I have a 2018 Ford f-150 that wants to run hot just when I pull a trailer, a 12 foot empty trailer at that. I have taken to the dealer but they could not find anything wrong all they did is change out the Thermostat and it still same thing.

Was just wondering if anyone else has run across this issue and what you did to fix this.

Thanks in advance

I have not run across this issue in this particular vehicle, but In my experience there are a few things that could cause a vehicle to run hot like that. The first thing I would check is the radiator fans (I assume they’re electric) to make sure they’re working, if they aren’t check fuses and relays for them, the next thing I would check is to see if the radiator is clean, if your radiator is clogged with mud and dirt it’ll run hot, then I would check coolant level (I’m sure you have but it’s worth mentioning). Do you have any check engine lights or anything?

Thanks for your reply!

My truck is a 2018 xlt with 67k on it v6 twin turbo with 10 speed transmission my first ford! Been happy with on than this issue.

I have checked coolant / radiator everything is clean I really take care of my truck probably better than most. I have to make it last. I am no mechanic by far for sure just a thought I think the thermostat is a 280 what if I put like a 260 thermostat in it? What would that do good or bad? To make it open up sooner?

Thanks again

Where is the front license plate mounted? Did you mean 180* thermostat?



I hate photobucket.

Typically the lower temp thermostats are only for performance applications. You could try changing the cht sensor. If you are handy you can do it yourself, it’ll take a little while, but those things don’t usually run but about $15-20.

Had a similar problem with my '18 Raptor right after they changed the cam phasers. Going up hills it would hit over 240 degrees. Had it back to the dealer 3 times and they couldn't figure it out. They replaced spark plugs, flushed the intercooler, and checked the radiator shutter vents, still did it. Dealer took it back on a very generous trade in and I went back to a Super Duty.

The twin turbos, at least the older ones were supposed to have the license plate offset for air intake to the turbos and I guess to the inter cooler. I guess it could be different for the new ones but that’s how the older ones operate.

What's hot? How fast are you driving? Are you running a tune or any other mods? Original radiator fluid/coolant?

Temp i don't know the number, but the gauge would get way over to the right side at times if this makes since.

Driven 65-70 MPH everything is stock no tuner all original, radiator fluid/coolant yes

The water pump would be my guess. Maybe the fan motor, but if it spins and sounds like a jet engine when its hot, probably not the fan. That Gold coolant Ford uses can gunk up in the radiator. Might need a flush, but I doubt that's it only being 4 years old.

I think those use the orange, the gold is for 2011 and older I believe. Regarding water pump, if it’s belt driven, check if the belt is slipping first.

Not sure but I think the water pump is electric. Check and see if it's making oil. Some of the ecoboosts when the water pump leaks, it goes into the crankcase.

Ecoboost water pumps aren't electric. They are inside the front cover and you have to take half the engine compartment apart to change it. Engineering at its finest.
