replacing water pump

I bought a replacement water pump for my '88 f150 I6 from advance auto. The brand name is ASC, and it came with a gasket and a small rubber band about an inch wide - what is this for? Also, does this engine's fan/fan clutch assembly require the use of a special tool for removal? I am a novice at best but figured I could handle this one. Thanks, Jason.

Hi Jason,

I'm not too sure what that rubber band would be for. It will help a great deal if you have the special tool made for the fan removal. It is two wrenches together and I believe 1 5/16. I have gotten the damm thing off with a pair of large channel locks but it was not the easiest job like that, I remember I had to use a small amount of heat as well. Best hunt for this tool or borrow it from a local franchise. By the way it is reverse thread.

[updated:LAST EDITED ON 05-Jun-02 AT 04:40 PM (EST)]I ended up braking mine off and using a factory flex fan from my '81 instead of the whole clutch assy.

P.S. If you do that, you'll have to get different bolts (Same size (5/16-18) but much longer (2-1/4 or 2-1/2 or something))

Most Autozones or Checker Auto let you buy the tool, then return it after you use it. I just did mine the other day. I think mine was a 1 and 7/16 inch tool, but yours may be different. I'm a novice at some things, but I did fine after realizing it was reverse-threaded. In the Haynes book, it says, "Turn counter-clockwise to remove. Note: Some turn clockwise." What a bunch of junk! "Turn left, but sometimes right." ARRG.
Some benefits of do-it-youself truck repair:
1.instant gratification of a job completed
2.goo-bath when the coolant runs up into your armpit
3.grease treatment(keeps your arms from becoming dry)
4.exfoliation(when you scrub grease from your arms)
5.sweet treat(when you get a couple drops of coolant in your mouth while you're talking to your buddy from under the truck)

Thanks guys. I got it off this morning before work with a big crescent (after I removed the bolts holding the pulley to the water pump) and a little muscle.

One other question - when I removed some of the bolts holding the water pump on, coolant spilled out - I suppose the bolts run into the water jacket. Should I put a dab of sealant on the bolts (close to the head of the bolt - so the sealant doesn't end up clogging up something) or not? There doesn't appear to have been sealant on the bolts that I removed.

Thanks again.

Sealant is not a bad idea. Certainly won't hurt.

As for thread direction on fan clutch: V-belt driven fans have left hand threaded clutches. Serpentine belted fans are right handed as well as having fans that are pitched the other way. (Serpentine belted fans spin the other direction due to the different belt routing.) Whichever way yours spin, be sure to grease the threads of the new one and only snug the nut. It's nice to be able to get the buggers off again... And make sure the fan blade is facing the right way (it's labeled) as the blade is curved and pulls more air in the proper orientation.
