WIF indicator
Well this morning got ready for a one day trip to the cost to pick my sister up for her back surgery. I checked everything on my 04 350, well everything looked good, started the truck up and a few seconds later the WIF light came on.
Well instead of taking it to a shop I turned the engine off grabbed my shop light and allen wrench ( I still have the OEM WIF nut for now) got on the rain soaked ground got the water to drain out and it had water, luckily after 5 seconds it had all the water and now the diesel is running good.
This weekend I already planning on changing oil/fuel filters (hopefully get the new drain nut) and air filter and maybe something else but I don't know yet.
Luckily I know now my WIF sensor is working.

In the 6 years I've had my truck, I've never the WIF light come on, I guess that's a good thing, but I've wondered if it really works myself. I always drained the water every oil/fuel filter changed, however since I had 2 injectors replaced last summer, I drain the water once a month now, just to be safe. I know it's probably a little overkill, but ya never know.

WIF light has been coming on intermittently on my truck the last few days as well. I used it as an opportunity to upgrade to the (International part # 2589259C91) drain plug. It looks like it is machined from a solid piece of brass, and the machine marks are even polished out of it. Its like jewelry for the truck.

In winter, I drain mine once a month. It gives me a "heads up" to the quality of fuel I've been purchasing. The only bad thing is it's tough to squeeze my fat AZZ underneath those polished cab steps, I may just drive her onto ramps next time.
