I need to replace the fan clutch on a 1993 Chevy S-10, 2.8 V-6. I have removed the fan cowling. Must I remove the fan as well or just unbolt the clutch?

On the 1969 Chevelle, there are only four regular bolts securing the fan clutch to the water pump. Start by breaking the four bolts loose while the fan belt is still on, but don't remove them all the way. (Makes it easier to break the bolts free without dealing with the water pump pulley turning). Once you have removed the fan belt, you can either unbolt the fan from the fan clutch first, or simply remove the fan clutch and fan as a single unit. JUST BE CAREFUL THAT YOU DON'T DAMAGE FINS ON THE RADIATOR IN THE PROCESS.

You unbolt the fan clutch from the water pump pulley.
Is that your question ?

since u removed the pump and fan assembly already place the pump carefully in a vice or some thing that will hold pump than use a strap wrench to hold the pulley and than unbolt the large nut it is a reverse thread so clockwise to loosen and counter clockwise to tighten

It depends on what engine you have and if it has AC or not. Some you unbolt the fan from the clutch 2.2 2.4 with on AC with AC you need to unbolt fan from pulley with the clutch 4;3 you have to remove fan and clutch at the same time by loosening the large nut that is threaded to the water pump shaft its right handed thread and thats with or with out AC

Just leave the belts on the engine and use a open end wrench,I think a 10 mm,might be a 8 mm,and use another wrench to hold one of the nuts,and loosen all the nuts,then remove them by hand.Of course the fan shroud needs to be removed at the same time you lift the fan and fan clutch up,and out of the vehicle.Then just unbolt the fan from the fan clutch,install in reverse order.If this was at all helpful,please rate,thank you.

Ok, it's best to have the fan belt ON all the way, that way it holds the pulley in place. Then, put your wrench on the nut, and tap the wrench with a hammer. This will break it loose, and then you can unscrew it the rest of the way. It works like an impact wrench.

under hood drivers side on fire wall between engine and brake master cylinder take off wiper arms slide tab at bottom lift off -- un- screw cowl the cowl is in 3 parts -unscrew center with hood closed first the screws are recessed about an 1-1/2 below the top of cowl open hood and unscrew the both sides of cowl and remove than remove center watch the washer hoses now will have access to the wiper transmission mark where transmission is before unbolting motor and transmission remove motor install is in reverse

The waterpump on a chevy suburban can be removed once you remove the radiator fan.

1. Drain the coolant from the system.
2. Here is a way to remove the fan clutch withouy a fan clutch tool. The trick is to leave the belt on and tight.
3. Take a 1 7/16 inch wrench and put it behind the fan onto the big shaft nut attaching the fan to the water pump. P
4. ut it straight up and crack it counterclockwise with a hammer.
5. This should loosen the nut.
6. After that just spin the fan off and the rest is easy.
7. Make sure you clean the old seal off of the engine. It is small and easy to miss.
8. remove the serpentine belt.
9. remove the hoses connecting to the water pump
10. remove 4 bolts holding the water pump onto the block
11. clean the block of any old gasket
12. fit the new waterpump and new gasket.
13. connect the hoses to the pump.
14. refit the serpentine belt
15. refit the fan
16. refit the rad and cowling
17. fill it up with coolant.
18. Run the engine and check for leaks.

yes because there isn't enough room to remove it through the bottom so u will have to remove the air intake going to ur air filter box and the water hose going to ur radiator and the fan cowling but u don't have to totally remove the fan cowling just unbolt it and the pump should fit. I did this about a week ago it was that hard either. But I had a stripped bolt so I was a pain to get to the bolt. I wound up cutting my bolt off and replacing it with a new one.

REMOVAL & INSTALLATION
Disconnect the negative battery cable.
Position a drain pan under the radiator, open the drain **** and drain the cooling system to a level below the heater core.
NOTE: Plug the heater core tubes to avoid spilling coolant in the passenger compartment during removal.


Disconnect the heater-to-engine coolant hoses from the core tubes on the fire wall, in the engine compartment.
NOTE: On some early model vehicles, the cabin light mounted under the dash may interfere with cover removal. If necessary, loosen the retaining bolt and reposition the light housing with the wiring attached.


From the passenger compartment (under the dash) remove the heater core rear case cover-to-cowl screws, then remove the cover from the vehicle.
NOTE: On a few of the early model vehicles covered by this manual, some of the heater core cover screws may be partially/fully covered by the dashboard. Be sure that all are removed before attempting to remove the cover. If necessary, unbolt and reposition all/part of the dashboard for better access.


Remove the straps or brackets from each end of the heater core.
Carefully remove the heater core from the cowl and case.
Installation is the reveres of removal. Run the engine at normal operating temperatures and check for leaks
