Bummer. New Tstat isn't going to get here until next week. Le sigh.

I guess this will give me time to change fluids!

Truck came with a few jugs of Valvoline 75w90 gear oil, should work just fine right?

Ugh, not pleased!

Swapped in the new black tstat from Lucky8 and basically still have the same results First off, i'm pleased with myself in this endevor for only losing about a few cups of coolant on the ground! Started the truck, temps crept up to 215 and then i shut it off -- heat was on full blast and the air coming out was meh hot. I should also note that i installed a new temp sensor on the lower intake manifold while doing my HG job. All parts are from Lucky8.

Busted out the thermo gun after i shut the truck off and here is what it read.

Ambient temp was in the low 80s, truck is parked on a slight incline with the nose facing up.

Top 3 radiator hoses were between 150 and 170
Lower WP hose was 135
Radiator: From the engine compartment side -- Top left 121 Top right 102 Low left 97 Low Right 95
Lower rad hose was 97
Tstat: Upper half was 138 and lower half was 104
Heater core hoses: Going in was 140 and coming out was 125

In contrast, here are my readings before i replaced the radiator, WP and tstat:

I shot the temps from the back side of Rad (the engine compartment side)

Upper left corner of Rad: 190
Upper right corner of Rad: 122
Lower left corner of Rad: 155
Lower right corner of Rad: 100

Upper cooling hose from bleeder T to Rad: 171 @ Rad and 140 @ T
T to block: 167
T-Stat to T: 178
Rad to T-stat: 114
WP to T-stat: 155

Expansion tank: 175
Heater core hoses were both 133


MagPie is cooling off right now, so hoping she burps A LOT BECAUSE I AM OVER THIS SH-T

Any insights, thoughts or money donations would be greatly appreciated!

Isn't there a way to chuck the external t-stat garbage for a conventional setup? Have you checked for exhaust gases in coolant?

You mean the inline mod? Sure it can be done.. I guess what I was thinking about in the middle of the night is that the coolant temps at the upper half of the tstat aren’t getting hot enough to open it. I was seeing 150-170 yesterday, tstat shouldn’t open until 178. Mean while the engine is overheating. Ugh.

Right?

Havent done the gas coolant test.

did you open the bleeder screw before you start it up in the morning (while the truck is stone cold) to see if there is any air there?
