Changing out water pump and associated hoses and I’ve run into a snag. Getting frustrated trying to remount the water pump. I attached the hoses loosely to keep them in place but the smaller water pump to oil cooler hose bracket keeps getting in the way. Does it mount to the back of the harmonic balancer?
Fj60 water pump help.

But next time you’ll do it faster!
I'm currently replacing my WP and while I'm not having the same issues as the OP, I'm having a hard time attaching the two hoses highlighted in the picture - It's the pipe to the lower oil cooler pipe and the larger hose that goes to the lower radiator. I thought I'd be able to put those hoses on first but trying to fit them both on while lining up the WP was tough. In the process, I hosed my gasket.
So did I get it backwards? Should I be attaching my WP first and then those two hoses? If I do that, I'd have to take the AC compressor out. Currently, I removed my alternator and left my radiator in. Is the proper way to remove the AC compressor as well and then add the hoses to the WP after it's on? I think so but need some MUD guru confirmation (1st timer here). I also saw red hi temp RTV on the tstat housing but none on the WP gasket. I've searched and see that half of you put RTV on both sides of the WP gasket and half doesn't.

Been a while since I've done this but you should mount the WP first. Then attach hoses. Long screwdrivers will help. I don't recall having to remove the AC compressor. But it is a tight spot for sure getting to those hoses. Also try turning and pinning the hose clamp with one screwdriver or long handled pliers and tightening with another.
Just did this on mine last week. I like to use this product from permatex when installing paper gaskets. Used it multiple times on water pumps and thermostats and have yet to have one leak. Definitely helps hold the gasket in place when working in tight spaces.

Also, I did slide the lower oil cooler hose (15777 in the diagram) onto the water pump as I was installing it. The remaining hoses I installed after I had the water pump bolted into place.
Good luck! Might be worth replacing all of the hoses and fan clutch while you’re in there. I think I paid about $60 for a new Aisin fan clutch on Rock Auto.

When I did mine I placed the WP on first. Used a Toyota gasket and not the junk they ship with the WP. I put the RTV sealant used for WP's on both sides of the gasket. Just a thin coat on both sides of the gasket. Then mount the WP to the engine. After that, putting the hoses on should be a piece of cake. I used the WP as the starting point for how all the hoses were arranged. Started at the WP and moved out. While not needed, this job is made infinitely easier by removing the radiator and shroud. I took my AC compressor off as well to gain access to the heater split off of the main coolant pipe. If not doing that then, the AC compressor is prolly not required, although its helpful to be able to get things lined up. I found it difficult to get the main WP hose lined up so the bends are arranged properly so the hose is not twisted and goes on the pipes straight. Was easier with all the bits removed and out of the way. I found in my old age the extra time it takes to move things is worth the time you save not having to work around them. Limits the frustration and worth it to me. HTH.
Looks like I have an AC Delco alternator and not OEM. Not sure if i have a bracket to fit this alternator but it looks like that bracket is more in the way than the AC compressor. Appreciate the reply.
My fan clutch seems to pass the newspaper test but I cant tell if its original.Just did this on mine last week. I like to use this product from permatex when installing paper gaskets.

I'm now getting a Toyota gasket since the one that came with my WP is full of RTV. I thought Aisin made the pump for Toyota?

AFAIK they make the pump but the gaskets are different. Would stick with the Toyota.
go to TOYOTA dealer or ADVANCE auto , and buy a can or Aerosol Silicon
Spray , hit the metal / Brass tubes , quick then the insides of the hoses u plan
to install , wipe it all around GOOD with your finger , your hoses will
then WANT to glide right on the tubes just like the first Did
@ PLANT A11 , so very long ago ........
if No Silicon Spray local to Ya ........
then , this works Great too , on hoses / new dry fit ..........
( yea yea , ha , ha .....

Straight coolant works for getting the hoses on as well. Dip the ends in a bucket of the coolant you drained from the radiator, and they go right on.
I did what Robert Franke did with the hoses, dip em in coolant. I would not use any petroleum based jelly on the hoses, it will degrade them. RTV works, I used Aviation gasket cement. Its what i have used. You only need small amount. I let my stuff sit overnight after install to set.
I too moved AC compressor out of the way, it s easier to place the lower water outlet hose on..thats the booger of any of the hoses. Another hint. Align your clamps so you may adjust after its all back together.
Good luck and send pics of your progress.

Important point. Try and see where the clamps will end up before its all back together. For example the clamp that goes on the oil cooler hose off the WP is really close to the A/C belt after its put back on. You may not remember that as the belt will be missing when putting this particular hose on. But it will become painfully clear once you go to put the A/C belt on. If using the Toyota clamp, it may hit the belt once its on if not arranged correctly. Worm gear type clamps should be easier to work with here. Just double check that the clamp heads won't hit anything and are still accessible for adjustment after everything is put back.
Yeah, that one belt is close. The progress made today was just prepping everything until the new wp gasket comes in. I removed the bracket holding the alternator which gave me enough room to work with that lower oil cooler hose you mentioned as well as the lower pipe next to it (that attaches to the biggest hose to the wp). I didnt have to take the condenser out. Feeling much better now that I have proper access.
The other potential snag is the wp 4 bolts that are used to attach the fan are a tad longer than the original. This doesn't allow me enough space to slide the nut between the fan clutch and the back plate. I'm just going to use the old bolts since I know there's clearance for the nuts.

Assuming you mean the studs to mount the fan clutch to the WP. Or do you mean the studs that actually attach the fan to the clutch? I replaced the fan, clutch, and WP all at once last time I did it. Mounted the fan to the clutch outside the truck, put the new studs in the WP, and then mounted the fan/clutch assembly to the WP. The nuts to mount this assembly were a whip to get on and started. I ended up putting some masking tape on the end of a wrench, and put the nut in there. This held the nut in place enough for me to get it lowered down and started with my other hand. This was from the top looking down. Maybe there is another way but with the fan shroud in place I couldn't see how. HTH.
