You can take off the 4 bolts that hold the fan on the water pump pulley carefully and you won't need to take off the pulley. You may be able to do that without removing the fan shroud, but it will add a difficulty factor if you don't. Take out the fan clutch with the fan blade still bolted on. Separate the fan blade from the clutch and install the fan blade on the new clutch unit and re install it on the engine .

Let the vehicle run at approx 2000 rpm (standing still) and check the heatgauge. When the needle gets near the max mark you sould be able to feel the fan blowing air. Switch off the vehicle and feel if the fan is solid or not. You can use a standard blade, will have very small effect on feul consumption and power.

I don't have experiance with this exact model, but all the bolted on fan blades that I have removed f required removal of the belt; then remove four bolts on the front of the fan located in the center of the fan blade

yes its a velocity fan pulley that is driven off the cars pulley system. will eventually stop working causing overheating problems

* Fan operation can be checked by spinning the fan by hand.
* A noticeable wobble or any blade that is not in the same plane as the rest indicates that replacement is in order. The fan can also be checked by removing it and laying it on a flat surface. If it is straight, all the blades should touch the surface. Never attempt to straighten a damaged cooling fan. Bending it back into shape might seem easier (and cheaper) than replacing it, but doing so is risky. Whenever metal is bent, it is weakened.
* Fan clutches use a fluid-filled chamber (usually silicone) to turn the fan. Obviously, loss of the drive fluid will render the fan useless.
* One of the simplest checks is to visually inspect the fan clutch for signs of fluid loss.
* Oily streaks radiating outward from the hub shaft mean fluid has leaked out past the bearing seal.
* Most fan clutches offer a slight amount of resistance if turned by hand when the engine is cold. They offer drag when the engine is hot. If the fan freewheels easily hot or cold, replace the clutch.
* Another check that should be made is to push the tip of a fan blade in and out. Any visible looseness in the shaft bearing means the fan clutch should be replaced.
* Fan blades are balanced at the time of manufacture but can be bent if handled carelessly.
* Likewise, fan clutches are machined very accurately to run true. However, rough handling at the time of pump replacement causes nicks and dents on the mounting faces. This can cause the fan blade to be installed crookedly. Serious trouble might follow soon after the car is back in service.
* Therefore, handle fan clutches and blades with care and be sure to file away any nicks, burrs, or dents someone else might have caused. Obviously, if any fins have been broken off the fan clutch, it must be replaced.

You should remover the fan blade first the the fan clutch. Both have four bolts attaching to each part
