Re: 2002 F-250 7.3 - hot at idle - capacity question & help wanted

well, new fan clutch definitely exhibits different behavior. stays locked longer on startup, locks faster while idling. idle vent temperature performance is better, but still not in the 40s. maybe high 50s. at speed performance remains phenomenal, 40F all day long. given that every component has bee...

welp, tenatively, think bohica2xo was correct. i put the new fan clutch in friday. definitely more air movement at idle, but this clutch actually unlocks after you start driving. it holds on longer than the original clutch, so definitely some different behavior. haven't had a high 90s day since frid...

Ah, the old defective return received from RockAuto. Because of the distributed wholesale nature of that operation, RTV items that don't get tagged get re-shipped to customers. Just the nature of the system when you run it with the lowest possible operating cost. They do usually make it right. All ...

Verify the recirc door is fully closing along with heater control valve operation. Vent discharge 30deg under ambient in non-recirc mode rings a bell as "normal" on most systems... which is where you are at idle. A partially open recirc door will often cool at highway speed but not slow/s...

"after all of the above, @95 ambient, ~60F air at idle, ~39/40F" apologize if i was unclear, was trying to say: @95F ambient, i get: ~60F air at idle (unhappy) ~39/40F air at speed (happy) 39f rolling down the road, 60f stopped. AIRFLOW. Bad Fan Clutch. Missing shrouds, seals or air dams....
