I`m changing the water pump in my 1999 dodge ram 1500, but I can`t lose the fan nut that is attach to the water pump.please help.


Those fan nuts are just tough to get off, however it may have "left-hand" threads. If you can see any threads, look straight down at them...if threads are going "downhill" from right to left, then they are common right-hand threads, Lefty lucy-Righty tighty. However if the threads are going "downhill" from left to right, then they are left-hand threads, and you will need to turn the nut "clockwise" to loosen it. Hope this helps....let me know either way!!

Replacing water pump, how doers the fan come off the pump shaft. It looks like it's screwed on with a large hex nut but how can I loosen it without the shaft turning. Frustrated


The fan clutch is threaded onto the water pump. They make a tool to hold the pulley from turning so you can turn the large hex part of the clutch. You can probably rent one for free from a parts store like autozone or the like. Keep in mind some clutches are left hand threads also keeping the belt on the pulley also helps the pulley from spinning also.

Removing fan to replace water pump on 1994 318is bmw


Not sure if it is the same, but I have a 1996 328i and the fan is attached to the front of the water pump via a large nut. That nut is a 32 mm (1 and 1/4 inch fits it as well), and is BACKWARDS threaded (i.e right to loosen and left to tighten). You may need to use a pair of vise grips and lock onto the belt to keep the entire front of the motor from turning. I have also heard giving it a few good whacks from a rubber mallet tends to get them to break free. If you do have to use the Visa grips on the belt be careful to not break your water pump pulley. Although it looks to be made of metal it is actually made of plastic and will break if it gets caught up in the tension of turning that fan nut. When the motor is running it is turning in the tightening direction, so I put some anti-sieze on the threads before re-installing. Hope that helps.

Remove water pump have removed outer plastic blades of viscous fan and the four small bolts behind the water pump it seems loose but will not come away, is it just the internal impeller blades dont want to...


what's up led, the large viscous nut is loosened in the clockwise direction. after you remove the 4 nuts on the water pump, you should see one hole on each side of the water pump body. if you take 2 bolts out of the thermostat housing, you can use those to thread in the pump body holes.slowly tighten each bolt equally and the pump should come out. to install a new pump, lubricate the o-ring on the new pump and just push in by hand.

How do I remove the fan assembly from the water pump on a 2003 chevy suburban?


You'll need a clutch fan wrench. It's a thin, large open end wrench that is available at most part stores. Place the tool over the large bolt that holds the clutch fan to the water pump and give it a quick hit similating an impact gun. You may have to do this a couple of times, but the clutch fan will come loose and simply unscrew it.

Fan removell


The big nut is part of the fan it threads on to the water pump. To remove loosen two of the pulley bolts put a pry bar between these two bolts the use a large wrench on the big nut to thread the fan off the pump. righty tighty, lefty loosey. They also make tools for removing the fan clutch.
