I have to do water pump and head gasket in a couple of months, and wonder what I should get done while things are apart. 1. Timing belt - might as well, though it still has about 30k 'till next change. 2. Since the head will be off, I thought it might be worth a refurb. Reseat valves and general clean up. 3. T-stat and cooling hoses. Rad is fairly new (a few years and only about 20k miles.) Anything else (besides normal maintenance stuff)?
