I drained my transmission today, and removed the pan and replaced the filter. Refilled with 5 qts of dex VI. I felt ambitious so I did the hayden fan clutch and ac delco water pump i've been sitting on. Fan is actually much louder, but i've heard they quiet down over time. I hope so anyway. OEM water pump lasted 160k, bearing started to squeal. Internals looked fine. I broke a water pump bolt while re-assembling. I checked the spec after I broke it, it was rated in INCH lbs (89 lb/in). Luckily autozone had a replacement. Glad I only broke one of them. I did use a little RTV on both sides of the gasket. This should be this trucks last water pump.
