SPE 6.7L Powerstroke Low Temp, High Flow Thermostat

Another awesome SPE product. Installed when I did the whole engine bay with SPE goodies and had the coolant drained down. Easy install. Quality Product. Another no brainer.

The thermostat was an easy install. Be patient and drain the coolant and there won’t be any clean up. I’m going to use one of my upfitter switches and a 12 volt relay to ground the clutch fan when towing in hot temps or uphill grades. Hopefully this combo will reduce engine and trans temps.

Took my engine oil temp from routinely 195-210 pulling hills with a 75hp tune and ambient air temp of 78 to 178-192. Like your other products I’ve installed it was high quality. Thanks
