what is the best way to clean the epbv and what are some symptoms that would clearly indicate that it needs to be cleaned . thanks

 

I just cleaned my ebp sensor and the tube that goes to it. Is this what you mean?

 

yes what did you use to clean it and how hard was it,how dirty was it.did you have to worry about damaging the sensor when you un did it

 

It is easy to do. The sensor is right in front in between the engine and belt. unplug the connector from the sensor and then use a 1" socket to remove the sensor. Then use either a 5/8 or 9/16(I don't remember) wrench to undo the tube. You might need to use a size smaller wrench to hold the nut on the sensor bracket(I did) so it doesn't move when you loosen the connector on the tube. The other end of the tube is the same size wrench from under the passenger side of the truck. You can trace the tube by running your hand along it to find the other end. Once it is off you can use compressed air or someone on here mentioned using .095" weed eater line to clean it out. You will probably find alot of soot in there, I did. Put the tube back on and i used a small awl to clean the sensor out, it is made of metal and i figured i had to get the soot out of there or it wouldn't work. So i cleaned it and put it back together and hoped it didn't get damaged. I heard ebay is the cheapest to get new sensors.

 

what are the symptoms that would make you want to clean it

 

If your EBPV is still on when pushing on the go pedal, then it is time to clean the tube. It should de-activate when you hit the brake pedal. I noticed mine wasen't working correctly last winter when I would go to work in the morning, and about 32 deg out. The EBPV would not release, the truck would only go about 25 or 30, and no power at all, and alot of Hissing. After I cleaned the tube and sensor, it now works fine. I also had to replace my tube this spring. It seemed to have a crack in the line that was rusted out. I just used I believe a piece of 5/16 brake line to make me a new hose.

 

I went to Puredieselpower.com and got the EBPV delete to make the truck quit recognizing the sensor - When I talked to a mechanic, he said the EBPV was really useless, so I deleted it.

 

The only reason we have it is to speed engine warm up so that the cabin heat gets hot faster, and that is from Ford. I would tend to believe that our brothers in the north would not consider this as useless as we do down here.

BTW: The square 0.95 weedeater line does work very well

 

Evidently the mechanic dosen't live in cold climates, or dosen't haul with one of these trucks with the EBPV hooked up as an exhaust brake, because it works very well for this. But to each their own.

 

how long is the tube and what is the inside diameter of the tube is it made of stainless steel why does it get clogged thanks and it is cold here -30 degrees celcius thanks

 

I'd say about 1/4" ID its about 18" long with about 5 bends in it. it is a dead end sensor line and Soot from the exhaust builds up in it over time

 

It is probably about 18" long(these are just rough, i didn't measure when i had mine off). About 1/4" inside diameter. It comes from the passenger side exhaust manifold and goes to the sensor. I would assume that the soot coming out the exhaust gets blown in the tube and has nowhere to go once it gets to the sensor.

 

alan bet me to it.
