Roger M.
Worked perfectly. Easy install. Lowered my temps.
Hunter F.
Amazing people at SPE. fast shipping and amazing quality as always. The item does exactly what they say, in this Georgia heat towing a 40ā gooseneck loaded down I was seeing temps @ 235 -240. After installing this item it dropped my temps to 200 -205 going 85mph. You canāt beat these guys!!!
Yee yee.
Cody C.
Great product, without towing anything truck stays constant 175 or so, have yet to tow a heavy load but was seeing temperatures around 200 just driving already looks like it will be a great addition to the truck
Clint V.
Tyranny, oil and coolant temps all dropped. Great product. Another home run
Dave r.
Easy install. Did a complete coolant change to new style from ford. Truck runs cooler- 188 degrees instead of 195 degrees. Opens at 175 and seems to control at lower range. Quality item construction for a decent price
Petr B.
I have installed the thermostat and the coolant temperature came down from 205 degrees fahrenheit to 177 degrees fahrenheit. Works great will purchase more for other trucks.
Tony G.
Drained about 3 gal of antifreeze from primary system. Install went perfect because of the perfect OEM fit of the thermostat. Havenāt towed with it yet, but with south Texas heat, my oil temp is constantly 185. Weāll worth it just for that!!!
Eugene B.
Haven't towed with the new thermostat yet so we will know more on colorado trip in September but so far so good. Easy install for sure
Joshua H.
If you tow a lot this is a must. Towed my camper from Fort Smith AR up to MN in 100 degree plus temps and never seen an engine temp above 215. Average temp was around 190 running 70-75. Love these thermostats wish i would have ordered them sooner.
Anthus B.
Great product!! Lowered my ECT by 20Ā° and trans temp by 15Ā°
Dustin M.
Easy install, truck runs 16-18 degrees cooler in all fluids around town canāt wait to see the difference in temperatures while towing
Gilberto P.
Awesome product & super easy to install.
Frederick W.
Simpl to put in. Itās a thermostat,
Iām currently staying in the San Juanās of Colorado driving/towing at high altitude.
Temp drop is as advertised, trans 180
Oil 185
Trans will go to 210 on long steep climb.
Engine seems to be running abit smoother.
Brandon D.
Super easy install, engine and trans run about 15-20 degrees cooler!
Tony C.
Installed the thermostat last weekend while also installing the upper radiator hose kit. So far the truck hovers around 185-190 max for the oil temp. Very happy with my purchase.
Dakota W.
Installed and dropped Coolant temp and transmission temps around 10 degrees good modification to get transmission temp down some
Doug B.
Didnāt take pics of the temps but my trans would get up to 242!!! I was referred to this company for this thermostat and immediately noticed a huge difference. So far Iāve only seen it get up to 201 and back down to 190. Beyond impressed and highly recommend.
Kotie S.
Installed the thermostat becuase my oil temp was getting a little warm while towing. Dropped all my temps approximately 15-20* depending on ambient temp. First toe test in a few weeks and expecting to see some good results.
Justin S.
Loved the process of everything, was my first purchase from SPE and definitely will be doing it again! More things I want for my truck and the best quality is key and SPE is good quality! Super easy install, instructions where 100% and as promised, lower temps !! Thanks SPE
Chris
Was great working with the SPE Team. Their products are amazing and the quality is top notch. In addition the packaging was very good to ensure everything came as it was designed.
Quinton T.
Faster shipping then expected, awesome detailed instructions, noticeable temp drop as well! Will definitely suggest this part to others and this company to deal with.
Chris S.
Great price, excellent quality, keeps coolant and oil temps in check .
Steven B.
Super quick service. Great product.
Anthony R.
Works as described pretty easy install Temps are much lower I'm glad I purchased this part
Thomas S.
A wise choice to replace this thermostat while doing the CCV reroute.. Super easy install and look forward to reaping the benefits..
Theresa E J.
Straight forward install, easy fit
Alejandro G.
Fast shipping, i was getting email that my item is on its way. I already had the item installed when i was getting those notifications. Product works havenāt seen the transmission go over 195 before Iāve had 209.
Amazed with the product and service.
Greg G.
Great product! Lowered running temps by 20 degrees like advertised
Mikioi E.
Looks and fits just like the OEM thermostat. Haven't had a chance to work the truck but the quality of the part itself is top shelf.
Paul H.
20 degrees cooler while towing! The install was great. Just drain your coolant down & the rest is easy from there.
