Phil, for the sake of us curious ones in the peanut gallery, do tell what the old belt looks like, condition wise.
OK...timing belt, tensioner, two pulleys, serpentine belt, anti-freeze, thermostat...done...cost $855.93..FYI...work done at local garage [Mid-Town Motors, Enterprise @ 5.5 hours] with a good reputation; Roger's Toyota Lewiston kept dicking me around and blowing off requests for information, costs and when I could schedule...they lost a customer.
I retained all the parts that were removed; can't really see me replacing them on the road...as expected they all look good..no signs of rough bearings or stress and cracking on belts, pulleys, tensioner and pump..all tight and functioning...
No looking back..especially after I thought about what the Toyota "100,000" miles limit meant....wear on the components [and when need to change them out] is metered by RPMs expected over the 100K miles...with the Hawk in place I never use overdrive unless on very long downgrades and often use "3" on hills...couple that with the many miles crawling in "2nd" or even "1st" off road...my engine has seen a disproportionate number of RPMs for the 41,321 miles on odometer...I never abuse the Tundra but it is working for a living.
In the end, peace of mind...my odds against getting stuck in BFE [or Yukon] just improved...Now back to our Alaska, Yukon, NWT and BC trip planning for this coming May!
Thanks for all the input and recommendations...appreciated.
Phil
