Thanks.
Yes the fans are working.
I just had got to open the cap for a minute or two and the truck showed up. The coolant was starting to rise and overflow and I was hoping to see it not drop but the driver was ready to go. I guess if the Tstat opened the level would drop eh?
I was at a light and the chime went off and the dash light was on. I took off and got some wind on it @ 60mph and it started to cool down but the next light it went back up and was harder to get back down so I parked her.
I may just pull it and boil it up to 225°F I guess.

If you pump failed, you would have little to no heat into the cabin, because there will be litte water flow thru the heater core.
If you T-Stat Failed, you can use Cabin Heat to somewhat cool down the engine.
Usually when a T-Stat fail, when you pull it out, it falls apart. And it is a $11 part, and 15 minute job to change T-Stat, maybe you should just throw one in and see if it help.

Pulled the t-stat and gave it the hot water test. They are 195°F units.
It opened a little maybe dropping 1/8 to 3/16" not even half as much as the new one.
You could really see the difference and the new one compressing the spring pretty good, but the old one just cracked open -so-to-speak.
What do you think. Pop it in and drive her?

Thanks, I was surprised to find several videos on the job.
When I pulled the t-stat housing back and removed the t-stat from it, not much fluid poured out.
So I fired it up hoping to see the pump move some fluid but nothing pushed out.
Heck, I may just consider it a preventive maintenance thing and do it I guess.
Should I have seen fluid pump out?
