Ford 6.7L Power Stroke Diesel :: Low Primary Coolant Level

I recently noticed a small bead of coolant on the driver's side of my tie rod coupled with low primary coolant level, so I took it to the dealer expecting to face a radiator issue (50k miles). Instead they said that the lower radiator hose was leaking and recommended replacement. Thinking that we were still headed down the radiator path, I had them do the job.

Upon inspecting the removed hose, I could find no obvious fault, so I inquired further. They clarified that it was the seal which had failed (I guess replacing the entire hose is the fix for this?), that it was contaminants that build up in the coolant which attack the seals, and that I should expect it to happen again if I don't flush the coolant every 10,000 miles (yes, ten thousand).

I asked if he meant to say that I should check the 'coolant additive level' every 10k (instead of 15k) and he again stated that a full flush was necessary every 10k miles and that it was a "maintenance intensive engine." This can't be right.

Ford 6.7L Power Stroke Diesel :: Coolant Level In The Primary Tank Low

2012 6.7 .... Noticed my coolant level in the primary tank was low. Thought it was totally empty but it had about a half inch left in it. Topped it off and also needed about a quarter inch in the secondary. I would say about a half gallon between the two. Truck was at about 36k. Has 37.5 on it now and haven't noticed any loss. Never smelled anything, no signs of any leakage. Oil looks fine. Is this 'normal'? Owners manual says to check and add. Never had this with a gasser or any of my tractors over the past 30 years. This is my first light diesel.

Ford 6.7L Power Stroke Diesel :: Primary Radiator Leak / Small Drip From Front Driver Side

I have approximately 66,000 miles on my 2013 F250 truck and noticed a small drip from the front drivers side around 40,000 miles. That random drip is now a leak and the truck will be going into the shop to replace the Primary Radiator.

I absolutely love this truck, but what a disappointment that this isn't a recall. What scares me is that my buddy who has a 2014 F250 will be going in for his second primary radiator in 3 years of ownership.

Ford 6.0L Power Stroke Diesel :: Speedometer Fluctuates Wildly - Charge Light Blinking

Idiot light was on for battery charging issues. Sanded all ground connections. Soldered battery cable connections. Scan gauge showed sporadic inadequate charging. Installed new alternator. Scan gauge showed sporadic inadequate charging. Installed new interstate batteries. Brought old alternator to be rebuilt, rebuilder said it was strong as could be, needed no work, high output alternator. Reinstalled old high output alternator. Scan gauge now shows charge output of 13.9 V to 14.1 V

Idiot light still on, flickers like a loose connection, sometimes lights constantly.Occasionally speedometer fluctuates wildly, when fluctuating like this at idle, the truck will stall, so far it restarts...so far. When it has stalled the speedometer still fluctuates wildly for a few seconds truck will restart and seem fines but this will play out again next day or so. Occasionally ABS light comes on, occasionally water in fuel light comes on and they go away after abit, some times after a restart, not always though

Thought it might be cam positon sensor however not certain with the instrument lights also acting as they do. Have had one cam position sensor open circuit code once, about to trip out west to Monatana & Colorado and back home to Ma in a couple of weeks, hoping not to be stranded somewhere in between those places!

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Alternator Rebuild - Charge Light On Intermittently?

My 2006 F250 has a single alternator and recently the charge light is on intermittently and I have watched output voltage fluctuate between 12.4 to 13.5 ... sometime a .3 volt bounce one way or another for no noticeable reason.

So rather than buy a new alternator, I would like to replace the voltage regulator and put in some new brushes.

What are part numbers that I need to pick up?

Ford 6.0L Power Stroke Diesel :: Battery Light Coming On And Then Going Off

My battery light has been coming on and then going off, just back and forth, for a few days now. The light stays on about 80% of the time. I have new batteries and the alternator is about three years old. I've checked the voltage from the alternator to the batteries while the light is on and I'm getting 13.85 volts on the multimeter. I've checked and cleaned terminals just to be sure they are corrosion free and right, I've checked the ground to make sure it's right.

Ford 6.0L Power Stroke Diesel :: Battery Light On While Driving

I charged the batteries fully, new alternator put in and checked grounds. Light was off, but while driving to work it came back on again and stays on. Battery voltage is 14.2 on each at idle and 13.4 while engine and key off. Maybe the two prong connector needs to be replaced?