Mike P.
Awesome products great instructional videos.
Jacob A.
Best investment Iāve made for my truck, easy install and I see much cooler temps now.
torey s.
Great product, great instructions and easy to install!!
Adam S.
Lower temps, who wouldnāt want that.
mark g.
I just finished installing and what a improvement. Now for the record itās 80 outsideā¦ the real test will bee when iām pulling the trailer.
Corey C.
Old thermostat out, and new one in, running temps have not been above 183 since I installed. So far all the SPE upgrades have been really high quality.
Fred B.
High flow....low temp. Does exactly what it says it does. We pull in 100+ degree weather and the highest I see the oil and Transmission now is about 207 and 203 respectively in that heat pulling 8,000 lbs. If I did not have this then those temps would be a lot higher for sure. Great product!
Perry M.
I pull a 12000 lb 5th wheel as well as construction equipment and needed a cooler running diesel motor for better performance.
Scott G.
I have a 2017 F350 with 410 gears it would normally run 200 2 to 210 with every day general driving now it stays 180 to 185. This should really help when towing my 44 foot fifth wheel.
Jonathan D.
Installed my SPE Low temp High flow thermostat and I love it!
Pulled a load of hay and my 2011 F-350 ran way cooler then before, it dropped my Transmission and oil temperatures about 10 degrees. I definitely recommend buying this SPE Thermostat. GREAT PRODUCT!
John S.
Thermostat works excellent. Very happy with it. The only problem was it was on back order and took me four months to get it, but it was worth the wait.
Troy F.
Fit like a champ.
Great product.
Kevin M.
A must have for these torque monster 6.7ās!!!
Tranny much happier at lower temp ranges, especially in the very humid coastal region that I work and travel.
Jerad E.
Great replacement
Andrew S.
Well built. Works as advertised.
Cody B.
Love the part fast shipping
Ryan R.
Easy install and does exactly what it says it does
Brandon W.
Love how cool it keeps my trans temp way lower than before
Gary C.
New to the diesel world with a 2015 F350 DRW. Installed the Thermostat without comparing before and after as I wanted to make the upgrades before hauling. Ran the truck to Tucson and Prescott from California to pick up a new horse trailer. No problems whatsoever. Then ran the truck under load running to Northern CA for Turkey Day. Again, no issues whatsoever. The truck ran exceptionally cool while running up the Grapevine towing 15k+ lbs. on the bumper and it ran perfectly.
Not sure if the product did what it was supposed to do however, the temperature on motor and trans worked perfectly. Definitely support the product as it is an easy install, even for a Diesel virgin!
Tytus B.
Dropped the temps dramatically. Trans and oil temp barely ever see over 185Ā° now. Very impressed
Edye R.
Really easy to install. Saw the difference and the first test drive.
Adam A.
After oil temps shot up to 235+ when towing I had to get this! Oil, coolant, and trans temps are back where they should be now that it's installed. I bought two at the same time and gave one as a gift to a friend :)
Leopoldo Q.
Great product !! Wish I had done the thermostats sooner.
Ken J.
2017 Ford F350 Lariat -6.7 Powerstroke
Bought the SPE thermostat designed for the Powerstroke as I was having issues pulling my 40' triple axle 5th wheel during the summer when outside temps would get above 95 degrees.
I was going to flush all of the fluid, replace a couple hoses and make sure system was in good shape - when I ran across the SPE Thermostat. After reading the reviews, it seemed like a "no brainer", so I bought it.
I have installed the new SPE Thermostat and have nothing but good things to say.
Super fast shipping - got the part in like 2 days.
Super easy install - only had to pull 3 bolts on top of the motor.
Engine oil temps before installing were running 199-201 (not pulling trailer, highway driving at about 75mph, and with OAT of about 75 degrees).
Engine oil temps after install dropped to 181-183 right away under same conditions.
Can't wait to see the change in the summer pulling the trailer, but I am sure it will make a huge difference.
Well worth every penny!!
Juan H.
Great product, no problems with the install. Truck seems to run a little cooler.
Robert H.
Great product and would recommend this to everyone with a 6.7.
john s.
works as advertised noticed about 10 to 12 degree drop in temps oil, transmission, and coolant temp gauge.
Chuck M.
Absolutely thrilled with the immediate drop in temps on my 17 F350. The running temps average about 14-17 degrees cooler than I experienced with the factory thermostat. It will be a big help in keeping the oil temp a little cooler when towing a trailer over the mountains.
