Haulin' 10K?...r/r fluids, trans etc., hd rear gear oil, got a little coolant tester? at least a little baster type with colored balls?
Also, WHERE is the fan clutch from/brand? I have had mixed results with cheapo, Hayden lifetime and factory.
What is coolant percentage mix?, cut with?, distilled water? (never use tap)
How about since you have both gauges and senders etc. use both, in different locations?
And r/r a water pump is easy when one puts bolts in a marked (from what/where) container or ziplock, pay attention to length and location, make a drawing or get a page of the shop manual and/or take a photo of before and after, or during in case you have a question.
I (used to) like snugging up parts to set gasket/sealant and torque down to spec next day for a great seal.
Take your time, a good job takes time.
