    They do. You just reuse the gasket from your stock thermostat. It won’t fit so tight making installation a lot easier.

    This. The gasket that came with my SPD thermostat was whack, I reused the OEM oring and all good.

    With all due respect to you guys making comparisons to big-bore diesel tuning, the OP was asking about installing a lower temp thermostat. No one was providing misinformation when advising him to save his money. He did not say he was building a desert race truck. If he’s planning on making lots more horsepower he’ll need much more than a thermostat and a tune. A complete analysis and upgrade of the cooling system would be necessary, including flow rates, radiator surface area and thermodynamics. These motors are very different from a Cummins or Powerstroke, including expensive catalytic converters that don’t like high heat or overfueling.

    baugustine, you mentioned that sitting on I-10 in the middle of summer would be a different use case. For those of us that live in Houston and deal with this use case regularly, does your opinion on thermostats change? Are there other upgrades/changes/solutions you would advise?

    My motor was running up to 220. Being old school diesel that looked too high. So I put in a 170. Runs 190 to 200. Fans come on at 190 so it doesn't.t make sense to open thermostat and start fans
