FIRST TEST POST SHORT WATER PUMP SWAP
so 195* Thermostat, Short Water Pump, no bypass hose (heater core delete, remember) and running only water
RESULTS = Favorable but not there yet
the truck did not get hot idling in the garage after 15 minutes like it used to, it used to reach 205* just sitting there, I let it idle for 40 minutes and it just eventually got to 190*
so I took it for a TEST DRIVE...
and gosh darn it I saw it climb to 215* that aint right!!!

Classic symptom of a clogged radiator. Stays cool at idle, and gets hot going down the road, under load.
