Ford 6.0L Power Stroke Diesel :: 2003 - Loss Of Coolant When Pulled Heavy Load
Jul 1, 2015
Loss of coolant! I have a 2003 6.0 diesel with 200,000 miles. I put in a new oil cooler and ipr egr delete two years ago also flush the system and added a coolant filter. I filed it back up with the red antifreeze. Now the problem I have never lost any coolant since then and my deltas are about 5 degrees. But the other day I pulled a heavy load the first one since I did the repairs (coolant got up to 220 degrees and would drop back down) when I got home the coolant tank was about a inch low. I let the truck sit about 3 hours and checked it again and it was back at the full mark. Drove it the next day and it's back low about a inch, Any clue what's going on.

I have a 2003 f 350 6.0, when under a heavy laod such as towing a 3000-pound trailer up a long hill at approx 60mph and 2000 rpm it intermittently mis fires.The boost gauge bounces up and down and i here a poping sound from the engine compartment.I have had it to several dealer and independent shops but with out the trailer or a heavy load it runs perfectly.They have told me fuel pressure is good and changed all fuel filters with OEM parts.

I posted earlier about a whistle that appeared when I was towing my old travel trailer (6000 pounds). It only happened a couple of times, and I had a hard time replicating it, so I elected not to waste any money with the deductable, and possible additional costs for a non-covered issue at the stealership.
Now, I am towing a larger 5th wheel trailer (11000 pounds), and am experiencing this whistle on every steep grade, while towing. Below are a couple of things I noticed, that had to be, before I would get the whistle:
* It only seems to happen while the cooling fan is engaged, and also only when the rpms reached 2800 and above.
*If the fan was on, but the rpms were turning below 2800 rpms, then it would not whistle. It would, however, after the transmission downshifts, bringing the rpms back up, while climbing.
*If the engine was spinning at 2800 rpms, and the engine fan was not engaged, then it would not whistle, until the fan would kick in.
* It only seems to occur when I am climbing a steep grade, on a warm day. Although, I haven't experimented on steep grades on a cold day...
It sounds to me like there is an issue with the engine fan system, but I thought I would put it out there, just in case any of the diesel guru's out there might know of something else that would cause a whistle like this, i.e., turbo?
Oh by the way, I also think that I have a performance reduction lately. However, I can't know for sure, as I have never towed this much weight with my truck before. I just kind of expected that I would be able to pull to the top of these grades, with a little extra peddle to spare. I have to floor it, just to "try" and keep up with traffic. And I haven't calculated my fuel mileage while towing this beast yet, but WOW, that fuel gauge needle sure does drop like a rock!

So I have a 2003 6.0 king ranch w/ 164k on it.. EGR delete, high pressure oil pump, coolant filter and SCT tuning. A couple months back I had a coolant flush done. After about a week the coolant tank was empty.. Engine heated up due to loss of coolant.. I flushed system again and put ford gold coolant back into the tank. (5 gallons). A couple days later and coolant was very low and engine heated up?? There are no signs of leaks anywhere...Added water and it cooled back down. I'm lost. EGR is deleted but no studs done.....

I have a 1991 300 6 with an e40d trannsmission, our 4610 Ford tractor broke down in the field so i pulled it maybe 50 yds with my truck, it didnt like it but it did it. Now my tranny is dripping at a decent pace it looks like from the hole in the bottom of the trans, drove it ten miles home and it shifts fine. What could i have done??

2003 f350 6.0 diesel, driving on the freeway at 70 mph, all instrumentation went off, the radio went off, the engine was still running fine. While pulling off on the off ramp, when the speed was about 20 mph the rear end jumped up as if the transmission was trying to go into reverse. After traveling about 4 miles at about 15 mph the rear end jumped up about 6 inches and the drive shaft pulled out of the spline and drove itself into the pavement. Why this happened. I have put two new batteries and an alternator in the truck and it has been fine every since, but I am still concerned it may happen again. The truck has a 6 inch lift on it.

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

I recently had an upper radiator hose bust and ever since I have been having a slight water leak. It appeared to be coming from between the layers of rubber on the new hose which I replaced twice since the incident. Both hoses had water seeping from the same location. This afternoon I plan on doing a pressure test on the cooling system to diagnose where the water may be coming from.
My question is could a loss of pressure cause larger than normal Oil and Water deltas? If I have to replace the radiator is there a particular manufacturer or type I should avoid? Should I try to get a factory replacement from Ford or would an Autoparts unit be sufficient? The original is still in the truck now with 286,000 miles on it.

