Well, I've only got 70K on my 2002, so I haven't had to cross that bridge yet. However, I plan to get 'er at right at the recommended 90K -- losing a belt on an interference engine is seriously bad mojo.
I recommend changing the timing belt at the book interval of 90K. I had mine done in my Tundra at 93K. I also had the water pump, idler pully, serp belt, thermostat, coolant.....all done. The timing belt is about $35. Nothing except used fasteners went back on and I spent about $250 on parts and about the same on labor.
It would suck to have a water pump with 90K on it reinstalled just to have the bearings fail 5K later. Cheap money for peace of mind.
Toyota recommends replacing the timing belt every 90k on vehicles modle year 98 and newer, and 60k 97 and older. However the part # for the timing belt are the same for 96 through 2002 4 runners. I think they relized you can go farher than 60k. They are also able to advertise longer maint intervals this way.
There is a lot involved on the V-8 t-belt (a lot of parts to take off). Definatly replace the water pump, t-stat, and serp belt at the same time.
I did mine myself at 105K miles. Just a lot of parts to remove, it's time consuming.
I replace my timming belt, idler pulleys, belt tensioner, water pump, thermostat, serpentine belt. I call the dealership around and it would cost me $1000 - $1200.
90 to about 100 tho. miles is the best time if it goes it will cost a whole lot more to fix all the other damage. And its best to do the water pump also with a new belt it is alot tighter then the old one so it puts more pressure on the pump bearings so most likely it will leak and you will have to tear it all down again
Just did the timing belt, tensioner, serpentine, thermostat and water pump at 80k miles. Was advised by a friend to go ahead and replace the pump since I already had access to the part. Would hate having to remove the same stuff just to save a few dollars in parts.
Took me about five hours, but went through the maintenance manual I had thoroughly to make sure I wouldn't miss anything. Didn't even have to set at TDC, just made sure the camshafts did not rotate as I was replacing the water pump and belt. If you are mechanically inclined, I'd rate it a 6 out of 10 for difficulty.
BTW, a friend who worked for a Toyota dealership told me that there is enough clearance between the valves and pistons, that the belt could snap and you could still crank it and not damage the pistons, although I don't recommend trying to find out if it's true..
My experience has been the Toyota water pumps last 150-250K if Toyota brand coolant and distilled water is used. The timing belt idler pulleys are good for 150-250K too (at least for highway type drivers).
So I figure the best overall strategy is to do the timing belt alone at 90K and then
the timing belt again at around 160K and then do the water pump and idler pulley at that time (plus any oil seals that may be starting to leak)
The engines the call for a 90K timing belt replacement interval have a heavier duty type timing belt compared to the engines that have a 60K interval.
I just had mine done by the dealer since I just bought my truck with 98,000 miles on it and the belt wasn't done yet. They changed the water pump for me too. I called the service dept and they wanted $475 to just do the t-belt.
