GEN 1 Engine runs too cold?

KTag98 · Jan 24, 2020

Ever seen this before? Anytime the ambient temp is below 60 my 6.2 never really reaches full operating temperature. All stock no 170 degree thermostat, wondering if it could just be the temp sensors/gauges?

this is after 20 minutes of highway driving;https://www.flickr.com/photos/186616357@N04/49435200466/in/dateposted-public/

and after 45;https://www.flickr.com/photos/186616357@N04/49434728858/in/dateposted-public/

After a short drive in the 40s mine got up to temp fine. Your thermostat may be stuck open.

I put a thermostat in it, but maybe this one was just faulty out of the box. I’ll change it again and report back.

Test the thermostat: Put it in a pot of boiling water. If it opens you know its not the problem. If it doesn't open return it!

What’s your engine code?

The thermostats that they put in these trucks are junk, I've had one expire every 30k miles.

I'd buy a new thermostat and gasket, swap them and try again. It sounds like the one you have is stuck open.

This shit happened on my m3s and other BMWs.

Just seemed odd cause I’ve never had one fluctuate so wildly temperature wise and was wondering if it wasn’t the temp sensor. But I’ll get another thermostat and report back if that fixes it.

How's your heater? Is it blowing hot air like normal or just kind of lukewarm once the truck SHOULD be warm?
