Chuck, great job, and glad to hear the maintenance/repairs went well!
I am about to do the same water pump, low temp. thermostat, and motor mount replacements on my '99. I have not noticed any motor mount related issue, but I can't imagine the rubber is still good after 16 years.
A few questions:
Where you noticing any symptoms of a deteriorating mount before you replaced yours?
Any tips for someone about to do the exact same replacements?
Did you replace the entire motor mount, or just the insert?
If you replaced the insert, how did you press it in/out?
Best,
-Rick
