Help! Engine coolant thermostat stuck open?

[Roguellama]

2018 Ted sport with 62000km, throws engine light, scan it says thermostat, have dealer ship scan it... thermostat, truck doesnt over heat, doesn't even fully heat up unless I'm goin 120km/h. I kinda want to repair it my self. And I can't find any vids on how too. HELP! LOL

What does the code fully say? Does it identify that the thermostat is in fact stuck open at all times? Are you still under warranty?

I didn't see it, dealership told me that's what it needs, and no the warranty is up, I'm assuming it's open because the temp gauge stays below the halfway

Gotcha.

Have you had a look at the service manual yet? Might be some good info in there for you.

Heads up it's a big file, but one that's worth having for sure.
