He said one time he had a truck that would run great for hours and then just about die. I had an old mechanic today tell me to look in the tank really well. I'll look at them after I get my 8mo old son in bed. I never thought to check the air cleaners. It clears up really well and throws a little smoke when you get in the throttle but not black smoke. The truck smokes grey for about 10 min when you start it cold.

Repeat this procedure on the front section of the fan clutch. Loosen fan belts, rotate the pulley and feel for smooth rotation of bearings. Remove and plug airlines at the Fan Clutch input. Routine inspection of the Horton Fan Clutch should be carried out at 200,000km intervals. Is there a pressure drop causing partial disengagement? This usually is caused by an inoperative solenoid, airline blockage, up-stream air leaks, air leaks from the fan clutch body itself or low air pressure. Look for a problem that is causing partial engagement – usually, air leaking past the solenoid valve seals into the airline causing a pressure build-up. Clutch SlippageĪ fan clutch needs 100 psi (6.8 bar) for solid engagement. Check that there are no cracks or splits in the fan blades that might cause the fan to run out of balance. Check, locate and remove anything that may be an obstruction to the fan blade.

Fan Bladesįan blades should be checked for correct clearance to the radiator, shroud and engine components. Catching problems in the early stages will keep damage and downtime to a minimum. This protective action also alerts you that there is a problem, so you can troubleshoot and repair the problem immediately. When the System Sentry has released the fan clutch, it has done this to protect your investment. This allows air pressure in the fan clutch to drop, disengaging the fan clutch immediately. When damaging levels of heat reach the System Sentry the fuse will melt. This heat works its way toward the center of the fan clutch. In the event of fan clutch slippage, heat builds up at the outer edge of the Piston Friction Disc (PFD).

Conversely, on a long descent, a professional driver will manually activate the fan to help aid engine retardation because the fan soaks up 30 to 40 horsepower.

Most vehicles also have a manual override switch which will allow the driver to activate the fan on the approach to a hill to bring the engine temperature down. It disengages when the valve closes, allowing the clutch solenoid to exhaust air and let the spring return. The clutch engages and makes the fan turn when the valve opens, sending air pressure to overcome a spring and push the Piston Friction Disc (PFD) against the friction material. On older trucks, the signals are sent from the temperature sensor. On modern vehicles, the solenoid receives signals to turn on and off from the engine’s ECU. In this feature, we’ll explain how the Horton fan clutch works, what maintenance it requires and importantly what to keep an eye onĪ Horton fan clutch’s prime function is to engage and disengage the engine fan with a clutch controlled by an air-actuated solenoid valve. The Horton fan clutch has an important function in a truck’s operation, yet it is one of the most overlooked and least maintained components.
