I have the Banks PDA and Six-Gun with the pyrometer and Banks CAC on a 2006 CC DRW 4.10's lifted 4 inches with 33muds. I pulled our 24 boat up the Altamont pass near Tracy Ca. It is a pretty good run, maybe 10+ minutes of grade. I had the PDA in level 4 going about 75 mph. The EGT's were about 1200, engine temp about 210, but the engine oil temp alarmed at 225's. I wasn't even coming close to full throttle...maybe 1/2 to 3/4 and all other parameters were right in check.. Just cruising on the Freeway, empty, the oil temp is 200 -205. Anyone have any input on oil temp limits?

 

Now my truck ran hot, I think the clutch fan might be going bad, I get a high pitched squeel while under load and the water temp got to the hot zone. I shut off the air, coasted in neutral used high idle and the temp went right back to normal. the rest of the trip went fine w/o the A/C on. I took it in to be looked at today.

 

Let us know what they find. Sounds to me that trucks overheating is very far a few between. Most pull great and don't even move the temp needle. Thanks guys.

 

I have an overheating issue and it's been bugging me for some time now. I tow quite often and it only shows up when I am towing. I had the truck now for almost a year (2004 F350 6.0L) with no problems about the 3/4 I have had it. No overheating issues. Now when I'm pulling a load, the truck starts to overheat. I am not going up any hills or any kind of steep grade. This is a hwy going max 120km/h. I overheated three times travelling about 200km. I had to pull over and lower my speed untill the temp went back to normal range. Also, it's slow when comming off the on ramp onto the hwy. Feel like im driving an old beater. Exceleration sucks and I can't get over 120km/h. I took it in to get looked at and they said that it was warped heads. Possibly blown headgasket. NO mods, or chips installed. Completely stock.

 

The dealership told me the noise problem was a small tear in the charge air hose ( blue hose going into the intercooler). They also told me this could raise the temp due to higher EGR temps.
I will find out this saturday if that fixed it.

 

I'm having over heating issues. Fan motor died at 31,000 miles. it got in the hot zone three times. Now I'm worried about having a head gasket problem. Also turbo over boost problem for the third time. Stock truck used for towing (7,000 lbs max) and vacations. Seem like everytime I use the truck for what it should be desgined for (towing loads) it experiences problems. near the end of the warrenty, so it's time for Ford to extend the warrenty or they will own the truck. 04 f-250 4x4 super cab

 

I live in Tucson, AZ and I have had problems with my truck overheating every time I hitch up my 11K 5th wheel and head for the mountains. The guage will start climbing up to the "H" almost into the red and the clutch fan kicks in and she starts cooling down to midway- sometimes it will stay just below the h for awhile. The clutch fan at times will seem to resonate or pulsate. What I mean is you will hear the fan roar and go away and then roar and go away.

I had the truck into the dealer 11-2005 (15,971 miles)for this problem and they found that oil cooler had a restriction-turns out "casting sand" from the foundry where the blocks are produced does not get thoroughly cleaned out of these blocks-wtf?! So they replaced the oil cooler, EGR cooler (said it had an internal EGR leak), radiator, de-gas bottle, and a couple of differnt sensors they had to upgrade. It also had puked coolant out of the degas bottle.

Just got back from up north (pulling my 11K 5th wheel) in the White Mountains thru Salt River Canyon, and had several times that the guage would come up to the H , fan would kick in, and it would cool back down. It would do this pulling 7% grades or on flat ground). Outside temps would range from 80 to 103, it didn't seem to make any difference. I was coming down I-10 almost home, pulling a grade at Texas Canyon, and all of a sudden the temp shot up and bells went off (alarm) and on info screen it said "CHECK ENGINE TEMPERATURE" and the guage was in the red. I thru it into "N" and was doing about 70 to let it cool down- outside temp was 92. I was able to get it to cool down and continued another 30 miles or so home. I checked under the hood and more of the coolant had spewed all over the degas bottle and hood.

The truck currently has 25,000 miles.

I tested this programmed in "tow" setting and stock setting - I have a Diablo Predator. It didn't make any difference.

So, I took the POS into the Fords dealership yesterday and we'll see what happens.

Wish I had my old 99 SDTY 7.3 ! But, I do love the tow/haul setting on this tranny!

