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...
View 8 RepliesI have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.
View 8 RepliesI was wondering what is the normal range of trans temp in this truck? I was driving home last night and after a couple burst of wot , getting on the freeway, I checked the info display and it showed 200 degrees for Trans fluid. Truck was unloaded with 80 degree Temps.Also I guess how accurate is the dash Guage? does this seem like higher than normal Temps? 15 f350 cc sb 11 k miles ,gas motor. i aslo drove another couple miles coasting around and the temp never dropped past 196 .
View 4 RepliesSo beating the dead horse here. I have an 03 6.0 that the batt light comes on only after reaching operating temp. Using fords self test mode it shows 13.5V to 14.3V, pull the regulator plug light goes out, A circuit has batt V and I circuit has no V Key off and batt V with key on. I have wiggled wires in the dash and under the hood replaced the reg plug. I feel as though I have read every thread with not much success.

View 10 RepliesAt idle temperature is above middle. Upper radiator hose, which is connected to the thermostat is hot. Lower radiator hose that feeds back to the engine is cold. Radiator fan will not stop running if the temp guage is at middle to needle above middle. When running the temperature reading is normal at 30 mi/hr (middle to just below middle). Temperature will also go down if at high rpm idle, about 2,500 RPM.
New thermostat replaced last week. Water pump replaced less than one year ago. Upper radiator and lower radiator hoses are pressurized when running and off.
I suspect the thermostat was installed incorrectly. Pressurized hoses mean excess air in the cooling circuit/system. If so, does it mean I have to bleed out the air? How do you bleed out the air on a cooling circuit of a car, I thought the reservoir tank already does that naturally? I think the normal range for the temp guage should be 1/3 of the whole range of the guage, right?
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?
View 14 RepliesI 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???
View 4 RepliesMy 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.
View 8 RepliesI 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?
View 3 RepliesI 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.
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?
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?
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.
View 1 RepliesI 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.
View 6 RepliesMy 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.
View 14 RepliesThe 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.
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.
I don't have my manual handy, wondering what the normal operating temp of the coolant is for a 1.8T B5? I believe it is 190, but want confirmation.
View 1 RepliesWhen I fire her up, the AC will blow cold for 10ish minutes until everything is up to normal operating temperature. Then it tends to blow warm, and that last for about 20 minutes, before finally settling back down and being cold AC again. I initially thought it was an issue with my compressor disengaging, but it doesn't seem to be...
