Hi for the past couple of weeks ive been smelling antifreeze from the cab of my truck.If the truck is idling or if i am driving on roads i do not smell it once i hit 40 mph or more on the highway i start to smell it.About a month ago i went upstate about 2 hours from my house.I went riding the next day i went to go start my truck it wouldnt start only cranking.I had it towed 2 hours back to my friends shop he got it started and only did a oil change.I dont know if the antifreeze problem has something to do with the not starting problem but i figured i put it down.If you guys have any idea why im smelling the antifreeze it would be a big help thank you.

 

Moved to the 6.0L Power Stroke Diesel forum.

 

Start with the simple things first. The first item I'd check or replace would be the resevoir cap. Could be letting vapors out and they get ingested into your vent.

Also, are you losing coolant and/or have signs of coolant puking (i.e., white chalky residue on or around your resevoir)?

 

I checked the coolant today and it was low so i put some in.Also when the truck was in the shop a month ago i filled it up.

 

I will check for the white chalky residue on my resevoir tomorrow.

 

A little trick I heard from a 6.0 owner. Rent a coolant system tester. Pressurize the system to 16 psi. check for leaks under the hood and below then if you don't find any have somebody start the truck. If you notice a coolant smell coming from the exhaust then you have a problem in the egr cooler sytem ( egr valve, cooler, etc).
Good Luck

 

Thanks to everyone that is helping me out.I checked today for any white chalky residue and didnt find any.

 

First off Welcome to FTE

Park the truck Nose down and pull the EGR Valve look inside the EGR chamber in intake manafold for sign of coolant

Keep an eye on the coolant bottle for coolant leval and check it when you get home from ddriving it sometimes those coolant bottles crack along the Tank seam you may see it leaking from there

another thing to do is get some gauges I use a scangauge you will just about be able to check everything with it Mainly right now would be the oil cooler because of the symptoms and it can also tell you the FICM voltage you will want to check that along with the High Pressure Oil a HPO leak would also cause a no start and 05 is famous for that STC fitting going bad but its usually no start hot

Gauges is your besst bet cuz as you can see theres alot of diffrent ways this could go

 

That was going to be my second recommendation, especially with the loss of coolant.

 

Hi Guys I went to my friend and had him put his OBD11 computer on my truck these are the codes that came out P0528 Circut fan speed sensor NO signal P1000 OBD11 System checks Incomplete P1102 MAF LOWER IN RANGE THAN EXPECTED AND P1408 EGR FLOW OUT OF RANGE i figure that my antifreeze problem has something to do with egr since the code came up.

 

I think your antifreeze problem has something to do with your fan problem P0528

Is your egr valve plugged in cuz that can affect fan operation too

some of those codes wll go away when egr problem is fixed since its emission related
