the revs down for the first 2000 miles or so and monitor the oil and water levels for the first 2 weeks.

electro magnetic clutch

My mechanic says that the "electro magnetic clutch" or coil is not working and has to be replaced. It was working before the engine overhaul, what could be the caus of "electro magnetic clutch" failure?

Re: Cooling fan

If it was disturbed during the engine rebuild, it could be a broken wire, but it is a sealed unit so you can't check that.

I am assuming that your mechanic has checked the fan switch (coolant temperature sensor), because I would have thought its more likely to be this which has gone faulty.
