Drain Water Seperator Light Question

[johnny9r]

I recently bought a '08 F350 used and today the drain water seperator message came up on the dash board. I looked in the manual and it pointed me to the Powerstroke addendum, which of course didn't come in my manual package. I googled around a bit and searched hear but can't fine any information on where this thing is at and what I need to do to get it drained. Any help is appericiated

It's right under your driverdoor inside the frame rail. There is a yellow 1/4 turn valve that will drain the water.

Is anyone draining this on a regular basis on just when the light comes on?

i do it about once every 2 months when I can remember. If you use good fuel, then you dont have to do it once a month as recommended.

I do it every other month and my light has never come on.

Never had the light come on. I do it every couple tanks -- never had any water though.

If you live in a cold environment, the water that you are trying to drain out will gel. If you hit it with a small blast of air, it will drain. You have to be very careful doing this, or you will get a diesel bath. Somebody recomended the canned air containers that you clean your computer with to keep pressure down. I have used shop air full power and got a bath (even though it was just a quick tap of the trigger). If you turn your pressure down to say 10-20 psi, I think it would get the job done.

6.4 is a piece of trash!! Yes, light came on over and over. Water or no water. Then truck quit. Wiring harness shorts out on 2008 models at about 50k. DO NOT BUY A TRUCK that they have to pull the cab off of to work on the engine. I am demanding a total refund...it is not right for the public to be guinea pigs for a product. Even ford is getting rid of the navistar engine. Actually the main problem is the particulate filter.

I like it. This truck was engineered to have the cab pulled off as an improvement on the 6.0L. 6.4 is a big engine, no room to work in there. The particulate filter is garbage, but that isnt ford's fault, that's and EPA mandate. Big rigs are getting them too. Check into the dispute at the LAX harbor. Truckers over there are mad!
