  1. check engine light?

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Likely an Overboost indication, will clear on its own. Typically happens at WOT with a tune that allows boost to exceed the stock 18-20 PSI. I believe over 25 PSI the indicator lights, but that is memory from a few years back running a tune and towing hard. Good Luck Coolhand
  2. Truck shuts off while driving

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Hi, Several thoughts for you; 1. Check the battery connections, both Batt + and gnd, ensure they are tight and not corroded, including the ground to the frame. 2. Check the fuse boxes and relays to ensure proper seating, removing and replacing all can ensure good connections. 3. Check the 42 pin...
  3. greasing upper ball joints

    99 & up Upgrades and Aftermarket - 7.3L Engine
    All, I have Moog Greasable joints with the shorty straight zerks. I was asking myself the same question Saturday while greasing the front end and replacing the steering stabilzer that had leaked and was useless. Thanks for the tip. I was at TSC Sunday and forgot to look. Coolhand
  4. 7.3 with 300k miles overheated, shop says scrap it

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Tough break! I would run a compression check 1st. That way you can decide to pull the motor, or a do an in truck repair. I too would pull the heads and check for warpage, you would want to check the block deck warpage as well. Not likely it is warped, but possible - to get the block deck...
  5. Please read. Need help with starting issue ASAP

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Hi, Given the area you are working in with the clutch, it may be a chaffed wire on the bottom of the 42 wire square connector that goes across the drivers valve cover. Easy to remove. Take the brightest light you have and carefully inspect the wires that may have contacted the valve cover. If...
  6. Looking to buy 2012

    6.7L Power Stroke Engine and Drivetrain
    I've been watching with interest the 6.7's. I currently have an 01 7.3 with 150K, still runs good, but wondering if time to switch up. I had an 06 6.0, loved the truck, didn't like being left with a bad turbo at 1400 miles. But that is the past. I have run Dodge's as well, my son has an 06...
  7. Mechanic says he's never seen anything like this

    99 & up 7.3L Power Stroke Engine & Drivetrain
    FWIW, I replaced the ESOF hubs with Warn manual hubs on my 2001. Fine with me to switch them in when I need them. As KLHansen said, leave em locked if you think you might need 4WD. Dodge trucks are always locked, as they do not have hub disconnects. Sure a bit more wear and slight fuel economy...
  8. will turn over but not crank

    Glad you fixed it!! Coolhand
  9. will turn over but not crank

    99 & up 7.3L Power Stroke Engine & Drivetrain
    At 45 degrees could be the GPR - glow plug relay. Use search on this forum for more info, top side motor, looks like starter relay, when WTS lite is on [an up to 2 minutes afterward] this relay should be energized. 2 large lugs, one has direct connect to batt the other to a yellow wire. Use your...

    Go For It. keep us posted on how you are doing. Once you get done, you'll have a truck that you can drive a long time... Coolhand
  11. New steering gear but still wanders

    99 & up 7.3L Power Stroke Engine & Drivetrain
    The unfortunate truth is these solid axle leaf spring trucks wander. I have had 3 of them 99,01,02 and each one did the same, I have several friends who have had these as well. It is inherent in the design. Of course having all the front end components correct, and shocks fairly new and...
  12. Trickle battery charger w/ dual batteries

    99 & up 7.3L Power Stroke Engine & Drivetrain
    nickt916 Search is your friend, there is a wealth of info on this forum about batteries, charging, charge rates etc. Have a look... Net net - what the other guys have said is correct, batteries in parallel will charge at a reduced rate given a constant output of the charger. 50% is correct in...
  13. Problem with my '01 7.3L - weird noise

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Does the noise change if you go into neutral and manuver the truck side to side? If some variation, likely wheel hubs IMHO, the torque of turning will cause the pitch of the sound to change. If stays constant, could be propeller shaft bearing ,or rear end issue. Good Luck Coolhand
  14. What type of oil do you use in your 7.3L?

    99 & up 7.3L Power Stroke Engine & Drivetrain
    My mix 1 gall 5w40 Rotella Synthetic The rest 15w40 Rotella T Either Motorcraft or Fleetguard Filters. I find this mix helps negate the romps in cold weather, but is more economical than a full synthetic fill. 150K - oil stays honey brown till 4K mark, uses about 1 qty in 5K Oil and...
  15. crank but no start

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Hi, Being an 00 it may be the glow plugs or glow plug relay as well. I assume the WTS lite cycles? However easy to check the circuit. There are 2 relays just to the right of the fuel filter, the large one closer to the cab is your GPR. One large stud should always have 12 v from the bat, the...
  16. 2000 F-350 4WD Not Working :(

    99 & up 7.3L Power Stroke Engine & Drivetrain
    There is a connector on the t-case motor that can be removed, if there is tranny fluid in the connector, the t-case motor is likely gone. Other than that klhansen is spot on in the debug procedure.. Good Luck Coolhand
  17. poor start

    99 & up 7.3L Power Stroke Engine & Drivetrain
    Most batteries are rebranded by a handful of manufacturers. Johnson Controls makes a good battery. Costco sells these, and stands behind their warranty. I personally have had good results with interstate and Deka as well. Cost is a factor,however go for the highest CCA [cold cranking amps]...
  18. Looking at truck -01 f250 platinum 7.3 questions

    99 & up 7.3L Power Stroke Engine & Drivetrain
    I concur the Ford Platform is a better truck than the Dodge, I have owned a 97 Dodge as well - the front end on the dodge is problematic, however the ford may need ball joints and possibly hubs by now. If you can do the work - not too salty, but parts you are looking in the 800 region for both...
  19. batteries ran down now it wont run right? 2000 7.3

    99 & up 7.3L Power Stroke Engine & Drivetrain
    A search on batteries will yield a wealth of info, short story is you could have one bad battery. after charge, before start pull both grounds and 1 positive off of the batteries. check voltage on each battery. They should be 12.6 to 12.9 depending. If one is in the 11 volt or less range you...
  20. Mileage while hauling

    99 & up 7.3L Power Stroke Engine & Drivetrain
    I tow hay on 25' flatbed, usually grossing about 15 to 17K . With my 99 Dually F350 4WD 4.10 gears and stock 7.3 I typically was about 10.5 to 11.5, some hills, but not terrific mountains. Pulling cattle trailer at 8-9K at 70Mph+ over I-68 in MD and WVA I'd be at 10.5 -11 mpg. Speed and...
