Water Pump roadblock.

I’m about to get rained on, so I’m gonna have to pause for now. However, photo update.
I plugged that hole because I didn’t want any dirt and grime getting in there when I put some degreaser on there and wiped down a few times.

I’m curious; I just got off the phone with my Dad, and he suggested I keep the old pump and ask about rebuild kits and if anyone had success with them. I know the FSM has overhaul kit part numbers and such…

Absolutely follow this guidance. Last 3FE water pump I installed I had to do it twice because the new, out of the box, Aisin pump leaked.
😵‍💫 Roger that…I briefly discussed this with CruiserMatt too; and I figured it might be better for me to be safe than sorry. I really don’t want to this twice over LOL.

Second time is quicker, easier, and a good learning experience.

Kudos on purchasing from one of the specialty vendors in the LC “scene”. You don’t get phone support ordering parts from Rock Auto or Amazon or whatever. It keeps the money in the community and you have a knowledgeable person selling the part. Win win. Go to the vendor section and the small business section (in the classifieds forum) and you’ll see how many folks are out there doing stuff to help these trucks keep living.

Agree with the above comments on the JIS screwdriver: Vessel is the brand you want.

You can also get real crazy and start buying high end Japanese socket sets too. Not necessary unless you’re a madman though. Some of us are. I have a cheap metric Craftsmen set that’s taken all the abuse I can throw at it and it lives in the truck for emergency repairs. I have a nice, and wildly unnecessary, Koken set for the shop.

Heed Godwin’s advice and take that backing plate off and seal it up. Doesn’t have to be a lot of sealant. I didn’t know about that and I got real lucky - the WP I installed a few years ago didn’t leak. But there’s lots of horror stories here on Mud.

There’s a place that rebuilds smog pumps - BZ Rebuilders in Canoga Park CA (LA area). I’m pretty sure they do WPs too. If not, I was recommended this place but have never used them: Better Than New - http://water-pump-rebuilders.com/better%20than%20new.html

You’ll find with these trucks that you’re gonna be utilizing a lot of “down home” or “old school” type shops - like the place above - for things. Parts availability is dwindling and we need to turn to the keepers of the old knowledge while they’re still alive.
 
It's not really worth rebuilding these water pumps at the moment because there are still quality pumps available even though the OEM pump is now discontinued.

Any of the parts listed in the FSM for a water pump rebuild are long discontinued and are generally unavailable.

That being said, I would keep the old core cuz you never know what's going to happen in the future.

In the picture above, it looks like you've got some debris in the holes for the water pump bolts. Good idea to take a can of brake cleaner and spray them out.
 
I totally agree with all that @Spike Strip said. Get a new pump but keep the old one. And do clean up those threads.

To the last bit, yeah some of that debris got in there when I did the first few degreaser wipes. Is it okay for me to just spray in there even though it foams up?
 
Yes, spray anything you have into the holes to clean them out. Brake cleaner, WD40. Compressed air - even a duster can you use on your desktop keyboard. You just want them clean and debris-free so you get an accurate torque reading. You plan on using a torque wrench, yes?. Brake cleaner works best for me.

Use a spot of anti-seize on the bolt threads when re-installing. I personally coat the entire bolt with a thin film of general purpose anti-seize.

Also, if you're reusing the old fasteners, wire-brush or wire-wheel the threads to cleans those up.

Got it. I can do that; and yessir, I have a digital torque wrench.

I’m using brand new everything for this job, but I’ll definitely go buy some anti-seize.
 
Clean those threads out real well as Spike Strip said and clean up the mating surface too.
If the bolts don't thread in smoothly consider carefully chasing the threads. Then flush them again.

Here's the water pump backplate removed with FIPG added for your reference.

If you are careful with the removal of the plate, you can reuse the gasket.
Hope this helps. Keep the wrenching up. It will be worth it.
 
Just my .02 on chasing existing threads: A tap can sometimes be too aggressive and remove material you don't want removed. Depends greatly on the quality and type of the tap. I much prefer to use a quality Thread Chaser which just cleans up existing threads. This set was recently reviewed on YT and found to be the best 'Value'. USA made. You will find all kinds of use for it with a 40 year old vehicle. I bought the Snap On version before I knew Snap On just rebranded the Lang

Agreed. That is a great kit. Going to add this to the tool box!

Lang has one that both SAE and Metric of you have need for it. I used my Snap On kit so much, I had to buy a Lang Metric set to replace the worn out M8x1.25 and the M10 male chasers. The female chasers are amazing for fixing buggered bolts and studs.
 
I hope to have an update this upcoming weekend when I’m not working and can finish up. I just got the sealant today from @cruisermatt and I should have a set of Vessel screwdrivers delivered tomorrow.

I’m honestly considering to buy this as well…partly because I’m not satisfied with just “bare minimum”; and I am in no way suggesting that cleaning up the threads with the aforementioned brake parts cleaner or one of the pressurized air canisters is as such (I did BOTH methods last night after work), and that leads into the other reason. I don’t want to do this truck a “disservice”. If I know I can do “more” or “better”, why not.

You’re gonna go far kid. Just keep the stamina up because there’s about 15 projects like this waiting in line behind the WP.
