      Comments about Dorman - OE Solutions Electronic Radiator Fan Clutch:

      I decided to replace the fan clutch as my old one no longer spun. Installation was a tad difficult. After exactly one year it died on me along with an overheated engine. The fan didn't move at all. Luckily it has a lifetime warranty.

      Comments about Dorman - OE Solutions Electronic Radiator Fan Clutch:

      This is not a review so much on the product as it is on the specs. Does not fit all 4.2 Vortec engine. Be sure to check the large bolt (on the end of the long neck) is the same shape, thread type as the one you are replacing. I had an OE i was replacing and it had a different bolt than this one.

      Comments about Dorman - OE Solutions Electronic Radiator Fan Clutch:

      Was in stock, lifetime warranty but I pray I never have to replace it as GM did us no favors by engineering a one-piece fan shroud forcing removal of too many other parts in order to gain access.

        The Dorman Fan Clutch is a quality product. Just a pain in the butt to install because of all of the covers and braces needed to be removed to access the original fan.

            Drain some coolant or just remove the upper radiator hose - you need to remove the fan shroud and fan/clutch assembly at the same time. Start by removing the clutch from the water pump, then pull everything out together. The part went on easily and works great.

                    A:

                    Hi Doug, glad to help you! A bad fan clutch will create overheating of the engine and will cause the fan to not operate as it should. An engine fan not doing its job can increase the temperature in the engine, leading to potential engine damage. Also, a failing fan clutch can actually cause the engine fan to become loose and wobble and it can be heard while driving, especially at freeway speeds. A fan clutch that is going bad can cause the fan to not spin as quickly as normal. However, I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

                • Q:

                  Installed this new fan clutch assembly in my 2005 TB. Had clicking noise at idle and was suggested to follow TSB 05-06-02-004 which recommends reflashing the PCM with updated software to correct fan relay sequencing on and off at idle to maintain 500 to 600 RPM. Did reflashing and it appeared the condition had been corrected. However, after driving it about 250 miles it started doing it again.

                  Any suggestions?

                  With the fan clutch going bad, will the water pump go bad also? And how do know the water pump is bad?

                    Could possibly cause that. You will notice that the water pump has failed by it leaking out of the weep hole or by your car overheating.

                    The clutch going out could cause the engine to overheat when the car is idling at a stand still. It really would cause a weird sound.

                    Yes, I had my Trailblazer in the dealership because I was hearing a faint "siren" under the hood. I thought I had 911 under there. Anyway, the service tech told me that it was a problem with the fan clutch. They replaced it under warranty. You need a special wrench to remove the old fan clutch. It sometimes sounded like a "jet engine" shutting down.

                    Hope this helps
