Ford Super Duty (1999-2016) :: Losing Heat When Let Off Throttle / Come To Stop?
Mar 13, 2017
I have a 06 f350 6.0. I'm losing hear at times. My temp gauge is right in the middle like always. As soon as I let off he throttle or come to a stop the heat turns cold and blows out cold air!

I have a 2000 7.3 just replaced the alternator little over 2 months ago old one was wore out...heres my problem the night before last I was coming home and started to lose charge and made it home..shut the truck off and tried to restart and it would just click due to low volts.. the next day tested both batteries and they tested weak so I just cleaned the battery post and the cables..and started up and ran fine all day.. last night on the way home started to lose volts again got all the way down to 8 volts showing then all of a sudden it kicked in went back to normal.. and now today started to do the same thing by losing volts but now its dead but the batteries still test weak with no discharge under a load

I have a 2008 6.4 f-250. It has 139,00 Miles and I have a problem with the truck losing coolant and overheating on the interstate. When cruising 75-80 my truck will sometimes begin to puke coolant from the degas bottle and my cooling fan will begin to run. Engine coolant temp once spiked to 240 degrees before I could get off onto the shoulder. Around town the truck does fine although I do notice a loss of coolant but no overheating issues what so ever. I have the Dpf Deleted and Egr coolers are off. I run an H+S on a mild tune. Is there any other thing that could be wrong with this truck besides head gaskets? I am not looking forward flipping that bill. Trying the exhaust all other possibilities first.

99 F-250 SD 6.8 had an issue with it while moving from Del to Phx, Az. Found collapsed air cleaner element. It looked like someone stepped on it. I replaced it as well as the MAF. This fixed the issue. This was 350 miles into the trip. The truck seemed to be down on power as it didn't want to pull my trailer up any type of grade except with OD off. Around 2K miles into the trip in developed a random misfire with no codes. I am at my final destination and the misfire is worse. I am not showing any codes at all or pending either. It is a bit toasty outside to be out there diagnosing issues, and I won't start changing parts randomly either. I have a NGS scan tool with the proper cards.

I have 03 f250 v10. just replaced the engine and got everything all connected and started it up and it idles great...the problem is that when you press the gas pedal it starts to drive but then it looses power and acts like its missing. cant get it to go 30 mph. While keeping it floored eventually it gets up to 2000 rpm and then starts to pick up speed.

I was driving to the store today and about halfway there the truck kept the same rpms but I was losing speed. The wrench lit up on the dash, checked the tuner (nothing out of the ordinary) so i pulled into the nearest parking lot and shut her down. The tuner is just there for my dpf delete and is set to "no power" or stock settings. It's a bully dog triple something or other. I don't race the truck or work it very hard for that matter. Basically a work truck that hauls more people than trailers.
Lifted the hood, checked the tranny fluid level and the stick was dry as a bone. Thing is, it's winter here and i haven't noticed any transmission fluid leaks anywhere ever. I'm gonna head to the local (two hour drive one way) parts store for fluid in the morning with my dads truck.
I'm wondering where it went? did it burn up or leak out and I didn't notice? Just wondering where to look first when i get it back home. Or did i simply fail in my maintenance checks (i admit i change my oil and fuel filters religiously but haven't checked the trans fluid) and it ran out??

Just noticed something funny yesterday while flushing my radiator. I have an 04 F350 with the 6.0. When I have the heat set to come out both high and low vents, the A/C compressor also kicks on. The pipes by the passenger side firewall get cold. If I set the heat to just come out high or low, it turns off. This is not with the defroster on. Why does this happen? Is it supposed to happen?

I have another very odd problem with my 2003 F250 7.3 PS with 206000 miles on it.
I am visiting my parents and every time I go thru this certain area my truck will act up. The first thing that happens is the truck starts losing power and then it starts bucking like water in the fuel or the cam position sensor is giving out.
WHAT I HAVE DONE SO FAR: I have drained the fuel filter assembly ( no water ) and a new cam position sensor has been installed (about 5000 miles ago, I even put old one back it to check it out same results). I have driven the truck all over the place and don't have an issue except in this ONE spot. I am beginning to think there is some kind of high powered RF going on in this area causing my truck to act up. I am thinking of hooking up my autoenginuity scanner up to it and hopefully see something going on.
Is there anything I can do to block this out if it is a RF problem. I think it is effecting my Pcm/ECM for then engine causing the truck to act up.

I have an 03 with a 6.0 diesel, going down the road and started losing power and then died. Won't start, and I don't have a scan gauge. Several sources said ipr valve, and from videos on youtube I thought may be a good place to start. I bought a socket and pulled the valve, to check the screen. There is no screen whatsoever on the ipr. The oils clean, as I had changed it about 200 miles ago, and I ran a magnet in the hole looking for a screen, couldn't find anything so I used my fluid pump in the hole. No trash, screen or anything. Do some ipr valves not have screens? What would be my next step??

1999 F250 super duty w/ 5.4... My truck seems have issues keeping speed on the interstate like its not wanting to switch gears on time. Its auto by the way. Gotta little hesitation in the idle exhaust due that I have several leaks in my exhaust. Could that be the problem?

I have a 2007 6.0 with 260k on it losing gauges and radio intermittently while driving. Lately 2-3 times a day, lasting 3-4 seconds a time.
I have heard it could be the shift lever, instrument cluster, fuses, etc. I have kind of ruled out fuses based on the behavior of the failure.
Looking for a second opinion before I start taking the dash apart or send it in. The truck just can't be down for a long time right now.

2002, F250, 5.4, ZF6, 140k.
My heat only blows through the defroster. I was looking for my vacuum pump, but can't seem to find it. I find plenty of diesel threads where they show it, but mine isn't in the same location. I can actuate the diverter by hand and it will make the heat stop at the defroster and come out at your feet.
I have attached images of my rig.
Were to look for the vacuum pump? Any key spots to look for failed vacuum lines? What is this?
This is where most threads say the vacuum pump should be.
This switches from defrost to floor when operated manually.

I have an F-250 Ford, 2006, 6.0 turbo-diesel. Started noticing that my heat only works while running at 70 mph or more and the turbo is at around 15-20 psi. Now that it has gotten cold it is definitely an issue. Truck does not overheat, I am not able to feel heat on the hose after control vlave and I do not feel any vacuum on the line (grey) to the control valve. I have checked for leaks, changed out the fill cap, checked anti-freeze level, pulled control valve just to verify its position when opened (which it seems to stay open). It's getting really cold in the cab of that truck now.

I have been having trouble with my 2008 Ford F250 4x4, 6.4 liter diesel transmission. SCT tuner, 10" lift, egg delete and dp delete has been done. I have been losing power mainly in reverse but have noticed that the transmission hasn't always been going into the last gear on the interstate. Code PO741 would come up. The other day the shifter was stuck. So I played with it and found that the cable on the transmission had fallen off. After replacing it. The transmission wouldn't go into reverse but has been doing semi good in forward. Well I have been limping it around until today when I was going down the road and it completely stopped pulling. Now no matter what gear I place it in, it will on go in reverse. What could be causing these issues or where to even begin to start looking?

I have a 2015 SD with only 4100 miles on it. This has happened to me twice. Both times, traveling slowly at idle or just above. Anyway, tried to give it a little gas, and -----nothing. Lightly pumped the throttle a couple of quick times and back on line. The motor didn't die, but there was no response to the throttle at all. The first time, I thought maybe it was something I did. Then it doesn't happen for a month and a half and then again, in heavy traffic in the rain. Haven't had my first service yet, and you can bet I'll tell them about it. Almost felt like a two-stroke that had loaded up?
