Motor coolant over temperature. (Truck in dealer service department, Coolant Pump needs to be replaced)

[jaykoolzboy]

Just got delivered last week, now showing this. Any inputs?

Updates since 09-17-2022

09-17 Receive the warning message Coolant Temperature High. Posted on F150 Lightning forum, Ford social media team contacted me right away.

09-19 Sent Lariat ER to Chino Hills Ford service department, receiving my ticket number immediately with a Ford Service specialist.

09-20 Ford sent Lightning Technician on-site next day (service manager insist that it never happened before), Tech determined coolant pump needs to be replaced (ordered all the parts while on-site with next day delivery)

09-21 Called the service manager, they are expecting parts to be arrived by 09-22-2022, it will be replaced upon the parts delivery.

Wow , understand I am sort in a unfortunate situation (1 week after deliver), but the whole experience made be think that Ford is really on the path to metamorphosis, Kudos to Jim Farley and his team.

I am getting more F stocks (experienced very similar situation with Tesla previously, look where they are at now)

Check fluid levels

Either a software issue, a temp sensor issue or there's a genuine issue with the supplemental cooling of one or both motors. Is the coolant level on these trucks user-serviceable? Either way, I'd contact Ford immediately and I wouldn't drive it as it could leave you stranded.

I hope you get a quick resolution….let us know how it works out…….

Will do , still can't believe this happened within 1 week of delivery. But hey, I used to own an range rover

Do you see this even when the vehicle has been at rest for a while and is cool? If yes, it has to be either software or sensor.

Regardless, wish you good luck with speedy resolution. Please let us know what you find out and if it was something we could address if we see the same (like a loose connector to a sensor). Rivian has had issues like this with suspension sensors.

With or without Max Tow?

With max tow

Isn't there a thread here about many lightnings being delivered with coolant at MIN mark?

Low (or no) coolant is my first guess.

Updates : after 2 hours of parking on street , the warning message is gone now. Prob a sensor, software or low coolant issue. I'm heading to closest dealer to have a check up on this.

Coolant is about quarter or 30 percent above the MIN line (compare to the MAX line), anyone know this is consider low for coolant? We do also have a slope (pretty steep) in our driveway. I believe this is the most likely cause for our issues earlier.

Please check your Coolant Level during delivery


Really appreciate everyone's assistance on this forum. You guys are legit.

There should be two coolant levels. One for the battery and one for the motors.

you should be able to tow with this up the mountain. If going up a short driveway without a load gets a warning, that is still a problem.

Hi there. Will you send us a message with your VIN and dealership info? I'll see how I can assist on my end.
