As I have posted, my truck broke down in Dallas, TX with a Tone Wheel and starter failure. Finally got the truck repaired and towed my TT back to Charleston, SC.
Seemed to tow ok and engine/oil temps as before with as much as 30 degrees delta between water and oil temps.

While in the dealership in TX, the EGR was replaced also.

After getting back on Friday night, did not disconnect or move the truck until this morning. Checked the radiator and.....DOWN OVER HALF A GALLON of ANTIFREEZE!

WHAT??
Check for leaks...nothing to be seen.
Filled the radiator back up to mark and ran the engine down the highway watching for temps and thermostat openings. Seemed to be same as usual with thermostat opening around 200 degrees and delta between water and oil increasing.

Soooooooooooooo...... Three way value? Water pump? Hose to turbo? Radiator hoses?

No leaks showing up either on the truck or on the ground.
Currently waiting for engine to cool down to see what the overflow tank will show for coolant.

Checked the overflow tank when I picked up the truck and also ran it for the next day, around Dallas, to make sure it was holding up. It did with no signs for any problem(s).
Checked it again before pulling out of Dallas and it was right on.
Note: even on the repair statement, dealer noted they filled the radiator with antifreeze.

So, after driving the truck for a while, letting it get up to normal operating temps, came back home and found a damp floor under the passenger front seat mat. Carpet is damp.

Soooo,
1. Heater core
2. hose issue to heater core
3. A/C evaporator
All are located in the dash, passenger side.....I think???

Anybody done any work in this area or had any problems with this?
I search youtube but didn't find anything specific to our trucks.

IF your following this thread, the SAGA continues for sure!

Well,..............believe it or not, the truck failed to START!!
As you may know, I was in TX on the 22 nd. of July, the truck failed to start. LONG story, but the dealership was able to get a new starter and a EGR and a Tone Wheel replaced. Got the truck back and all seemed well.

As this thread started, finally got home on Aug. 5th. only to discover on Aug 6 that I have an antifreeze leak somewhere, with antifreeze both leaking outside close to the firewall and inside front passenger cabin.

NOW, today, the truck is AGAIN FAILING TO START! WHAT!!!>>>?????
Same symptoms as before, out in Texas.
I ran the truck for 200 miles yesterday with 5 starts and stops. No problem
Today, went 60 miles with 3 starts with no problems.
On the fourth stop, after sitting for maybe 2 hours, push start...just a grunt.
Waited about a frustrating 10-15 sec., no start just a grunt.
Waited about a min., no start just a grunt.
Waited another frustrating 3-4 mins.................. STARTS RIGHT UP LIKE NOTHING IS WRONG!!

As you know, I replaced the battery, the started, EGR and TWheel as a result of this "symptom" before.

When it "grunts", its all the world like a discharged battery. Wants to think about starting, but can't even turn the engine over one time. No "clicking" of the solenoid, like you might get with a dead battery. Just the grunt try to start.

The only thing I can see that has changed in all this time of challenges, is the voltage display on the dash. As I've mentioned before, all the 4+ years of having the truck, the display on voltage would read 14V. Never changed .

When I first started having a problem, I noticed that the voltage readout has changed to 13 volts. When I start it up, it show 12v and very quickly jumps back to 13v. Does not change with A/C, Lights, heater, radio, everything I can turn on.....just stays at 13v.

ANY ideas what the heck is going on??

I would agree that it may be the alternator, but when it does start, usually within a couple of mins., it starts strong and the battery is new. My mind wants to say that even a weak alternator, shouldn't show a strong start at any point. I'm not that great at auto mechanics, but my thinking says that the alternator really only works to boost the electrical and charge the battery. IF the alternator is always showing 13v, and if the battery is new and the when it does start it starts strong, just seems strange that a weak alternator would be the problem.

I wonder if the alternator can have a "flat" spot, like a starter and if/when it stops in the ??position?? it then has to have a few "bumps/grunts" to move it enough?

Does that make any sense? Not sure alternators work like that but ????? I'm at a loss for sure.

