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...
View 9 RepliesI 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.
So, I have a 2003 Passat Wagon GLS with a 1.8T and 110600 miles on it...
Here is my dilemma... I try and change my oil every 4.5 to 5 months and the passat has been running like a champ, but recently noticed the car was beginning to sound like a diesel engine and we were starting to go through the coolant..
Throughout this entire time my gas mileage seemed to have improved and I never noticed any oil or antifreeze/coolant leaking underneath, and it wasn't until recent that we noticed a loss in power.
My wife had checked the oil and noticed a yellowish/rust-like junk on the dipstick, as well as the dipstick not registering any oil... We also noticed the turbo was whistling during hill climbs.
We still have about two months until a required oil change is needed, but when it comes to mileage we surpassed it.
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.....
View 14 RepliesI have a 2000 F250 superduty crew cab short box. It has any occasional issue of either just shutting down (engine dies) which seems to happen if i hit an occasional bump. The other issue has happened a couple of times which is it will lose power and just go to a rough idle. I shut it off and restart it and it will run fine. I'm wondering if it is the throttle position sensor.
View 2 RepliesLoss 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.
View 3 RepliesI've had this 01 7.3 for a few months now. When I first purchased I dropped new battery's, couple glow plugs, and wire harness going to the Pass side valve cover. it has 150k on it and an Edge tunner.
My first problem was about 2 weeks ago, it was raining and i was making a turn at about 5mph And all power shut off. I put it into park cranked 3times started up and the tuner stayed off for about 3minutes. I ran to auto zone and picked up a cps (I've recently found that oem is the only way to go?)
I made a trip about 2hrs locked the CC in about 70mph and the boost was going well over 12psi. this seems crazy because i usually dont get it over 4psi. I drive it with a light foot. on my way home i was pulling a trailer about 8000lbs load driving about 5mph out of the lot it shut off again. Started right back up and made the trip home fine. With the exception of the erratic boost.
Yesterday it shut off at about 40mph and turned back on its own. I am not throwing out a lot smoke doesn't have problems starting, I did a once over on the wire harness's and nothings jumping out to me.
I am losing a small amount of antifreeze, about a cup every thousand miles, so I have to consistently add antifreeze. When i remove the oil fill cap, I have a small orange ring leading me to assume the loss is into the engine.
Dealer pressure tested system and told me everything was good, could not find a problem, which I think is likely not correct. How to proceed?
replaced heater core because when pulling a trailer it would admit steam out the defrost vents and the smell of antifreeze, what it could be?

Wicked wheel, 6637 filter, DP tuner, Summit 5" exhaust, pressure regulator somewhere in the boost circuit to fool the computer a bit....
Every few times I drive the truck it will stumble and maybe even stall. The issue feels something like a CPS problem, although I've swapped out a few CPS to see if I by chance had a bad one in the engine as well as a bad one in the glove box. No changes. I was driving home from work one afternoon and it was running particularly bad. I stopped off at a local garage (who doesn't work on diesels and was reluctant to plug in....but did because he's a nice guy).
He plugged in with his snap-on tool and came up with P0603 and P1211. The P0603 seems to be nearly inevitable with a tuner. Check P1211 sounds like it could be an issue with a number of things, but I tried to attack the free and cheap issues first. I dropped my tank and had a look inside. I was hoping to find a squirrel wrapped around the sending unit, but there was a disappointingly small amount of crud. I cleaned it up and put it back in, then changed my fuel filter. No improvements.
So I decided to get with the program and buy AutoEnginuity. Got it. Even did some reading in class and did the initial homework assignment on page 2 or 3. Seems like the best thing to do it hook up, set up some parameters to monitor, and drive around recording until the problem happens. But.........what parameters do I want to monitor? I don't want to overtax the OBDII bus with too many requests such that my data looks like crap.
A few other things............ In the last year I swapped out the valve-cover gaskets & harnesses with an all-in-one molded setup. About a month back I replaced the exhaust back pressure sensor and tube.
Had my oil changed on my 2011 F350, and the tech said that I lost one gallon of antifreeze coolant. Where could the coolant have gone? We could not find a radiator or hose leak. I am afraid that the coolant somehow got into the engine oil, and may have damaged the engine. I have 46000 miles on the truck.

Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.
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?
2003 Ford E 350 7.3L Trouble - YouTube....
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.
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?
View 14 RepliesI 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%.
I have a F350 that has intermittent power loss.
View 14 RepliesFor 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....
View 4 Replies1999 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 ?
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?
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?
