im a baby I guess, I’ve only got 22k miles on my 2014, lol…we need a thread for the lowest mileage on trucks that are at least 3 yrs old , so no one shout outs his newbie, lol.

.really though they said the ecoboost is the most reliable of all the F150 engines, based on complaints and maintenance..
also didn’t ford run t on a engine stand at wide open throttle for 24hr or something and then 12000 hrs on a dyno at varying engine speeds for 500k miles then 500k driving on the road , it totaled a million miles without a failure ,that was the 2011model in 2008 before they fix it..
 
I saw some people are just cutting the crimp off which reveals the barbed end underneath and just running 1/2" transmission hose with clamps from there up to the coolers.
Yeah we used to do that all the time on everything with wheels when customers didn’t want to buy new hoses from the dealer..
