Ford 6.0L Power Stroke Diesel :: 2003 - Engine Heated Up Due To Loss Of Coolant
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.....

Had coolant in oil, so pulled motor. Got used motor to replace it with, thinking about doing some work on it before reinstall.
Got bellowed up pipes, injector o-rings, front and rear main seal, and will use best parts from both motors to make one. I'll also shim injector armatures back to spec.
Should I do injector cups too? What else is recommended to do at this time? Both motors are 350k or so, I was on a budget at a moment and have to make it work with what I got.
Ford 7.3L Power Stroke (1999-2003) :: Turbo Boost Loss And Engine Starting After 2 Attempts
I've got a 2002 Excursion which has been giving me a little trouble lately. I've got a DP tuner, 4" exhaust, afe stage 2, and gauges (boost, trans temp, EGT). I've been running these for about a year now without any truck problems until recently
So I noticed over the past couple weeks it has gradually been taking longer for the engine to start. Started off by just having to turn the engine over a few more times. Now it has turned into having to turning over the engine for a few seconds, then turning it to off, then trying again. It always starts on the second attempt to start my truck and sometimes really hard where it blows out a little black smoke.
Not sure if this is a correlation to the problem above or not, but I've also been losing boost pressure, and I'm not sure when this started since I haven't been on the highway for a while. I noticed this because this weekend I drove on the highway and saw that I was blowing some black smoke every time I accelerated which has never been the case.
So I check my boost gauge and see that I'm sitting at like 3-5psi when I used to be at around 10psi+. I also noticed when I accelerated the boost pressure would increase like normal but then quickly drop once I stopped accelerating which is unlike anything I've seen before in my truck. I don't seem to notice a huge difference power or throttle response, but then again 95% of the time I'm driving under 40 mph to get to work. So this problem could have started the same time as the starting problem, but I can't say definitively.
What this problem could be, what to check or test?
Ford 6.0L Power Stroke Diesel :: 2003 - Loss Of Coolant When Pulled Heavy Load
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.

Just got my truck back (450) from rebuild on tranny. Hooked up my new obd link mx , and was out running the truck for a while. Started running it pretty hard to see what the gauges would do. Noticed the engine coolant was getting up pretty high, usually around 240-250, and then hit 270!!! My temp gauge on the truck wasn't budging , just stayed between hot and cold. Is this normal?? Seemed pretty hot to me but if i just took it easy on the throttle it would average around 230. If i stop and idle it quickly goes down to 206. Look at oil temp and tranny temp also engine coolant temp is bottom middle.
View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Engine Coolant Temp Sensor Locations?
I was going to order a ECT gauge and was wondering where to mount the sensor. I have already used the port under the T-stat for the coolant filter. The gauge sensor is a 1/8 NPT. Would the block drains be a good location, or is there another location that will work.
I know the coolant filter housing has a port, but I would prefer the sensor be on the motor.
Ford 7.3L Power Stroke (1999-2003) :: E350 - Sudden Power Loss / Zero Power
I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

Ford 7.3L Power Stroke (1999-2003) :: Loss Of Power / Rough Running
I have a 2001 ford 7.3l powerstroke diesel. When I first noticed the problem I was towing a trailer going up a grade and got into the throttle almost to the floor and noticed a loss of power and the service engine soon light flashing extremely rapidly a few times and never came back on. I made it home, still lacking power but not running rough. I drove the truck to work the next day and the truck was running rougher and loosing power. It ran great through lower RPM's but seemed to trip as soon as you gave it over half throttle. eventually the truck wouldn't run right at all and lacked complete power. It idled rough as well. My mechanic threw the computer on it and it said injector pressure reading too high or too low.
I was told to replace the IPR on the HPOP and I did. (I also replaced the fuel filter and changed the oil). After replacing the IPR it ran great, had full power! then it began to slowly die like it did before until it sounded like it was running off 4 cylinders again. I pulled the ipr out, cleaned it and changed the oil again. It seemed to clear it up for an hour and ran great but then began ran rough again. I also replaced the CPS sensor. I feel like its not getting enough fuel or something, im just wondering if it could be the ICP or the lift pump. There is no check engine light at all. Its just got me stumped because cleaning the IPR clears everything up.... temporarily.
Ford 7.3L Power Stroke (1999-2003) :: Power Loss Throwing P0472?
I just recently bought a 199 E350 4x4. I changed the injectors and it drove a little bit better but was still lacking power and was throwing a p0472(exhaust back pressure code) and a p0113(IAT sensor circuit hight output) code. Last night i put a new ebp sensor and the truck came back to life for about a half mile or so then went right back to the way it was. I took the sensor back off and cleaned it in case it some how got clogged from my short ride. It surprisingly did have some soot in it which i cleaned out. Also blew air into the ebps line while still mounted. Put everything back and still nothing. What could it be? Could i possibly got a bad ebps?

