451 overheating, even when moving

Got the mechanical fan on, and put the rad back, not a lot of wiggle room, hopefully that rad doesn't expand half an inch ;).

And then I ran it for 15 or 17 mins, not as hot a day today, but still mid 25, or 30 with humidex (75 to 85f?)

Temp gauge did not go past 185

Hose at top where it goes in 182-4

Hose at bottom 154-6

Thermostat housing 195-7

#1 header at the manifold 880

No puking

Previously I had:

The gauge was likely close to 200, just a recollection as I didn't note that

Hose at top 205

Lower hose next to the rad 195

Thermostat housing 212

#1 header nearly 1000

While the measured temps were cooler today, the spread between the upper and lower hoses went up from 10 to 30 degrees. I think some progress has been made with the efan pushing and the mechanical fan pulling.

I'll take it out for a bit tomorrow and see how it behaves after 15 or 20 mins driving.

Next up is to adjust the timing.
