7.3 Water Pump Replacement
 

Does anyone have a link for the instructions on how to change a water pump on these engines?

Here you go Diesel-Central.com the technical source for Diesel Truck information, Truck Pulling, and Drag Racing
I just did this 2 weeks ago. Follow the instructions exactly and you'll have no problems at all.

No link but some useful info. PM me your email and I will send pics.

Replace all hoses, belts, and check idler/tensioner pulleys,thermostat

It was mentioned that the torque was high on the bolts listed on that site. “Blackjeep” noticed error. Don't snap'em.

The links don't work(lost in the conversion) but i attached a page out of the manual.

Thanks for all the responses. How long should this repair take to to complete? Keep in mind that I am not a mechanic, and I have only average mechanical skills.

I just did mine a couple weeks ago....took about 3.5 hrs, but that was with a couple beers thrown in there. Real easy too.

Good video a few pointers though:

1) The video called out 2 people special wrench (I covered this also) and a pipe wrench.

I did this with the special wrench only and 1 person. What I added was !@#$!@#%$@#$^^$ and it came of easily.:-hair

2) I removed the hoses from the attachable necks and removed them with the water pump.

3) I did not remove the hose neck at the thermostat prior to removing the water pump.

NOTE: I found on the first bolt it snapped off easily. The remaining 2 smacking with ball peen round end of hammer before attempting to remove prevented breaking. Don't know why they stuck. But mine did not come out as easily as the video.

4) I used the tinnnnest drop of super glue to hold the water pump gasket in place. Think pin head size. to prevent the gasket from dropping out during installation.

5) Check all pulley/bearings

6) Replace all hoses and please buy the upgraded hose that goes around the belt vs through it. This will make you life easier next time.

7) I also reused the thermostat due to not having the correct one to install. I would recommend buy the factory part for the 7.3 thermostat.

:-drink

I used a visegrip style chain wrench 19" IIRC to hold the pulley, and a small pipe wrench on the nut. It is about a 3 hour job.

I used Syl-Glide silicone lubricant from Napa on the o-rings and the pump gasket. The Syl-Glide's tackiness held the pump gasket in place.

Good suggestion!:-drink my Napa was 20 miles away and I was working alone.

Just a thought if you havent gotten a water pump id go with the Napa new tru flow pump part # TFW 45000. Its the best ive come by and its a one piece design so no more leaking lower neck. For what a t-stat and gasket cost change them! http://www.napaonline.com/NOLPPSE/(S(wgeyqgio430buk55ahm2fn55))/Detail.aspx?R=TFW45000_0144865560
