Fan Clutch W124 by URO Parts

[Guyton Buzz]

Needed a fan clutch, old one was spinning freely when warmed up, when it should have felt like peanut butter inside. Boneyard clutch will usually have grime on the front, a sure sign that it has leaked out oil also. Bought this Uro Parts from a large online vendor, under $60.

Move the fan shroud back from radiator, reach in with that handy 8mm low profile ratchet, pull up on the serpantine belt to increase tension, and a sharp yank to break it loose. If you pull slowly, the pulley will turn. There is a handy spot on the back of the pulley for a special tool or some bent nose pliers to wedge and prevent the pulley from turning.

Note the little valve under the thermal strip. Some owners have re-filled it and re attached the thermal strip. 5 mm removes fan from clutch. Note that fan has the word "front" molded into it, the cupped side of blades goes toward block. The old clutch had extra paint on it, identity system for the junkyard.

My results were an improvement. Before, after an expressway run and stopping at a light I would see temps rise to almost 100 and drop back down. Now the change in temp keeps the needle of the gauge on the 8, moving a little across that number. Rad was new 3 weeks ago.
