Replacing Belt, Thermostat, Water Pump Prophylacticly?

I have 162K on my Gen 2.

This summer I plan on a long road trip, greater than 4K miles, to some pretty remote areas of Canada, Montana, and Idaho.

I already plan on replacing my brake pads and rotors, which currently have 82K on them, before the trip.

I'm wondering if I should replace the original serpentine belt, thermostat, tensioner, and water pump on a preventive basis.

My truck has been absolutely trouble free to this point and just don't want to have an issue when I'm out in the middle of nowhere.

The rubber grommets on my control arms are badly worn, but in a previous thread I started I was told this really isn't an issue.

Is there anything else I should consider replacing on a preventative basis?...starter? alternator?

Thanks so much.

 

If really original serpentine belt I would say not a bad idea, tensioner too. If they look good maybe have on hand for your trip.

Unless the water pump is leaking or there are Temp issues i would not mess with it.

I would consider a coolant exchange if original coolant, new thermostat not terrible idea, again maybe have on hand for your trip.

Transmission Drain and fill maybe in order if not done recently.

Starter is not an easy replace and is expensive, not many replacing without failure.

Battery maybe if not real fresh.

 

Perfect, thank you.

 

120 k on my water pump, serpentine, idler, thermostat and tensioner, changed them and honestly I'm a mechanic and I the water pump looked new, albeit about a 1"x 1" spot of coolant behind the pump, probably from the weep hole which tells me failure isn't too far behind!
If I'm going to go through all of the trouble of changing the belt, I would do it all, it's a pain (so many hoses and BS in the way), but the only thing worse is doing it twice!

Now my fcuking alternator, power steering pump or timing chain will break!!

 

I guess you could use a prophylactic on each finger but aren’t gloves easier?

 

I have that fear too. Whenever I fix something I just stare at the other part that hasn't broken yet and threaten it verbally haha
