Fixing the Ecoboost - Overheating - EP7: Towing Test with Full Race Cooling Upgrades 

Awesome job with before and after. I know it took a bunch of time to put this all together for the video. It’s appreciated!

Great series to document all the mods. I really enjoyed them.

Thanks for putting in time and effort for this video, much appreciated.

Great video, I'm sitting here getting ready to do the same mods to my truck minus the Manifolds. This test is exactly what I was looking for. I live in Utah too and need the help when pulling this trailer in the summer. I'm also doing a 170 thermostat, AFE larger Transmission pan, and an air/oil seperator. Might as well dump a bunch of money into this pig at 150k miles.

Great series. Nice job!

Appreciate the series of videos and the tests performed. I just received the full-race radiator today; will hopefully get it installed this weekend. Like many, I get frustrated seeing high temps when pulling our camper. Hoping to see good results! Keep up the good work!

Best mod i did was trading it in for the V8. Problem fixed!

Great job with posting some data and working at keeping it pretty consistent around the testing parameters. A lot Eco's see high Coolant temps at altitude, the cooling system really seems to be under engineered for the extremes. I have a 2014 with a ton of work done to it and even did a delete of the factory oil cooler for a air-to-oil remote mounted cooler as I didn't like the "diverter" used in the lower rad hose to send water to the oil cooler.

Sweet results! Especially on 35s!

It's good to experiment, your running 35s on 373 gears your towing is dramatically less , explaining thar to diesel owners with 38s they hated mpg

Hey brother!! Love you. Didn't know you started a channel. I'm subscribed bro

Second run air temps were cooler and 1st run was either really hot outside or heat soaked since ait started at 120. Not conclusive enough to justify money spent. I know you can't control the weather . I do appreciate the data. Thank you for doing this! But can't wait to get a diesel truck man this blows .

Founds it, looks promising, only thing I dont have is the oil cooler. Are you running a tune of any sort?

Lots of great info. I have the exact same issues on my 13 ecoboost. I was towing 8k when it was 100 out and I had to drop it into 2nd along with turning the ac off to keep it from overheating. Not fun lol.

Well done on the video.. Im working through overheating on my 2013 Ecoboost while towing in the Rocky MTNS..

My 2011 3.5 only overheats when it's 85 or higher outside. I tried to pull it to Bryce canyon last week from SLC and it was stressful to say the least. I'd like to see a test like this in the heat (90 plus) going up a big grade like Parleys canyon.

Same question as below…Did you run it with just a new thermostat or everything together? I just replaced my thermostat to a 160 degree because I was overheating with my camp trailer. I also just had both exhaust manifolds done and my left turbo replaced. I’m headed out of town this weekend and super nervous about overheating. Do you think a full coolant flush will help at all?

@nsqgarage How has all the upgrades from fullrace been doing so far? I'm looking into doing all of the upgrades to help with heat and be able to tow with better cooking than factory. And have you seen the new formline stainless manifolds that they will be releasing soon? I tried asking them to use my truck for testing lol!

I pulled my camper up to flaming gorge with my 2011 last year when it was 95 out and my water temp was riding right at the white line on the stock gauge (not sure what temp that is?). I’m putting an oil cooler on so hopefully it helps a little bit.

my 11 eco boost had the exhaust bolt snap two times. i got a '15 and blew the exhaust bolts at 75k miles, i wish they would fix it :(

Any updates on your setup now that you've towed in hotter weather? Still getting too hot or has this fixed the issue?

When's the 0-60 test coming? Haha. Interesting it didn't have to downshift running the same hill. The mods should have only been 20hp at best right (if you believe full race)? Maybe the exhaust leak was robbing you of more power than you thought.

Hey there - how has this been holding up? Hoping to use you for a point of comparison. Same cooling mods on my end albeit different brands (Mishimoto radiator & intercooler, Saudi-style trans cooler and custom oil cooler (actually not truly custom - using the OEM that Full Race uses). 160 degree thermostat as well (and tune compensated to kick fans on earlier) - though tbh I think that was a wasted mod.. once you're hot/overheating and that thermostat is open.. it's open.. so a bit pointless in solving this problem. Anyway, the other mods definitely helped but I still get hot if it's over ~80 degrees out. I'm towing very steep (6-7%), long (15 miles sustained at that grade), high heat (90-105). Towing a 30' travel trailer for reference - about 7000lb loaded. But it even does it when towing my 4500lb boat. Doesn't seem to do any better/worse between the trailer and boat as far as heat goes. I have NOT swapped the radiator hose - that's my next step. Have you had a chance to tow in hotter climates (same 6-7% grade?) - if so how is it doing? I'm trying to determine if this hose swap makes a significant difference. I'll admit the results you got here were more drastic than what I saw, so I'm HOPING that hose might be the smoking gun. My next step after the hose might then be followed by moving the oil cooler up higher and fitting its own fan to it.

The only test I want to see is that hill in Hatcher Pass

Its been a Year later, how are you liking it? What's you hottest summer temperatures. We get to 116 degrees

Was that the stock thermostat both runs? Or did you put a colder one in with the new radiator

Like engineeringexplained but with trucks
