I think I would start with the clutch fan. Check and see if it spins freely when cold and engine is shut down.If it’s locked up all the time it will make it run cooler and burn more gas like you described.

I’ll give that a look before/when I fire it up after work. I was able to stick my hand down there this morning and it was spinning slow enough for my hand to rub on the blades easily

Changed out the thermostat and now she’s holding running temperature really well. Needle stays rock solid right before the center of the gauge. See if that fixes the fuel consumption issue tomorrow

I'm 100% sure it will. Engine runs with a rich fuel/air mixture until optimal operating temperature is reached. If it's never reached you will burn significantly more fuel at all throttle positions.

I’m glad you found the problem. Always start out with eliminating the obvious things first before throwing parts at it. I wonder if your loud fan like noise goes away now also?

How to work safe - stick your fingers into a running engine fan assembly. If your fingers stay intack the clutch is disengaged. If a banging sound accompanied with blood flying everywhere is heard, the clutch is stuck on. Head to the ER and stop by the auto parts store on the way.

Riding down the freeway this morning I averaged 20-21mpg at 70mph. As far as the fan noise it seems a bit more quiet. Maybe I was just exaggerating that because I knew something wasn’t right. Held running temperature perfect the whole way to work so as of right now I think everything is ok. But I’ll find out over the weekend driving it around.

Works every time hahaha. On a semi serious note I made sure to “check the clutch” on the safer side of the fan rotation so my finger would just bounce off and not get smashed to bits. Definitely not a good way to do it but I’ve been in this for long enough to know when not to do something for safety reasons.
