I just noticed a tablespoon size puddle of coolant under the truck. 2003 EXT with 91k miles. It has the original water pump as best I can tell and that seems to be where the coolant is coming from. I am going to replace the thermostat while I am in there and also the smaller belt for the A/C. The main belt looks new (I have only had the truck for a month) so I am going to leave it be. While I am under the hood, I will also do plugs and wires. I sometimes get a rough patch or stumble while idling.
Anything else that I should replace or evaluate while I am at it. If there are parts that are known failures, I would rather replace them on my schedule versus having them fail while on the road. I did a search and saw where some replace the idler pulley and tensioner, but is that needed? I plan on owning the truck for another 100,000 miles and want it to be reliable.
