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!
