Water Separator Indicator Light/Draining Questions

Hi All: I've been away for abit, and so please excuse if these questions have been asked recently. BTW - I have a 2008 F350 SRW 2WD CC SB PSD auto.

1) Can it cause a problem if I just wait for the water separator indicator light to come on before draining?

2) To those who have racked up a few miles on their 08: have you noticed the frequency that the water separator light comes on (i.e. approx. every 1000 miles, every 2500 miles, etc.)?

I know it's considered good practice to just drain monthly in all cases. However, the reason I ask is: I haven't bought my 5th wheel yet and have a daily beater, so I only take the truck out for a short spin on the weekend. I've only put on 1000 miles on in 4 months so far. My indicator light still hasn't come on. Since my truck is a 4x2 and lower, I cannot fit under the cab step rails without lifting the truck (I tried, too fat!). Also, I haven't yet bought ramps or jack stands. So it's not exactly convenient to do so until absolutely necessary.

Thanks and Happy New Year!!!
Gary

Re: Water Separator Indicator Light/Draining Questions

To answer your first question, no. If the light is not on then theoretically there is no water getting past the separator to cause any harm. If the light does go on, you may still have a little more room for water in the collection chamber but don't wait too long to drain it just in case you picked up a significant volume of water.

Your second question about the frequency of the light coming on is one that cannot be answered accurately because it all depends upon whether you actually collect any water in your tank and how quickly it gets picked up from the tank. You might pick some up with a load of fuel or your truck might only produce an ounce or two per year from normal condensation. Unless you have a problem with the light coming on I would leave well enough alone and drain the separator during normal service intervals. I always drain the fuel water separator for my customers when I am changing their oil since it only takes a minute. For most owners, that interval should be sufficient.

Re: Water Separator Indicator Light/Draining Questions

With over eight years experience with my current PSD, I've never had any water drain out when I drained the fuel filter/water seperator. So a few years ago I stopped draining my fuel filter except when I change the filter.

Yesterday I drained mine, and changed the filter, for the first time in about a year. It didn't need draining because not a drop of water came out - just a pint or so of pure, clean, diesel. But the filter was way overdue and needed changing really bad. [img]/forums/images/%%GRAEMLIN_URL%%/blush.gif[/img]

So if you always buy your diesel at busy truckstops, and fill to the cap when you fill up, and live in an arid climate, you probably won't collect much water in the water seperator.

Re: Water Separator Indicator Light/Draining Questions

Another quick point I forgot to make was that regular draining will also reduce any sediment that may collect there as well along with preventing plugs from seizing from not being removed. Now I realize that the HFCM for the 6.4L has a valve instead of a plug so exercising it will help prevent stiffness or binding that many 7.3L PSD owners experienced over time.

Re: Water Separator Indicator Light/Draining Questions

My truck has 8700 miles and I've never seen that light.

Re: Water Separator Indicator Light/Draining Questions

Well I have a 6.0, but it has 131K miles on it now and I have never seen the light come on. I have resorted to draining it only when I do an oil change now.

Unless I am traveling I always fill up at the same truck stop. They get in 2-3 tankers a day of fuel, so it's a busy place. [img]/forums/images/%%GRAEMLIN_URL%%/smile.gif[/img]
