Mishimoto MMTS-F2D-11L Low Temperature Thermostat, Compatible with Ford Powerstroke 6.7L, 2011-2017

Installed and haven’t seen temps over 190, even while towing going down the highway. Very impressed by the performance.

I anticipated quicker drop in temperature after being loaded. Zero noticeable change over OEM.

Very happy with this part. I was concerned with my higher coolant & oil temps pulling 20’ Cargo trailer and normal driving in the mtns I’m Colorado. Seeing much lower temperatures across the board. Easy to install and packaging was first class.

Noticed a 5 degree difference.. not worth it in my opinion

dropped my temps by about 10+

Runs at least 10 degrees cooler than the stock thermostats.

My first one lasted 11 months, Mishimoto replaced it under warranty, after I removed it and sent pictures. Now 3 months later it is defective again, when I let it idle for a few minutes the coolant temp drops to 140°.I’m going back to OEM.

Does exactly as stated

runs between 186-196f ECT2017 6.7 PSD
