Ford Super Duty (1999-2016) :: 2003 F250 SD 4x4 - DTC Codes P0171 / P0174 - Loose Fitting Oily Hose?
I've had DTC P0171 & P0174 (lean in bank 1 and lean in bank 2) for a few weeks now (check engine light cued me on it). Autozone scanned it for me. It's on a 2003 F250 SD 4x4 5.4L.
My first step was to clean the MAFS. Light came back on in about 30-40 miles. I then replaced the MAFS. 30-40 miles and the light came back on.
My first thought was disconnecting the battery wasn't resetting the comp and thats why the light was comming back on.
I went and picked up an Actron cheapy OBD II Scanner today at lunch. Cleared the codes with the scanner and drove back to work.
Checked the codes when I got back (no light on but was curious) and it shows P0171 & P0174 pending.
I've checked and the dipstick is seated properly. The hoses on the air intake appear to seated properly as well. The top hose is a pretty loose fit but it was seated all the way down. The top hose was oily. Not sure if this is normal or not. Could the loose fitting oily hose be the culprit?
Also, what is the lower hose? It comes off the back of the air intake and goes to the driver side valve cover. I know it's not the PCV hose as that is on the passenger side valve cover....right?

My '01 Super Duty 5.4 has an overheating/heater problem that the dealer can't seem to fix. I noticed my heater was blowing cold then a few miles later it overheated pushing coolant out of cap. Next day drove fine to Ford dealer who replaced my heater core, thermostat, reservoir cap and a hose. Drove it for a day till the exact original symptoms occurred again with a gurgling sound in dash. Dealer kept for a week pressurizing system but no leaks found. Replaced my thermostat again and gave it back. I drove it 300 miles over a week before the exact same symptoms occurred. Brought back to dealer who said that air was in the system, added a bunch of coolant and supposedly got all the air out. Same symptoms still. Brought back to dealer that finally changed the water pump they said had a leak. Guess what, same symptoms. Heater will work fine for days then it will blow cold, then hot, then cold and sooner or later truck will overheat then just as fast cool down and heater will work again. Still hearing gurgling. Dealer said I don't have a HCV.

View 2 RepliesFord Super Duty (1999-2016) :: Hose Coming Through Radiator Fan Shroud?
Just picked up my truck from the dealer after a trans flush. While it was there I had them replace both windshield wiper nozzles. They called and told me the hoses needed to be replaced as well--- OKAY fine do it.
Come home and decided to "make sure" the trans fluid was at the correct level.
Open the hood to discover a loose black hose approximately 1/4" or so in diameter coming out of the radiator shroud directly at center of the top. The end of the hose was somewhat towards the passenger side battery.
I figured okay the tech probably just left my old windshield wiper hose on top of the motor and forgot to discard it...
I follow the hose and it appears to go in between the rubber seal for the shroud and the plastic housing. I looked back behind the fan and can see the hose twirled around an aluminum or stainless steel pipe coming up just in front of the fan but behind the numerous condensers...
MY question is two fold: Should this hose be here, or is it indeed the wiper hose that got sucked into the fan?
if it is supposed to be here, what does the end that was leaning towards the passenger battery connect to? it certainly appears to have been previously connected to something whether the washer or some other barbed fitting....

Need the fuel system diagram or schematic for my truck.
1999 250 superduty v-10 Ser# 1FTNF20S1XEC67940
Every time I run it I smell gas. I changed the f/p 6mo ago. While I was working on it I noticed there was a hole rubbed in a small hose. I assumed it was a return line (smelled gas before too) and when I fixed it the smell went away until lately. I dropped the tank,yesterday and didn't see any problems. Just need to find out what hoses go where so I can replace the hoses??
Ford Super Duty (1999-2016) :: 2008 - Upper Hose Goes Into Water Pump Leaking?

View 2 RepliesFord Super Duty (1999-2016) :: 2002 F250 - Steering Pump Filter - Which Hose
I have put a new steering pump on my 2002 f250 and all new hydraulic hoses. I plan to install a steering pump filter on the system to protect it from anything that is not steering pump fluid.
There are two intake ports to the steering pump. One is near the bottom of the pump and takes fluid from the steering pump cooler after it has left the steering gear. The other intake port is near the top of the pump and takes fluid from the booster.
My question is - which hose would be better to put a steering pump filter on? Is there anything wrong with putting a filter on both? I imagine the first intake hose is constantly circulating fluid and the other only circulates it when the steering wheel is used.
Ford Super Duty (1999-2016) :: F250 V10 - Leak From The High Pressure Hose On Gearbox?
My uncles 1999 v10 started to leak from the high-pressure hose on the gearbox. Replaced the hose which lasted for a short time but is now leaking at the same spot. The hose swivels, is this normal, seems like a dumb design for a pressure hose. Also is there a certain trick to doing this hose? He also insists on using PS fluid instead of the ATF it calls for. Could this cause a problem with the seal?
Edit: Also the truck has been lifted on 35s since 16k miles and its now roughly at 170k. He tows with it as it is his work truck. But the truck is well taken care of.

I put on a pro comp 6" lift a few months ago and every week or two I have to crawl under the truck and tighten up that damm pit man arm nut...I can tell when it starts to get loose because the steering wheel gets sloppy...I have put red loctite and have gotten that nut as tight as I can get it with about a 3ft tube on the end of my wrench for extra leverage and still comes loose! I'm just about to grab my welder and fix it that way but there must be a better way!

I'm trying to troubleshoot a leak on my 08' F250 with a 6.4 powerstroke. It's been dripping coolant when cold pretty aggressively. Once the truck heats up, the coolant leak seems to mostly go away.
Here's a picture of the drip, it's marked by a dart, so you can see the location from the top (second pic). The radiator house connection around the engine seems dry.

What's hidden here that could be causing the leak?
Ford Super Duty (1999-2016) :: 2004 F350 Back Fired And Blew Off Turbo Hose
This is and 6.0L 04 135000 miles. I was pulling a load up a hill when the turbo back fired this was no fart hose blew off at bottom of rad, hose clamp was gone. I reattached hose but now I have lost some power and getting poor fuel mileage. I think turbo is making a howling noise at higher rpms I pressure tested the system does not seem to be any leaks, I'm assuming there something wrong with the turbo, but is it possible the hose clamp was sucked into the rad?
