added UD pulley's, need to change anything?
 

hey bill and corey,

i just added UD pulleys, is there anything i need to change? like idle speed or anything?

thanks

Yes, go into CO and bump the idle up 50-75 rpms. With everything on you don't want to fall below 13.0 volts on the voltage pid.

ok thanks, i set it at 65.

is that all?

also i dont know if anybody can help out about this but the gryphon is showing i have 2 DTC's

1. P0480 Fan 1 Control Circuit

2. P0528 Fan Speed Sensor Circuit No Signal


i dont get where i would check for this, i have the harness connected that connects to the fan and there is nothing else unplugged

any ideas?

I don't know what to check either. Sounds like the system thinks you have e-fans, but you don't show that you do. I don't think there's any kind of monitoring for the clutch driven fan.

Try clearing the codes to see if they come back.

Make sure all connections are tight.

Check to make sure there isn't a magnetic pickup sensor on the old waterpump pulley.
I haven't dealt w/ to many 2008's yet.

ok i will try clearing them. im positive there is only one connection to the fan and it is plugged in.

also there wasnt anything on the water pump, but i will make sure there is nothing around it

Ford changed stuff on the engine fans, starting ~2006 or 2007. Even though the fan is driven by the water pump pulley as before, the clutch is controlled by the PCM. And it appears to be more than just on/off control. Looks like the PCM outputs PWM (pulse-width moulation) which controls how much the clutch locks up, which in turn controls the actual speed of the fan. It's a closed loop system because the fan then has a sensor that reports its RPM back to the PCM. There's DTCs for when the PCM commands the fan clutch to engage and but doesn't see an increase in the reported fan speed.

Beat me to it!
Better description than what I had to offer!

Where you get your ud's from?

Ok, so what was the ticking sound?
Was it something that wasn't connected correctly and wore off or broke?
I see you got them from troyer, good choice!
When the fan was removed no wires got accidently yanked on? Twisted?
Worst case scenario on going to the dealer the truck may go into a limp home mode but if it hasn't by now I wouldn't worry about it. Just drive real easy.
