Engine stalling, something I noticed...

[Jeepwalker]

I guess this should be kind of obvious (but I wasn't thinking about it before), ...after changing the t-stat the engine doesn't seem to 'chug' at stop signs and threaten to stall-out like it was before. It's only been a couple days so the jury's still out. Previous temp was ~162, now it's running around 200F. The new T-stat might be flaky-high ..but that's another matter.

Anyone else notice this?

I5 or v8? Ls engines run funny if thermostat is stuck wide open and can't reach operating temps. Not sure on the 5cyl but I'd say same applies.

The newer t-stats are 10 degrees hotter for the newer emissions standards.

Your old tstat was probably stuck open, keeping engine temps very low and keeping the truck in open loop. You may probably had also poor mileage and a rich gas smell at idle!
Those newer t-stats were rolled onto 2008+ models.

Just for reference I bought a new Dodge Ram 2500 to pull a travel trailer. I've had to get used to the fact that the engine is designed to run in the 210-215 degree range. Seems too hot considering what we were used to back in the "old" days. This darn truck gets as good of mileage as my 3T. That is surprising and is an added bonus.
