I cant find a step by step how to remove water pump for 7.3ltr 2001?
can someone help please?

 

Haven't had to do it yet, maybe a Chiltons manual? Sorry not much help. But here's a bump.

 

YouTube - 7.3 WATER PUMP INSTALL 1 OF 8 FORD POWERSTROKE DIESEL

This is video 1 of 8 on water pump replacement on a 7.3, I havent watched them, but it may be usefull to you. Good luck.

 

First thing,to get the Fan clutch off. It was a pain for me,the threads are backwards. After you get the fan clutch off,its kinda simple. I think there are like 6 or 8 8mm bolts that hold it on,before you take the bolts loose,take your belt off. There is a place to put a 1/2 breaker bar/or ratchet to release the tension on the belt. After this, take your hoses off,then the bolts. I got mine at Oreilys $99.99 plus the core. And its lifetime replacement. I may have done mine the hard way,but I took my radiator off plus the fan shroud ,that way it gives you more room to get in there. You will have top,bottom and 1 heater hose to take off.....I also let the air out of my front tires,alot easier to get to everything,instead of laying on the radiator support.....

I just watched all the videos linked above, very nice!
They splain it all.

 

You've got an unusual one, then.

Most all of them are standard, right-hand threads.

I had to use an air chisel to get mine off. Had to take off the fan shroud. It kinda sucks, but doesnt take too long.

 

If you get the removal tool it makes getting the fan off alot easier. I fought with mine for a while and then got the tool and got it off in like 2 minutes.

 

There's a LOT of mis-information out there about reverse threads on the fan clutch, even my "diesel mechanic" told me they were reverse. My Haynes manual say's they are normal threads, and I can assure you they are (after I replaced mine a few months ago). Turn the nut counter clockwise to get it loose. (Scott, not sure why your's was reverse, that's very strange) I used a big wrench on the nut and left the belt on (I was changing it anyway). Give the wrench a few whacks and you'll get it loose. You should be able to spin it off by hand once it's loose. Be careful not to damage your radiator when it comes off, it's a little heavy and a tight space.

The rest is pretty straight forward, just take the hoses off and remove all of the bolts. Pay attention to where they came from, they are different lengths. When you put your new pump in, torque all of the bolts evenly. There is some bad info on a pump replacement web site out there too, it stated something like 40 ft-lbs of torque on the bolts, this is VERY wrong. I believe the correct torque is 18 ft-lbs. I'll have to re-check my manual for this.

Lastly - it's your call, but I'd at least replace the lower hose while I was at it. If you have to replace it later, it'll be after you lost all of your expensive coolant. :-)

 

I took my radiator and shroud out first,made it lots easier
John and Pop seem to have the rest covered

 

I have a 2001 and it had left hand thread, if I remember right. It was as the Haynes manual stated?

 

I'm not sure what's in your Haynes manual, but here's the front cover and page 3-5 covering fan clutch removal from mine. Since 2001 is in the middle of the range from 1999-2003 I would find it odd that Ford made a few with reverse threads (not impossible, just odd). If that's the case you're going to have a hard time when you go to the auto parts store for a new pump.

 

if the fan nut had left hand threads it would loosen its self and fall off
a whole bunch of stuff would have to be changed to have left hand threads

 

CRS must have set in early for you.
I have a 2001 and changed mine out twice already. It is right-hand threads. I didn't read it anywhere. Just know from experience.
