Ford Super Duty (1999-2016) :: Temp Gauge Spiked - Cold Air Blown When Turned Heat On
Dec 28, 2016
I have been having a problem with my 2002 F250 Super Duty 4x4. It started about 2 months ago. I was in traffic (truck hadn't even been on for 15 minutes). The temp gauge spiked, so I pulled over and turned the truck off. I turned the ignition on and the gauge was normal so I started it and all was fine.
Fast forward a little and every so often about every 3 weeks it would overflow (coolant) but not get to the point that it would overheat. I changed the thermostat and all seemed good to go. Fast forward to yesterday morning. Got in the truck and left to go hunting, and I didn't even make it 10 minutes down the road when I turned the heat on and it blew cold.
I started to see the gauge creep up so I pulled over and shut it down. Upper hose was cold, lower is cold and both heater hoses are cold. After some time of waiting, I started it but the gauge kept creeping up and no heat, so I kept shutting it down. After about 5x of this, the heat worked and the upper hose got hot and all was right with the world. SO I drove it home. Coolant is new, flushed about a month ago and was running great since then. Thermostat is new. Do I have a blockage somewhere? Water pump bad?

I have a '13 6.2 with 11k on it and it's started making a weird noise since the temp has turned cold. At first I noticed a slight whistle at certain rpm's but the temps were around 0 so I didn't think too much of it since stuff gets noisy the colder it gets. Today the temps were in the upper teens and I'm noticing a new sound. From around 1000-1500rpm I'm getting a whining sound that is noticeable in the cab. It's coming form the engine since it does it while sitting and I can make the sound appear by getting the engine at the correct speed. It's louder when the engine is cold but I can still notice it a bit after the engine is at operating temps. Below 1000 and above 1500 rpm there is no noise. I never really noticed it before, but since I heard the slight whining last week I've been listening more and I know that's when you start hearing noises that you normally wouldn't pay attention to.

The truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.

Truck is a 1999 F-250 with manual climate control with A/C.
Heater core issue:
Heat is not very warm after engine is fully up to temp. Would like to back flush the heater core without damaging or making it leak. How should I do this safely?
Secondly, if I do make it leak, how hard is it to change out?

I have an 02 F250 V10. Ive always wondered about the transmission gauge. It seems to always point to the middle of the gauge range. This weekend I was pulling my car hauler up and over the Ozark mountains, and when I stopped for fuel I noticed the transmission was vomiting fluid underneath the truck (and on my exhaust creating a nice smoke bomb for everyone around me). The gauge indicated normal temps. It kind of gave me a sick feeling. I have ordered the 6.0 Trans cooler from Rock Auto and a new temperature sending unit. Do the trans temp gauge is supposed to move or is it pretty much useless?

I had a mechanic replace the temp sensor on the top of the intake in my 2001 f350 v10 and since then my temp gauge doesn't work. He replaced the sensor again and still nothing. Is there a different sensor/sender that controls the temp gauge???

My truck threw a code p1299 last night on my way home from the lake. I was towing on a huge grade and all the sudden my engine temp gauge pegged out on me and check engine light came on. I pulled over and noticed a bunch of coolant had overflown the cap but the engine didn't seem to have over heated. When I restarted the truck the engine temp was immediately normal range. I drove for another 30 min or so and the engine temp started to climb and then come back to normal then climb and stay pegged. I pulled over again and noticed the coolant level was low and coolant had overflown the reservoir. I restarted the truck and once again it was normal. I just drove surface streets the rest of the way with no issue. I suspect blown head gasket. This is a 2003 F-250 6.8L with 100000 miles.

I got in my 06 f250 tonight and my digital read out on my temp control not working. My heater and A/C works but when I turn it off my outside temp is not on. Whats going on?

My 2008 250 suddenly lost ability to adjust temp control of heat and A/C. I can adjust the fan speed and the defrost/dash vents/foot heater position controls, but no matter how far I turn the cold/hot dial left or right, the temp is the same. Even in the Max and Norm A/C setting, it's the same temp, which is stuck in the hot range.

I have had this issue with the truck 2008 F-250 6.4L since I bought it a year ago. At first it seemed as if the truck wouldn't start whenever the water temp gauge was working while she was hot. When the gauge wasn't working she would start right up like a champ. Well a year later ( have only been driving it for 6 months) a full engine rebuild, new high pressure fuel pump ( injector pump on top the engine below the turbos) she still won't start when she is hot. What the issues are.
Right after the engine rebuild I was getting the p088 code which is for the hpfp but since I cleared the codes right after the engine was rebuilt I haven't gotten the code again. I replaced the high pressure fuel pump this last weekend hoping that it would solve all of my issues and she would be like brand new again, but it didn't do anything. When I ran codes right after I installed the high pressure fuel pump I got a few codes p0684 which is the glow plug control module p0284 ( google said) gear lever y position correct but I'm unsure if that's right.
P0528 which is the fan speed sensor circuit ( that was unplugged during the removal of the hpfp and power steering pump or the radiator) p0480 cooking fan circuit ( also unplugged ) p174e out put shaft wheel speed correlation ( not concerned about that one) p008c fuel pump control circuit p008d fuel cooler system ( taken out and unplugged using installation of new hpfp) p115a ( low fuel level forced limit power) that is from trying to start while she had a little bit of air in the system after replacement) p2291 injector control pressure to low- excessive cranking ( probably from the air in the fuel system again). I cleared all those codes once I got her up and running again. Checked for codes yesterday and the only one that came up again was the p0684. Where to check next for this hot start issues,and don't know what to do at this point.

