The pump is the one below and rear of the ac on a 3.6L and is internal (timing belt) on the 3.5/4.0L
Its on the front of the engine. The pulley with the fan.
That pulley is part of the water pump. The water pump has failed and needs replaced.
That is the water pump pulley.
The pulley is pressed fit onto the pump. It will not come off the pump. You have to replace the pump to replace it.
The water pump pulley is the pulley right above the crank pulley (the big pulley in the bottom of the engine.) Right above the water pump pulley should be the alternator pulley, which drives the alternator. I'm guessing the water pump is behind the WP pulley. == == == ==
Gas engine, it is the part the fan is screwed onto. Diesel, it is just to the passenger side nd down from the fan pulley.
The water pump is driven by the pulley and serpentine belt on the left side of the engine. You'll need to remove the water pump pulley to access the water pump housing bolts. You may need to remove other pulleys to access the bolts. Replace the water pump gasket to prevent leaks.
Pulley above the crankshaft pulley (lowest on engine)
The pulley is part of the pump assembly. I don't think it comes off. The clutch fan unbolts from there. Is that what you mean?
The water pump uses the timing belt to spin the pulley on it. The pulley than propels the coolant throughout the engine. This keeps the cars engine at a moderate temperature.
Behind the Timing Belt at the front of the engine. The water pump pulley is the top central pulley on the engine. Removing the Timing Belt is required.