 

two weeks ago i towed the trailer to the grand canyon and back. the truck never even got hot. outside temp was as high as 116. the clutch fan now comes on before the temp gage even moves from middle position. i think that the reflash the dealer did on my truck a couple of months ago mad a difference. the fan used to come on only when the truck got hot. truck runs great now.

 

I got mine back from the dealer for the heat problem, they replaced the belt, tensioner and the thermostat. After towing this weekend I still have the heat problem, but it only gets hot in one portion of the drive ( 40 miles thru though mohave desert going uphill to searchlight. ) After I top the hill in searchlight the needle never moves from the normal position.

 

I pull an 9000lb 5er over the grapevine when its 90-105 degrees. No problems yet, no lost coolant. Needle starts to creep up, fan kicks in and needle drops right down. I don't push it, stay between 60-65mph on the flat, hold it at 50-55 on the hills. I have 23k on the truck now........

 

I have 2500 miles on my 6.0 now. At 1200 miles I attempted to tow my 6k toy hauler on its first trip from Ramona to Ocotillo Wells (San Diego area) and did not make it. The trip includes some twisty climbs and respectable grades. Prior to this trip I had never seen the temp needles move from their usual position or heard the fan. On the first climb the fan came on briefly. Seemed kind of loud to me. Second grade saw the needles take off like rockets and hit the red as I crested the top. It quickly cooled to normal as I started downhill. No fan this time. About 10 miles later after cresting a hill, the temp needles took off to the red again, fan made a mighty 'this ain't right' roar and the thing shut down. All in about 30 sec or so. Outside temps were in the mid 80's. Ended up being the fan clutch.

Two successful tows out there since. Fan gently whirs in the background when needed and temp needles do not move. One trip in the 80's. The second trip about 105 on the uphill return. Seems to be working well now.

Just noticed tonight that my coolant is very dark and has a sheen on top. Not sure what to make of that.

 

I pull a 8k lb toyhauler 8-10 times a year. From 40-60k, no problems, then I got the fan roar and the spiked temp. This started at 70k. Now I'm at 99k, it's been in 3 different dealerships for overheating and they have all done the systematic band-aiding; new cap, lower degas fluid level, changed thermostat, flushed cooling system, everytime it did nothing, but I've spent over $500 between the deductable and other costs and nothing's changed. Now, at 99k, I'm taking it in on tuesday w/ my toyhauler and me and the tech are riding around until it does the usual which is (as described several times in this thread) the fan roars so loudly you have to yell to speak, the engine temp steadily rises and not even turning the heat on slows it down, the needle spikes and after about the 3rd time that it does that, I'll lose power until I am either running downhill or I just pull over to quit. If I'm not towing, it never does it, but EVERYTIME I tow my toyhauler I spend the entire trip staring at the gauge waiting and listening for the roar and my next overheat.......and all of this out of a $50k+ 3/4 ton that is supposed to be the most powerful, most fuel efficient truck ever made. What makes it worse is all of the info that's out about this and every tech, service manager, and general manager acts like he has no idea what I'm talking about!!!

 

Reply to SDSD.
a guy at my work also has an 05 6.0 f-250. he had oil in his coolant and it was the oil cooler leaking into the cooling system. this is a common problem. dealer had his truck for a week+. good luck.

 

On Saturday, I pulled an <AHREF= href="https://www.ford-trucks.com/user_gallery/displayimage.php?&photoid=115601&width=0>oversize" <a <AHREF='target=\"_blank\"'>oversize 14k load for 130 miles in 96 degree temps at high elevation (2 mountain passes) and the 6.0 performed perfectly...

 

Awesome. I love to hear it. I recently moved from my little apartment to a house so I borrowed a 25 ft car hauler to haul all my stuff. While this was not heavy by any means I did enjoy pulling it. Normally I only get to pull about once a year when I drive back home to Idaho for elk season. When I was done moving I pulled a 1959 Chevy Apache on the same trailer about 100 miles to trade it for a 56 Hudson. It was about 90 outside I believe and pulled a few hills at the cruise never came off of 65. My buddy made the comment about never saying a bad word about my truck. With the truck and trailer I figure around 6000# or so. On my Banks PDA I noticed temps in some areas of the trip (not going down hill) actually going down.

I will post pics of the classic truck on the trailer in my gallery.
