    Getting ready for winter and got blessed with decent weather for Thanksgiving weekend, so here goes...

    Water pump has been whining for a bit, which of course prompted a domino effect. I've had parts in the garage for a while now:

    AC Delco OE water pump w/ stat and housing
    Idler and tensioner pulleys
    Serp belt
    A/C tensioner & belt

    Then some extras to make the whole project worth it... lol

    Heater tee fittings (NOT PLASTIC!)

    Dexcool, distilled water
    Constant tension (OE style) hose clamps and some silicone hose pieces purchased through McMaster Carr.

    Since I was replacing the tees at the firewall, I got the Dorman piece with the metal tee by the pump. Then I found this and couldn't resist....

    Friday night I drained the system via the lower radiator hose. Then I filled it with the garden hose, ran it for 10-15 minutes, and drained again. I repeated this 5-6 times while I sipped a few brews until it was running clear. Then I pulled the pump and let everything drip overnight.

    Saturday, I did the job. Everything went smoothly and according to plan. I pretty much just copied @iamdub on the tees (cutting the rear lines to fit). I used the peices of silicone hose and spring clamps from McMaster. Yes, I put the wiring back where it belongs when I was done...

    Then I replaced the A/C belt and tensioner. I used the green Gates belt. Installed the AC Delco OE pump, tensioner, idler, and serpentine. Refilled with new Dex and distilled H2O.

    Love the red silicone hoses from Glenn's. The truck is definitely faster now and has exactly ZERO plastic tee fittings in the cooling system! Topped it off with the awesome NBS sticker they sent!

    Wait....who are you? What did you do with Nate? Just kidding. Looks great. I want that hose kit but I think I’ll do mine in the black to match all my black braided ones for the blower and catch can. Does it feel faster? :)

    Mine are dipped also. I have my color black paint and clear coat. After peeling the dip, how do you recommend prepping them for paint and clear coat? Light sand? Which grit? I think they are painted a light pewter now..

    I scuff my stuff with scotchbrite and denatured alcohol, then wash with Dawn dish soap and after they’re dry, clean again with the alcohol and dry wipe again after it evaporates.

    Red looks damn good.

    Questions for ya - what is the part # for those Dorman T's ? And did iamdub do a write-up for the changeover ?

    This sounds like something I should do before they break.

    Thanks.

    The tee fittings are from here:

    https://jagsthatrun.com/products/traditional-hose-tee

    @iamdub's more detailed post is here:

    https://www.tahoeyukonforum.com/threads/growing-up-doesnt-have-to-suck.93510/page-68#post-1451010


    The Dorman piece i was referring to is
    # 626-538

    I did not end up using it, as the red silicone kit has the molded tee by the pump instead of a fitting. Win- win.