When I purchased my truck 1999 F350 about 5 years ago, I was told it was on its third transmission since the awesome 7.3 diesel engine has 200,000 miles on it. At first I noticed that going up a hill with the truck empty would cause the tranny temp gauge to climb to 250 degrees F. Nowadays when I tow my boat or carry my camper, the temp gauge pegs over 250 and the overdrive light flashes steadily when I do any hill climbs. I have had the fluid flushed several times, and I have a large fan powered oil cooler too. I also recently noticed that the tranny heated up when the truck is just idling in place.
I just got back from burning man and during the 800 mile round trip the overdrive light started flashing at least 6 times and the temp gauge read over 210 the whole time, with it pegging over 250 during hill climbs. No fluid boiled out but I am very concerned that damage is being done.
Is it possible there is a clog in a line somehwere restricting the flow of oil? Or should I replace the tranny?

Ok so here here goes I have a 1999 f250 super duty with 5.4 triton it seems to be over heating but the gage stays in the normal operating temperature range. I just changed the water pump. Could it be the thermostat and Would it hurt to remove the thermostat until I can get one...

I replaced the sensor on top of the water pump and the gauge still doesn't work. I tested the gauge by unplugging and grounding out the wire and the gauge goes all the way up. What I can try next. I didn't get a Motorcraft sensor so I'm going to go get one of those tomorrow hoping the duralast wasn't correct even though it looked 98 percent identical to the original. 7.3 lite diesel.

My F250 with V10 has developed an overheating problem. While driving, the temp gauge suddenly shoots to max, and the truck goes into limp mode. Turning off the truck and ignition, waiting a few minutes, and all seems to be well again - sometimes for only a minute, sometimes for several days. No steam leaking, the water in the reservoir seems to be normal temperature, the radiator is not overly hot, and the AC keeps on blowing ice cold. Me thinks it is not really overheating, it just thinks it is. So where to start? Change the temp sensor first, or the thermostat? It seems the hoses are fairly firm, I don't believe they are collapsing from suction.

2004 Mazda6 V6 auto with 220,000 miles on it. Yesterday, in rush hour traffic on the highway, saw a puff of white smoke from under the hood. Tried to get over to the right- by the time I got over, I'd passed the last exist before the Baltimore Harbor Tunnel.so had to keep driving till I could find a safe spot to pull over.
Temperature gauge spiked, so I turned on the heat, on full- and got cold air coming out. Temp gauge then dropped to cold, and all dashboard warning lights lit up. Small antifreeze puddle under car.....had it towed home. Truck driver was able to get it started long enough to roll it off the truck into parking area.
How badly I damaged engine by continuing to drive the 2 miles through tunnel?

I have a 95 ford f350 when u run it with the heat on the truck temp gauge says its overheating the heat will go from nice and hot to ice cold as soon as the temp gauge goes up to the red. I replaced the thermostat also checked for coolant leak cant find any but truck has strong anti freeze smell and the radiator keeps going low on coolant.

I have an 06 F350 6.0 and I am having long cold starts. On the gauge the ipr is maxing out at 85%. This only happens when cold and have never had a no start issue. When hot the engine cranks right up and the ipr stays in normal range. FICM has been replaced. Does this sound like needing a new ipr only?

I have an 03 f250 6.0 150k milage and lately my A/C has not been working at its best. Its intermittent, and for some reason it will work fine until i get on the highway and it just blows hot air. Would this be a leak or clutch issue? One thing I have noticed if my oil/coolant is above 200 the A/C will blow hot air but not return to cold when the temperatures return to normal. I haven't done any trouble shooting so my first thing ill check are the fuses. As far as the compressor goes its an alien object to me I have never had A/C issues with any vehicle i have owned.

Was driving my truck I have a 97 f150 4x4 4.6L, btw. The heater started blowing cold air and I looked at the temp gauge but it was showing lower than it normally does and then, after a couple of miles or so I looked at the temp gauge again. By this time I was in my driveway. And it was overheating it might have been that way before I looked at the temp gauge again. But any way I opened the hood didn't see any leaks, all my hoses were hot except the top heater hose. Also checked the oil it was full and coolant was too, what this could be? Sounds like a t-stat to me? But could be worse. Also forgot to mention that the oil had no signs of water in there nor the expansion tank cap !

My CC display shows all icons on the right regardless of settings (see pic). The temperature setting and outside temp will not come on.
The second issue is that my front blower starts to lose velocity and sounds strange on long road trips.

Just about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?