Ford 6.0L Power Stroke Diesel :: Battery Light Went On And Off Intermittently

Running down the road today and the battery light came on. Went on and off intermittently as I drive home and the tuner showed 11.5v. Got home, shut it off (didn't mean to) and restarted it. Tested voltage at the batteries and was over 14. Need to take it for a drive and see if it repeats.

Ford 6.7L Power Stroke Diesel :: 2014 - Red Battery Light Came On?

I have 51k on my 2014 Platinum F-350 and the little red battery light come on. I take it in and they tell me that it is going to be a little over $1,300.00 to replace my alternator. I have had the truck since May 30, 2014 and the alternator has gone bad. I am regretting trading in my 1999 F-350 with over 365 k on it. Never had an electrical problem besides replacing the batteries every 4 years or so. Is this a common problem on these new trucks?

Ford 6.0L Power Stroke Diesel :: Intermittent Battery Light

Well today I got an intermittent battery light so I got the batteries tested and they were both good and then the alternator is only pushing 12 volts so I guess I need a new one right? Which know should I get? And how hard is it to get the belt to relieve tension...

Ford 6.7L Power Stroke Diesel :: Battery Status Indicator Red?

In the past I've had truck batteries last close up to 9 years but at 59 months one of my batteries is not looking that great. The battery status indicator is red. I checked the level of the side that appears to be leaking and it's ok. I've had no issues with starting and it seems to crank over just as fast as when new.

Ford 6.0L Power Stroke Diesel :: Battery Light Comes On For About 14 Miles?

My battery light is coming on in the mornings for up to about 14 miles. I am showing 13.2 to 13.6 volts with torque pro. The light hardly ever comes on in the afternoon, but sometimes. I had the batteries and alternator tested yesterday at Advance Auto parts. Alternator showed good both times they tested it. Batteries showed at or just above their rated cranking amps. I have inspected both negative grounds from the batteries, the engine ground from the firewall to the passenger side back side of the engine, and the body ground on the passenger side to the frame. They look great, tight, and have not moved in a long time. I added a cable from the alternator to the fender well and it showed about 7 amps while idling before dropping to about 4.5 amps. I am thinking of still buying a new alternator anyway. That is the only think I can think of. Worse case, I just have a spare in the back of the truck.

Ford 6.7L Power Stroke Diesel :: 2011 - Little Red Battery Icon Lit Up On The Dash

Our 2011 SD 6.7. 190,000 km Came home after a week off and started the truck up via the command start, when I got in it the little red battery icon was lit up on the dash. Well this is my 3rd SD and in the past I always ended up needing an alternator when that light came on. So off to the dealer and was about to replace it, the service rep. stated the alt. was ok and there was something else wrong and it was turning the light on.

So you think here goes my next weeks pay looking for the Needle in a hay stack. Guys the Tech who is a great guy found a 18 guage red wire that runs from the pass. side battery under and infront of the motor not in any real wire harness and it goes to the alt. had some corrosion forming in under the insulation causing some resistance, and it was telling the system to turn the dash light on.

The tech replaced the bad wire and all is good now. Also you can test the out put of the Alt. and it will show around 15 volts with the truck running even with the red icon on, so you will know it's the bad wire and not an Alt.

Ford 6.0L Power Stroke Diesel :: Positive Cables Of Battery Sparking?

I'm pretty new to working on cars let alone a diesel truck, so this could well be something simple and / or dumb. Hopefully it is.

Batteries recently replaced. Started cleaning terminals on driver side and realized I needed a couple of fasteners. Between getting them, the weather going bad and getting sick that battery was unconnected for several days, truck not driven.

Finished cleaning the terminals this afternoon, went to connect the positive cables and they're sparking. Driver side negative cable is unattached. Neither of the two positive cables sparks when touching positive battery post alone. They only spark when they are brought together.

Ford 6.0L Power Stroke Diesel :: Battery Voltage Dips Downs To 11-10.5V?

I spent a lot of time on the 7.3 forum, but I'm still new to the 6.0, so bear with me.

I've noticed that when I start my truck the battery voltage (as shown on SCT Livewire TS) often dips down to 11 or even 10.5 volts. The batteries are almost new, dated March 2016. When cruising down the highway voltage is about 12.7-13, sometimes a little higher. The alternator is also less than a year old
