This is for the adapter and mechanical fan clutch this is not a bullet proof diesel adapter and the fan clutch is not a Hayden but both are a quality alternative.
7.3L Fan Clutch Upgrade for 6.0L Powerstroke Trucks/Vans
Upgrade your 6.0L Powerstroke with the proven 7.3L fan clutch for improved cooling performance and reliability. Keep that 6.0 cool this summer trucks tend to run 15-20* cooler all around
This fan clutch engages at a lower temperature (around 200°F) and stays engaged longer than the factory computer-controlled unit. The result is better cooling capacity, improved A/C performance, and cooler engine temperatures under load or while towing.
Because the fan is more active, you may notice increased fan noise compared to the stock setup. If extra fan noise doesn’t bother you and you want maximum cooling performance, this is an excellent upgrade.
