Doesn't look too difficult just wondered what kind of time to schedule and any tips of the trade that would be good to know before changing it.

not hard, i take off the air intake tube off the tb and the maf and set aside. take out the 2 10mm bolts and the 4 push pins on the radiator shroud. take off the fan and clutch assembly. take off serp belt and the 3 15 mm bolts on the belt tensioner. take off all 4 radiator hoses. there is no real way to drain the new gen 3 coolant system so have your drain bucket ready when take off the bottom hose and the two heater hoses. take out the 6 10 mm w/p bolts and set aside. clean your surfaces up. TIP: when puuting the pump on clean your bolt threads and apply some liquid telfon sealer to the blot threads. and reverse. very easy to do. the best part there is no real messy gaskets to clean up either.
