Ford Super Duty (1999-2016) :: 2008 - Losing Coolant - Overheating On Interstate?
Jun 3, 2014
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.

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?

Im running an 2008 F-450. And towing a goose neck trailer with the total weight of 12,000, including the car in tow. We were traveling from Cleveland to Columbus last week. Traveling south down Rt. 71. Which has some subtle gradient here and there. But nothing extreme. I haven't tried any mountain runs yet. when i started noticing the temp gauge climbing from middle normal range to high normal.
It would then kick out the cruise control. It would cool off after about 5 minutes of slower driving. We were only traveling at 65 mph. Outside temp was about 78 degrees. I shut off the A/C and it seemed to improve. Should it be over heating like this. The capacity of the 450 is 25,000. I am at half that right now. Are these truck prone to heating problems. And if so. Is there a high performance supplement cooling system.

I have a 2008 powerstroke. Dpf and egr have been fully deleted. SCT tuner seems great and have had no issues since installed 6 months ago. I recently hooked up to my camper and headed up a mountain pass. As soon as I started uphill the engine overheated. I allowed it to cool and tried again with the same result. Eventually had to unhook and have another 6.4 (this one being a 2010) pull the trailer the rest of the way. Haven't had any heating issues since unhooking.

I have an 06 F-250 Lariat with the crew cab. Even though the windows are tinted, the A/C struggles to keep the cab at 70 degrees on any given sunny day oer 80 degrees outside.
As long as you're driving on the interstate, it blows cold, but when slowing down (like a traffic jam or a stop sign) the air gets warmer and has a funny smell (like it's wet).
When I got the truck it had just gotten a new A/C compressor (160k miles). It stopped working last summer (180k miles) so I had the truck at the Ford dealer here and they replaced the A/C compressor, condenser, pressure regulator and dryer...basically all A/C components under the hood.
They tell me its working fine, but I find that hard to believe. No Ford I've ever had has had trouble keeping the cab ice cold even on the hottest days... How are your air conditioners working? Do they keep the cab cold? What I should look at?

I have a 2008 F250 which has been a awesome truck. Very few issues except for one that no one can seem to fix. Its regarding my brakes and a mysterious reason all of them have to a degree locked up and smoked the pads rotors etc. I now have 80k on the truck and have replaced all brakes once and now the front left have locked up for a second time. The scenario goes like this:
So i'm driving along and if the front brake locks up I can begin to smell it. So I pull over and smoke rolls out along with the overheating popping sound from the effected brake. Rear brakes usually are not found until I stop which i get out and then can smell them. Funny thing is the brakes have locked up when not towing. Also, I have never had more than one happen at a time. So as today all brake pads and rotors have been replaced and now the left front has overheated again. From what I can tell the caliper just doesn't fully release. What could be causing this?

I purchased a '15 KR cc sb some time back love the truck! It came with a leveling kit and tires were changed to Michelin 35's on stock rims.
The issue is that on certain sections of concrete interstate the truck "bucks" back and forth...a lot.

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?

I have a 99 S10 4.3 2wd. Last week on a 5-6 mile drive it overheated, and it turns out the coolant was somehow almost a gallon low! I topped it off and all was well for nearly a week. This weekend I was driving and suddenly could smell a strong coolant odor. The temp gauge began to spike and when i pulled over and popped the hood it was clear the coolant was finding its way out but not through the overflow or radiator. When it cooled down and I added water/coolant I could see the coolant coming from the block or near the block. Also, when I let it run for a few minutes i could see the fluid "spraying" out from what appears to be near the pass. side valve cover maybe near the intake manifold...The oil looks good, so I'm not sure it's the head gasket. Not sure where to go with this.

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??

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.

My Son drives a 2012 6.7, and just recently it started overheating bu only under acceleration? It runs cool while idling, and once you reach the desired speed, it cools back down, but under acceleration it overheats? We've checked the obvious (coolant etc...), but can't figure out what it would do this only under acceleration?
