Thermostat Replacement - Use OEM?

[dnicholas47]

My thermostat on a 2019 is shot. Stealership wanted to charge $1300 to replace it, so I said thanks but no thanks. Question is am I better off using the redesigned Ford thermostat or an aftermarket one by Mishimoto that opens at 160 degrees? https://www.summitracing.com/parts/mio-mmts-mus8-11

OEM for sure.

Use the OEM Ford one. That quote is ridiculous. Try calling around.

Stealership

HAHAHAHA... I like this, so funny but unfortunately, so true in some cases....

Like the one dealer who quoted me $3K to replace the power running boards on my 011 EL, cause

A) They don't sell the parts separately, and
B) They only sell & install the boards ONLY IN COMPLETE PAIRS....

Fortunately the boards themselves are still in great condition (i resurfaced the step area myself) and I only needed the motor and brackets for the left side, which I found online for $135

Wasn’t there a thermostat redesign for 2018-2019 with TSB? Maybe even a recall? Something about them and manufacturer changes. O just can’t recall what (damn old age)

The Stant SuperStats were my go to, but they're no longer in production afaik. Whatever you go with, I would stick with factory temps.

There was a redesign but not sure a TSB was sent out.

I went with an SPD 170°

Ford quietly redesigned the thermostat in 2022...replace it

If you are having cooling issues you should know Ford quietly redesigned the thermostat in 2022. Replace it now if you have the old one. The problem was the thermostat sticking closed. The other thing to know is thermostats do not last forever and should be replaced every 50,000 miles or any...

Some good related discussion in this thread.

Go OEM only and get a requote. It's probably 3hr labor and the parts aren't too costly. Shop around, or ask what the $1300 consists of. Is there additional service? Coolant flush, hose replacement, is it the whole t-stat housing too? My dealer did the whole housing on mine too, apparently it can be ordered as a kit.

Thanks everyone. They tried to tell me that gaskets that have to be removed are one time use and have to be ordered, and then went on about how much labor is involved, I guess assuming I hadn’t done any homework before I took it in. I will stick with the resigned OEM thermostat and find another dealer when I need something in the future.
