    I thought about buying one to look at. They arn't THAT expensive. I believe the biggest hurdle might be that you cannot fit a smaller pulley on it because of the crap behind the pulley.

    I just came across the higher temp SPD stat over at 5 Star tuning: https://5startuning.com/product/spd-...ostat-ts18035/

    Doesn't drop at low as the 170* ones that I keep seeing, so if there's an increase in performance it might be a good "in-between" stat for those in colder climates. It sure is expensive for what it is. I checked the SPD website and it's not even listed. I wonder if this is new or a discontinued part.

    Not yet. Wondering if I should spring for the SPD 180* and do a three-way comparison. We got pummeled with the pineapple express making it's way across the west coast so I'm sure shipping will be delayed a few days due to weather.

    How about the 5* RAT 170° T? That's what I have not a SPD. :blush:

    Truck takes forever to warm up in my area with stock stat as it is (Currently about 5 degrees outside). If I install the 170 the truck would be making ice cubes. Looking for something with more flow or better control without the low temp aspect.

    The only thing a lower t-stat is going to do is give you an extra few seconds before you begin to overheat. They work great for quick sprints but offer little benefit for prolonged high loads (towing).

    The stock t-stat opens around 180-190'ish? But everybody is complaining of temps above 220. Wide open is wide open.

    I ran a 170 for a full year and wasn't impressed. When coasting down hill in cooler weather coolant temps would drop down to 160f

    I think we should all send a email to @Mishimoto and ask them to do something about it? Or hopefully @NMB2 would probably do a better job

    Mine does this too with the stock t-stat.

    What might help is if the replacement t-stat is less restrictive and can get coolant out of the radiator faster. The faster the flow through the radiator, the hotter the average temperature, the more heat gets dumped. You let the coolant sit to long and it cools and doesn't give off as many BTU's.
