Batteries

[PWRSMOKE]

I dont know if this is a problem or if its common but when i go out to start my truck in the mornings and it was about 13 degrees f with a windchill of 0degrees this morning and when i turned it sounded like the batteries were real weak...but it started...it just took it a sec cause of that...i know cold is hard on batteries...but im just wondering if it gets colder if they will completely fail or what...they are brand new duralast gold batteries...with 1000 cold cranking amps each..TIA guys

Plug the truck in and let the glow plugs cycle longer before you crank it.
I would have the alternator tested too.

If you have new batterys, make sure all the connections are good. if so then i would lean toward the starer draging. I just had to repace one on my service truck. It was also hard to start in the morning kept getting slower everyday. Put a new one on there and strats like dream

Also something to think about. Weak batts will kill a starter. low voltage means high amps which kills it. If you just replace your weak batts it may have drug your starter down. Hope that helps

I replaced my starter with a gearreduction starter I got at carquest..made it spin faster works great...Oh this was on my 01 psd...

i have had the same problem with my 96er when it gets cold. just not as cold as what you are having. i think it has to do with the glow plugs drawing so much power. use your block heater to help out.

If its a 6.0, the plug is behind the bumper, insie the passenger side tow hook hole.
If its a 7.3, i think they are up by the drivers side headlight.
