I hope the dealership didn't screw you. For what it's worth, I just crossed over 10,000 miles and my fuel filter is at 50%I may have a more sinister reason why the indicator was down to 0 % so quickly. I changed the fuel filters and have monitored their life and so far it has not dropped below 99 % in 2 fuel fill-ups. Either I got a batch of bad diesel fuel, always a possibility, or the dealership did not change the original filters and just reset the monitor and charged me for it. I usually do not think like this, but what the truck was originally in there for was also not fixed and I went around with this dealership about that. I did not get a warm fuzzy that they cared about me or my truck. Hopefully I will have to wait a long time before it reaches 0 % again, but when it does, I will attempt just a reset and see how long it takes for the monitor to reach 0 %. My guess it will be similar to what I just experienced.
ThanksThis may help you guys out. I picked up ACDelco TP1007, a 27mm (1 1/16") socket, and went to town. Easy job and only took me 15 minutes. Reset to 100% took 5 restarts, but this may not be the standard.
I've done it, simple, 1st thing the manual doesn't tell you is there's a little yellow plastic screw between the 2 filters, have a catch pan ready and unscrew it, that will drain the fuel from the 2 filters that way they'll be no mess when you take each one out, you'll end up with around 20 ozs. of fuel to dispose of (charcoal lighter)I am wondering how difficult it is to replace the fuel filter in my Colorado Diesel. Or do I need the dealership to do it.
