Hi All, With reading various threads and searching down a problem of my own I noticed there wasn't a good thread on fan clutch replacement with pictures. I did read a lot of posts and people were complaining about this being the worst job they have ever done and it's really not all that bad.
Tool List:
Notes to remember:
Be careful maneuvering the fan clutch and shroud near the radiator. You can easily damage the delicate cooling tubes in the radiator if you hit them.
When reinstalling the fan clutch to the water pump make sure you thread it on by hand to start and keep it properly aligned while threading. The threads on both the water pump and fan clutch are very fine and easily damaged.
Wash off all spilled anti freeze prior to starting your vehicle. Failure to do so will cause the serpentine belt to slip and squeal.
Top off anti freeze when complete allowing the engine to run, thermostat to open and air pockets to burp.
Comfort and ability to do this job: Low to medium
Time to complete: 1 Hour.
#1 Before renting or buying a bunch of worthless specialty tools. Hit your local tool supply store for this wrench. About $12 at TSC.
#2 Removing your radiator upper core support. 8 Bolts 6 13MM and 2 10MM. A couple different views.
#3 Remove upper radiator hose. They make a specialty tool for the spring loaded hose clamps, however a good quality pair of slip joint (Channel Lock) pliers work fine. Rinse down your spilled anti freeze with water!
#4 Disconnect electrical connector to fan clutch. A few different views.
Simple squeeze of the tab to release. There may be a lock clip to remove, mine didn't have one.
#5 Loosen and release fan shroud. THE FAN SHROUD IS NOT REMOVED YET! That will happen later! There are 2 10MM head bolts at the top corners of the shroud, Two rubber flaps on the sides. and the transmission oil cooler lines on the back face. The rubber flaps are just pushed on to (2) nipples on each side. The long pry bar helps reaching and releasing these flaps. The transmission cooler lines are clipped into the shroud another place to use a prybar to pop them out. When they are released push them down below their retainer.
This first pic is the same as the missing radiator hose. If you look below the neck you'll see one of the tabs where one of the 10mm bolts is fastened. The other tab is simply at the opposite end of the shroud.
The rubber flaps on the side of the radiator were impossible to get pictures of while the still assembled. So the following pictures show the left and right sides of the radiator with the flaps after the shroud is removed. If you look closely you can see the two holes in the rubber flaps where they attach to the tits on the fan shroud. The two tops of the flaps would be easier from above the truck reaching down. The two lower parts might be easier from below, reaching up. THESE ARE HERE FOR A REASON, PUT THEM BACK WHEN YOUR DONE!
The next couple of pictures show releasing the transmission lines from the fan shroud. Push the lines down below their retainer so the shroud will clear them when you lift it out.
#6 Loosen and remove the fan clutch from the water pump. This is where that 1 7/16" wrench and hammer come into play. Put the wrench on the large nut attaching the fan clutch to the water pump and 3-6 good hits with a hammer and the clutch loosens its grip. The clutch loosens counter clockwise, Look at the picture! After the initial grip is freed you can spin the fan and clutch off the water pump by hand. After its loosened completely push the fan clutch forward to clear the water pump and lift it up and over the top of the water pump pulley bolts.It can rest there until you're ready to remove it and the fan shroud together. The fan is integrated into the fan shroud. THEY MUST BE REMOVED TOGETHER. See next step!