That would show something for sure, but since it is different each time as to how many attempts it takes to start I'm not sure how long it might take to find a specific issue. With that being the problem, I'm also guessing the dealership is going to say the same thing. Starts every time they try and until it totally fails they can't do anything. Got to love intermittent problems for sure.:(

As my mother use to say "back again, like a bad penny"!
At any rate, this saga is getting really old.
The truck continues to "sometimes", refuse to start.
The sounds have changes, AFTER I had the s/w update installed for the computer. Now, instead of just a "grunt" and not even one engine revolution, the engine tries to start and gets maybe 3-5 revolutions while sounding like something metal is grinding. Really sounds bad.

Again, this no start may only happen the first time or may take two or three times, but when it does decide to start up, that instance starts up with no problem/quick and nice as usual!???

Again, still no start at times as before, BUT, the attempt and sounds has changed after having the tone ring s/w update installed.

HERE IS A QUESTION MAYBE SOMEONE CAN ANSWER: I reviewed the paper work from Dallas when we were stuck waiting for a new started and tone ring install. The paperwork says nothing about replacing the "sensor" for the tone ring. I'm just wondering if:
1. Are both the tone ring and sensor supposed to be replaced at the same time?
2. IF the sensor is replaced will it show on the repair order? (my RO shows nothing other than just the tone ring).

Any ideas, again, would be appreciated.

PS: Tried to attached the sound file off my phone of the engine attempting to start, but while a short file, it's 21mb and to large to load.

You may be right on the coolant/cyl. thing. There has not been any white smoke or any other smoke thought.
As far Hot Shot, I've been adding it to every tank fill for the past 2/3 years. Agree it can't hurt but doesn't seem to help.

I just sent off an oil sample to Blackstone. I mentioned to them to certainly check for any water in the oil. Should have an answer tomorrow or Friday.

Well, the dealership replaced the EGR. Why, not sure since it was replaced in July, but they did and it still is showing coolant lose. Nothing showing on the ground or engine, ever, BUT, in their wisdom, they are ordering a coolant overflow tank and think that is the problem. Doesn't make any sense to me and I ask them why. Their answer.......because.


I guess we will see. They expect the new tank on Tuesday next.

We continue!?
RECAP:
The EGR was replaced in Texas in July/Aug (had to wait 3 weeks for parts.
Drove back home from TX and continued to has both coolant loss and no/bad starting.

Dealer in Charleston took the truck in late Aug. and could find no problem.

Took truck back in mid Sept. reporting coolant loss and starting issues.
Dealer could find no problem.

Took truck back two weeks ago to dealer with coolant loss and starting issues.
:(:(
Dealer could not find a problem.......Sooooooooo.. Filed the overflow tank in front of the Service Mgr.
Drove home and in the morning sent pic to SM showing coolant down about 1/2"
Drove about 50 miles or so and next morning sent pic to dealer showing coolant down about 1.5"
Drove about 230 miles and next morning sent pic showing the coolant almost totally gone from the tank.

Refilled and took back to dealership.
Even longer story, but no going there BUT:
Dealer replaced the EGR thinking it was cracked...and reported it was.
Leak continued.
Dealer replaced the coolant tank.
Leak continued.
Dealer checked the the EGR, again, and it was cracked again????

During this time before the last leaving of the truck at the dealership, changed the oil and sent a sample to Blackstone.
Blackstone just reported antifreeze in the oil by a significant amount.

This is the 5th report over 45K miles and the first time the report hasn't been excellent....per Blackstone.

Dealership is getting other master mechanics to look/hear/report on engine.

As for the start problem.......dealership thinks its a bad starter.....even though a new one was installed about 3k miles ago in Texas.

To be continues.....

Engine failure. Dealership sent a request for replacement to MoPar. Truck has 96.5K miles on the 100K MP warranty.

Guess I just have to wait and see what happens.

I do have the extended MoPar Warr up to 100K. Current milage is 96.5K

I don't know why they wouldn't, but there does seem to be a lot of challenges reported on the forum about denied warr claims.

I guess will just have to see what happens.