Recently I had a radiator hose split while traveling. The EOT got up to 250 degrees before I could pull over and stop the truck. I flushed the cooling system with water, replaced the thermostat, and added Ford Gold coolant as per the recommendations in the Tech folder. My oil temps are higher now than prior to this incident. Unloaded on a flat road my deltas are about 10 to 12 degrees @ 60 mph.
My water temp will stay around 190 to 195 degrees while my EOT have reached 212-215. I pulled a small utility trailer and saw a delta of 17 degrees this was at about 75 mph. Typically unloaded I would only see a delta of about 8 degrees and this was at 80mph. My question is do you think a EOT of 250 would burn the oil, I had Shell Rotella T5 5W40 in the engine. Would it be possible that the oil cooler is partially plugged from this temp?

My friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.

I am trying to figure out the problem with my 2002 ford 7.3 Engine.
[URL] ....
It has a lost of engine coolant. The oil is 100% clean with no signs of Coolant. No chocolate milk effect. Also it makes a Odd thumping noise at idle. I think it is coming from the Exhaust Manifold.

2002 7.3, losing coolant. Occasional whiff of antifreeze, not in oil. I use my truck to tow a food trailer that's only about 4500lbs, some highway, most city driving. 173K clicks, bout Jan 2016 with 130K, first time this has happened...

Went to do my first oil change last night. Removed the horribly over tightened oil filter with out issue. We to pull the drain plug out of the oil pan and could not get to budge. Got a bigger breaker bar and got it out. Plug came out with about half the threads of the pan stuck in the bolt threads. Bolt must have been tongued to 100+ foot pounds. Got a new oil pan on order with dealer think i will have to cover cost since i was doing my own oil change.
Truck is a 2016 f250 6.7L.....

Coolant temps getting much higher than oil temps under load. Is there any problem that could cause this other than a bad temperature sensor? Reading temps with an Edge CTS 2 monitor. Think I'm going to hook up a mechanical gauge in the morning and see what it shows.

I have an 03 6.0 Power stroke. My problem all started the other day when I started to occasionally not get any boost on acceleration and lose of power and a lot of vibration like it's about to cut out but it got worse now today I drove it about 5 miles into town when I got to town I noticed a rough idle I got gas in a gas can not in the truck. I got back in to leave and I had absolutely no power at all the truck stalled out and it was very hard to start finally got it started and it runs really rough almost like it's going to shut off.
So when I started driving I would only make it about a mile or so with out it chocking out and having to let it site for a minute or two and start it back up and go another mile or 2 and have it do the same thing all the way home all the time I have vary little boost if any at all except for when I first pull out now oil pressure is good and engine never over heated some of the codes I have is an EGR code and a contribution balance code for several cylinders I was thinking possibly a maf sensor or a clogged egr not working right.

So I replaced ball joints and hub bearings on driver side of the truck today ( passenger side tomorrow). Problem is when I pulled the axle out gear oil started to leak from axle housing not a lot but a leak nonetheless. Is this normal or did I break something.

Did my first oil change with Rotella T6. I drained, replaced filter, filled with 13 quarts new. Started engine, let it idle about a minute, turned off, checked level and everything was good. Then I drove about 3 or 4 miles just to make sure everything sounded ok, and when I got back home checked level one more time. After driving, the oil level was still fine, no leaks detected anywhere, but there was smoke coming out of the dipstick hole when I pulled the dipstick. Is this normal?

Coolant flow seems to be not at its max output seems like it's blocked somewhere. Lots of pressure in bypass line of radiator after clamping of hose and releasing pressure of degas bottle?

If there is indeed diesel fuel in my coolant, what is the most common cause of this problem? Truck has low power when towing 8 tons.
I've replaced water pump due to truck overheating and blowing off radiator cap during first hard tow up steep hill.
Replaced all radiator/heater/coolant hoses.
Replaced radiator.
I've also flushed the cooling system 5+ times now with coolant flush and distilled water. Each time, less and less evidence of brown-colored stop leak.
The stop leak looked like diarrhea, slightly chunky. After the third flush, stop leak in coolant lessened.
HOWEVER -- 4th/5th flush of coolant each still looked like brown milk. Coolant has a strange chemical smell, possibly diesel fuel.

I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

I noticed about 1 year ago I had diesel in my coolant but wasn't sure.. took it to a Ford Guy about 45 minute's away.. He seems to know his stuff but when he tested the coolant the results said less than 2% diesel.. But he did find an injector issue and swapped it out..
Forward to present.. there is diesel in my coolant now , since the level is rising to almost overflow and I believe this has been doing on for quite some time as I have that smell you get in the cab..
BTW - All injector cups have been done about 3 Years ago.. On another note , I get white smoke on start up especially if the truck has sat for a day or 2.. What can cause diesel in the coolant.. I did a complete coolant flush this summer and was super **** about getting all the old coolant and gunk out.. Ended up with only clear water coming out the degas
