I'm at 177k on my '99 Quest and I'm on the original belt. These are non-interference engines so there shouldn't be any damage to the engine if it breaks.
There could be some body damage if it breaks in heavy traffic, strands you, and you get hit, but I don't have a commute and decided to defer that maintenance.
Never looked into it, but just assumed all you had to swap out was the crankshaft.

Seems that the heater cores in these vehicles (99-00 Nissan Quest/Mercury Villager) have a control valve located right on the coil. If this fails, you have to remove the whole ventilation plenum which includes the A/C coil. That's right, the A/C has to be discharged to remove the plenum in order to get to the heater core to replace this valve. Not sure of the cost of these valves but for a shop, this would be an expensive repair.
Heater Core Valve Replacement
However, I have also seen this inline valve:
on the back fire wall that runs into the heater core.
When I felt the hoses, one was hot and the other was luke warm, indicating a lack of flow. It's one or the other and I have not figured out which as of yet.

#77 of 77 Quest defroster not working, large control buttons sticking
Oct 27, 2013 (3:48 am)
Last year the defroster button (one of the three large buttons/controllers on the dash) became stuck and now the defroster does not work. Also, i have noticed the button used to toggle AC on/off has started sticking as well.
I have determined if the outside rim on the gauge is turned to the far left, it pops off. Unfortunately this just seems to allow me to see the button I am frustrated with better. There is no obvious way to take the next step and remove the interior portion of the button.
While the old mechanic side of my brain which grew up working on my Dad's 68 El Camino says, "spray 'er down with WD 40!", my new super subcompact foreign engine brain is saying no.
Any suggestions and/or brainstorming appreciated.