Matt H.
Trans engine and oil all run about 15Degrees cooler than oem
kyle w.
The high flow low temperature thermostat fit great on my 2017 F350! On average the trans temperature and oil temp were 15 degrees cooler. Thanks SPE for another solid product!
Zane C.
Dropped my oil temps by 10 degs. This is exactly what my truck needed.
Thomas R.
Great experience all the way around
DAN H.
20 degree temp drop for oil and coolant temps. Worth every penny
Roy H.
Installing this part was straightforward. Fitment was great. Haven't had to tow with it yet to see temps.
Troy K.
Excellent product! Works as described. Temp levels in trans 10-12 degrees cooler on average. Oil temp 12-15 degrees cooler on average. Iām satisfied. Thanks SPE
Tyler T.
Definitely needed a new one! Truck runs at 165-170 and oil temp is at 176 at idle and 187 at 85mph cruising. Definitely recommend
Karl B.
Working like advertised, keeping the engine cooler, and the engine oil cooler. Will help when towing in higher temperatures up ling steep grades and mountains.
Jared F.
My trans temp went down 28* and truck runs way cooler. So stoked.. great product.
Cody C.
Great product. Installed easily and is a huge help towing on the 6.7 PSD
Francis T.
Tried and true! Towing a 14k lbs boat on a weekly basis and this just gave me an assurance to not overheat for more boat hauling days to come! Thank you SPE!
Steve W.
Receive item quickly, installed in about 1hr. prior to installation took temp and transmission readouts. After hitting the highway for about an hour, looked at temps for both. Water temp was 7 degrees below and transmission temp was 6 degree's below what I normally saw. Will be traveling with 40ft 5th wheel first week in October. That will be the real test since there are a lot of hills on our route to Oklahoma City, will let you know the outcome. Installation was done to my wife's 2017 Ford F350 dually.
John W.
Unprecedented communication after the sale with shipping information email and text. Easy install and engine and trans temps saw a drastic decrease towing our 45ā LQ horse trailer at interstate speeds
matt r.
Worked as advertised.
matthew r.
Worked as advertised.
jeff d.
Dropped coolant levels as described. Was hoping it would drop Transmission temps but it did not.
Jerrid G.
I put this thermostat on my 2013 6.7 and loved it so naturally it was my first mod to my new truck and let me say it still doesnāt disappoint. Ford says these engines normal operating temp is 220-240 thatās just crazy to me. I just took a 900 mile trip pulling a horse trailer with 2 horses in it in mid august in Texas where temps get 105 easy outside and oil never got over 205 trans 203 was the high and coolant 187 such a work of art heat is a killer and this bad boy keeps it nice and cool
Jonathan B.
Great packaging, quick shipping. Obviously a thermastat isn't a difficult install. The actual difference is immediate. It does exactly what they list. Works flawlessly and 100% love the purchase. Everyone needs this, if you are reading this... just buy it already!
Brody W.
Product works great. Engine oil remains 13-15 degrees cooler at 188, trans 20-25 degrees cooler at 175, and coolant temp remains around 177-180 no matter how heavy my foot is into the pedal. Excellent product!!
Daniel M.
New low temp thermostat works great! Did exactly what I wanted, lowered coolant and oil temps over 20-25 degrees during normal driving and 10-15 when towing. Fast shipping too.
Shawn F.
Headed to Colorado!
Corey G.
I wish all companies were this responsive and produced great products like these folks.
Look forward to doing business again.
Jordan H.
This product shipped very fast, the fitment was flawless and the install is easy, my temperatures have dropped on average 15 to 20Ā° unloaded and 10 to 15Ā° loaded. I tow heavy daily up to 7000 miles a month This products has been a great purchase at a great price.
Anthony A.
The Ford 6.7 SPE thermostat is the real deal. I live in South Texas where its hot then a well you know.
This thermostat drops engine temp!
oil temp from 204f to 180f
trans temp from 180f to 160f
Best money you will spend on a 6.7 Ford
Scott S.
Purchase one for my ā11 F-350. 20 minute install. Waited a while to post until I tested it. Engine is constantly 20 degrees cooler. Hauling Arctic Fox 990, and towing 14ā dump trailer w/ Polaris General 4seat. Best $67 Iāve spent on my truck. Bought another one for my father-in-lawās 2012 F-350. Same performance. Thanks SPE
John H.
Love your products. Awesome
