Within the last 1000 miles I have done the center support bearing, rear main seal, new plugs, pre cat 02's, secondary air pump, MAFs, and fuel filter. Cam position sensors, thermostat and water pump should do the trick for now, I hope.T-stat and preventative CPS's? Might as well do the crank sensor, MAF's, spark plugs, plasma coils, all hoses and water pump, and probably timing chain guides as well. After all, you'll have the plenum off...
Thanks, do you happen to have part numbers for those?You can do the Tstat without pulling the plenum housing.
You need at least 6 of the large O-rings and you should be fine with the 2 smaller O-rings. You will likely break at least 1 of the larger O-rings unless you are REALLY careful.
Recommend putting the small coolant tubes in the block then drop stat housing down and flat, then insert the coolant tubes into the stat housing, if you do this on an angle, you WILL break at least 1 O-ring.
As for other things to do when replacing the stat, oil return lines, oil seperator cleaning or replacement. Possibly the lower oil return hose if it can be replaced without the water pump removed??
