[rparlaman]

Does the clutch fan come on when you drive it for the first time when cold,or sometimes you don`t hear the roar of it? Mine used to do it and i noticed it does not do it anymore/ Need some help

Watching your A/C pressures with a set of gauges

Is a way of testing your fan clutch,because 134 freon pressure reacts drastically with air flow across the condensor or the lack of it. Get your truck good and hot with the A/C on hook the gauges up and watch the pressures at a high idle about 1500rpm. If the fan clutch keeps the pressure down below 250psi. If it rises over 300psi it is having problems. Assuming everything is well with the A/C system.

You should hear it. Is there dirt on the front of the fan clutch? If there is dirt/oil/dust on the part in the center that looks like a flat coil spring, it will have negative effect on it.
