fan clutch problen after egr delete and new oil cooler

[greg_j_72]

i just installed the sinister egr delete kit and now am finding that my fan is not working properly, i left the egr valve hooked up but out of the intake, i also have put it in intake to see if it made a diference. it didn't. the fan clutch is brand new also, dealer said it was bad so i did all 3 things at once. any thoughts?

oh btw, it is an 05. i have read up some on this issue but all seem to pertain to having the valve unplugged. but haven't found much on this problem with it plugged in. maybe i have a defective fan, its a dorman.

Its possible there is a difference in the pigtail of an oem vs aftermarket. let me guess fan speed code?

The proper way to verify its function is to rev the engine up to 2500 RPMs and maintain that engine speed as you active command fan clutch duty cycle from 0% to 100%. At 100% duty cycle, the fan clutch speed (in RPMs) should almost instantly climb to minimum 2800 RPMs. You will obviously need an IDS (or equivalent scan tool) to do this. Just my .

it has a p0528 code in it, i'll check the pin location and color tonight. don't have access to an IDS that i know of so connecter is going to be my first option

Where in the IDS do you active this function?

I had a truck today with 0528-60 just finished installing a new fan clutch and would like to check this.. Have tried under datalog /engine with no luck.

Thanks for your help!
