Turbo Pedestal for 99

I finally had enough and brought my truck into the local Ford garage to get my rig scanned. I have had a lack of power and poor fuel economy. What they told me was that my EPC valve on the turbo pedestal is sticking. They told me that the pedestal needs replacing and that should take care of my problems.

I'm a newbie and am not very mechanical, so I'm looking for some good advice on where to get a good deal on a pedestal. Also, how long should it take to replace this part by someone who knows what they are doing?

Thank You!!!

Your valve is sticking its actually actuated by the pedistal. Oil pressure moves a piston that moves the actuating arm to open and close your valve. The actual valve is located on the back side of the turbine. You have a couple of options: You can have them pull your turbo and clean the valve or you can do that yourself, or you can move the actuating arm by hand to open your valve and unplug the soleniod so you valve no longer will close. Also you could elimininate the whole vavle assembly.

From what I understand the only reason for the valve is to produce heat in the cab? Is that true? So, if I moved the valve open by hand, will it stay open on its own or is there some kind of set screw or bolt to keep it open or will it just stay open by itself? I assume the connection for the solenoid just needs to be unplugged? Only problem with heat in the cab is that I live in Northern Minnesota where it gets colder that a witches t@t in the winter. So, will my cab not heat up or will it just take longer to heat? Thank You!!!

Its a valve that closes when the temps are cold to put a load on the engine so it will come up to operating temp sooner. I got rid of mine last winter. It takes 5-10 minutes longer to get the truck up to operating temps, but its worth it over the annoying hiss and poor fuel mileage,and no power. Here is a pic of the turbo pedistal. If you look at the back left side you will see the arm that moves the valve. With the truck off move the valve so its open and unplug the 2 wire plug with a wire clip that plugs into the front of the pedistal. You can see the white plug on the front that is where you need to unplug from. Once its unplugged your ebpv will no longer close

OK, so one last question... what way do I move the arm to open it? Sorry for being such an idiot, but I am really unmechanical and I usually mess things up when I try, so thanks again for the help. So, up or down?

I just wanted to thank everyone who gave me advice on how to get my truck running better. I unplugged the soloniod and pushed the arm in to open the valve and BAM, problem solved!!!!! You guys are GREAT!!! Its nice to have a site like this when I am having problems, especially when I am not mechanical. It was an instant fix to my loss of power and poor fuel economy. I haven't gone enough miles to check my mpg yet, but I can tell from my gage that I am doing way better. On my last tank before the fix, my gage was just above 3/4 with 100 miles and now I'm over 100 miles and the gage hasn't moved off F. One other thing, I used my hand held gps to check my speed. I have 285's instead of the 265's. My speedo is off by 1.5 mph so at say 60, I am actually 61.5. As far as th odometer in 100 miles the gps was at 101.5, so not a real big difference. THANKS!