I am going along and the power just goes away. Sometimes it is a 50% loss other times it is an 80% loss. I hooked up my scanner and found an IPR code. I replaced the IPR and connector, nothing changed.
As the scanner info shows the Duty Cycle and Pressure track about identically until something goes wonky. When I loose about 50% power the pressure will not get above about 1500 psi but the duty cycle will run up to 60%. Other times when I have a bout an 80% loss the pressure and duty cycle both track low, no more than 1200psi and about 20%.

For some stupid reason, my truck decided to lose power today when exiting the freeway. D/s egt gauge verified it with no increase in temp when stepping on go pedal. After about a minute, I could feel it gain power. So, rolled into fuel station, and topped off tank. While filling, I popped the hood and started messing with the uvch and looking around. It was then I noticed that darn hose riding on top of a ton of wires. Pulled said hose up and sure enough, a wire is shafed clean off of insulation. Anyway, something to check while looking around under there....

1999 f250, 280,000 miles. I use Power Service with every tank, oil changes every 3500. Had a few of the injectors changed several years ago after getting bad fuel. Tranny "built" when rebuilt, about 60,000 miles ago.
Truck starts and drives every time, no miss or rough idle, no smoke. Just not as much power. It downshifts sooner and really seems to resent towing my atv trailer. Where do I start ?
Ford 7.3L Power Stroke (1999-2003) :: 2007 - Acceleration And Power Loss?
I own a 2000 7.3 6 speed with 175,000 miles. I just bought it less than a month ago and it is my first diesel.
About a week ago I stepped on the gas and it just had nothing. I have a TS 6 position chip that I unplugged as soon as I noticed the loss in power. When I first bought the truck it was incredibly fast and now it has nothing to it at all. I have to have it higher in the RPM's to go up hills (especially when its not warmed up). If I push the pedal down it will sound the same, boost will get to about 14 (without chip) and the truck doesn't let out any smoke but it just doesnt have any power at all. I recently towed another vehicle on a trailer and it really struggled with it, more than I thought a diesel should.
When the chip was in, the truck would let out black smoke even after I noticed the loss in power. That made me think that the engine was getting enough fuel. I thought there could be a boost leak somewhere but it still builds 14 psi. However, I do not feel boost kick in at all! When I first got the truck it would only build around 14-15 stock but it felt a hell of a lot faster and I could feel when boost would really kick in. I took off my intake and looked at the turbo and the fins are in great shape and there is little to no play.
What the problem could be? I don't have very much money to start dumping parts into the truck and Im not sure what to do. I guess my questions would be:
1) Is it a boost leak, fuel problem, or something else?
2) Could a gelled filter give me these problems?
3) What should I do and where should I start?
Ford 7.3L Power Stroke (1999-2003) :: 1 - 2 Second Power Loss While Driving
I have been getting about a 1-2 second power loss while driving. happened last friday when at a stop light, pressed the pedal and started to go then it dropped out for a second or two and then caught right back up. only cut out twice in 10 minutes then ran fine for another week. This friday oddly enough , it happened again while driving down the road. happened about 5 different times in 10 minutes, then back to normal. I replaced the passenger uvch with dorman, but not driver side a couple of months ago . Does this sound like the other uvch, or tps?

2002 7.3L SD ... He told me when he was taking his son to school he turned on the heater. When he did this he could feel the truck lose power, he turned the heater off and it drove fine. Turned it back on and power loss happened again. I haven't driven it to test yet or see what is happening but I also don't understand how this can happen. The heater did get warm, and he does not have to add coolant to the system.
View 13 RepliesFord 7.3L Power Stroke (1999-2003) :: Loss Of Power During Acceleration
A little background first on my 1999 Ford F350 7.3. A few months ago I noticed i had fuel in my coolant which lead me to a cracked injector cup. I replaced all 8 cups and since I had it apart, and I bought the truck used and didn't know what had been serviced, I replaced the injector o-rings, glow plugs, valve cover gaskets, and valve cover gasket wiring harnesses. Got it all back together and had been running great.
About a week ago I was parked with engine running and the stereo suddenly turned off. A few minutes later I turned the truck off and turned it back on about 10 minutes later and it wouldn't start. Batteries appeared dead so I jumped it and made it home. Took both batteries down to AutoZone and since they were under warranty got two new ones. Figured out my alternator was bad and not charging my batteries so I ordered a new one.
Up to this point truck has been running fine. Truck had sat in my driveway for the week while waiting for the alternator. While I was out of town my father in law went to use the truck and noticed it wouldn't start. He hooked some jumper cables up and got the truck started. He said as he drove off the truck had no power and smoke was pouring out the exhaust.
I charged the batteries and installed the new alternator. Truck starts great and seems to be idling normal. When I took it for a test drive it has no power when accelerating and black smoke pours out the exhaust. The truck will barely make it up any type of incline.
I thought maybe it was the injectors not firing. Wiring harnesses are plugged in and do not appear to be damaged. I did not remove the valve covers yet as it's not difficult but time consuming and I figured since I just replaced all of it that it should be ok. I did a buzz test and all injectors passed. I get no trouble codes or check engine light.
