Water Pump Hoses - Replacing Pump

Hi, I will soon be changing the water pump on my 95 Caprice Classic. I've not done this before but I've been reading up on it here and elsewhere and watching videos. One part that concerns me is that I need to replace the lower hose the connects to the water pump and goes back to that bracket or clamp just under the tee (circled in photo). The clamp is obscuring my view of how the hose connects. Can someone fill me in? Anything I need to watch out for? Looks like that clamp is on there good. Also, does any one know of the Gates part no. for this hose? Any other advice is appreciated as well. Thank you. - Damian

I believe that hose has the Flow restrictor attached to it. If it were me, if one hose is bad, I would just replace them all since the others aren't too far away. Why go thru the trouble just to have another hose let go and leave you stranded.

Other things to replace/do....at a minimum I would replace both the plastic restrictor and tee. Those parts get very brittle with age and heat cycles and once you start moving the hoses around will break or be compromised and break at the worst time....ask me how I know.. I made a tee out of metal fittings to eliminate this but no option for the restrictor other than the plastic part and YES you need this in the system.

Also, a good idea to flush the entire cooling system (block, Resevoir tank, heater core), top off with a 50/50 mix of distilled and coolant and bleed the system. You may as well do a new t-stat and possibly the pressure cap on the tank.

Based on what I've read here I did order the tee, hose restrictor and thermostat. That said, I've not seen mention of where the restrictor goes just that it should be replaced. I meant to ask that.

Most of the hoses were replaced about a year ago. That lower one wasn't nor were the ones that go back to the heater core. That rear hose assembly is not cheap. I don't know that I can swing it now. I'll have to look into a flush.

Also in one video I watched the guy replaced the drive seal with a special tool he bought from a forum member. Does that seal come with the pump (it's not here yet) or is that a separate purchase?

Thanks for the reply.

I need to do this repair soon. Is this not the right forum these questions? At this point I'm mainly concerned about replacing the lower hose that's circled and placement of the restrictor.

This is the top hose coming off the pump and the location for the tee.

Here is the bracket that attaches the hoses. There is a tiny screw that you can just make out the threads for near the center of the pic. Can't remember the size, but it's small and difficult to get to.

There is the restrictor in the bottom hose between the clamps. You can see oil dipstick and ac stuff for reference. You can get the heater hose at Rockauto with the correct bends. You might have to cut to fit. Hope these help. Let me know if you need more.

Thank you very much. That helps a lot. I could not see the bracket screw before. That looks like it's going to be a pain to get off and back on. I picked up a proper heater hose. It will need to be cut.

I'm curious, will the tee just pull out. I'm concerned about the center connector. It appears to be held by the metal end of the hose.

Also, I've circled the area where I believe you're saying the restrictor is. Do I pull back on that connector, the one that's stamped "Made in Mexico"? I don't want to yank on that area it if that's the wrong thing to do.

I'm a bit confused by the lower heater hose. Does that go all the way back to that connector I circled? If so, the one on my vehicle has a metal end. I'm not seeing that available under heater hoses. Is that just the way it was initially issued and do I just now use a clamp in its place?

Tell me you aren't replacing your green 9c1 hoses with regular ones.. This isn't brain surgery. I replaced the restrictor in about 15 minutes. Just do it like the photo that has been supplied. Good luck.
