Belt Driven Fan Replacement Kit for the Porsche® 928
aka: Viscous Clutch Fan Replacement Kit
The Problem: Many of the old viscous-clutch fans are starting to fail in the field as they get on in years. The seals dry out, the silicone fluid inside leaks out, and then the fan either seizes up or pinwheels. If it seizes up, you are losing gas mileage and HP. If it pinwheels, you will see your temp gauge climbing when stop-and-go driving. Even when they were working, they barelay turn at idle - and that is when you need them the most when stuck in traffic.
Technology has improved since these were built, and we can now do better.
The Solution: This Kit will replace that old, inefficient fan with a new electric 2000 CFM unit that will keep your 928 engine cooler on the hottest of days... and save you gas and HP too!
You have Two Choices:
- The Standard Kit: This kit uses a heavy-duty thermal switch in the upper radiator hose to turn the fan on and off. The switch comes mounted in a billet-aluminum fitting, simply cut the hose and clamp in place - the switch is already pre-set to turn on when the coolant reaches 194 degrees. We also provide a relay and the small wiring harness you need. Install according to the easy-to-follow instructions provided and you are all done.
- The Electronic Controller Kit: Just like the kit above, except the thermal switch and relay has been replaced with an electronic fan controller. This allows you to set the temp where your fan turns on and off (between 160 and 240 deg F), and it buffers the fan start-up to help not blow fuses. Also, you have only to insert the temperature probe into the fins of your radiator to make it work, so you do not have to cut your radiator hose like before.
