I just started having the interior water leak issue. I swear if I end up having all the problems others are having with these trucks, it will be a Tundra for me too.

There is something going on here. I took my truck in got the ole' "Could not find symptom" "Could not duplicate" and got a chance to talk to the technician. Its funny it seems like the service writers and managers ALWAYS try to run interference or try to keep you away from the tech altogether. The tech told me that he pressure tested the system while hot and it held pressure. He also said that he had not seen any radiators that were cracked like that. So this for now will be an ongoing issue for me.

Just checked my DC 5.3L with ~13,000 miles and no cracks. Hmmm...

Do you have the max trailering package?

Hi there, first time post here. I just picked up my 14 in 12/17 and have noticed since I got it the coolant is down about an inch in the resovoir and my driver side is cracked. Just dropped it off at the dealer this morning and was immediately told there is no tsb and they've never had to replace a radiator in one of these yet. I showed the service advisor the,crack and he said that it's just a mounting tab and that it has nothing to do with coolant loss but they would check into it. I told him that the coolant must be going somewhere.

 

Now, I am a professional mechanic,by trade (heavy equipment/ buses) so I'm not going to let them pull anything over on me.

 

Btw, 25k on the truck.

      Uh yes, that's the name of the package. It doesn't quite bring it up to 1 ton specs unfortunately and imagine they have to do that for a numbers reason rather than a physical one.    Am I correct though that the Max Trailer Package and therefore the 12" rear is only available on the Duramax and not on any of the L8T 3/4 ton trucks ( and that the same 11.5 rear axle center section is used on the 3/4, 1 ton SRW and even 1 ton dually gas version ) ?   I'd also be curious to know if the wheel bearings are the same on a SRW configuration between an 11.5 vs the 12" diff as I assume parts would show that up but may not explain what the difference is if indeed there was a physical difference.

      Mobil up another dime this am , $3.89, others will probably go up later. Any ideas on the reason for the increase other than greed? I've been working 14 hour days and haven't caught the news in a few days.

      AMSOIL SS is about prevention and it is very good at it's job. I've never seen it claim to be a cleaner however like Valvoline R&P. Almost any oil that has some Ester or Alkylated Naphthalene in sufficient quantity will do a good job at keeping the rings functional.     I see the market splint among these types in two groups; those that use the same tech in every weight grade and those that reserve the tech for the EPA (EPA) friendly grades. Mobil 1 for example keeps the Advanced Clean chemistry out of the SAE 40 and up weights. Other like HPL (top shelf group and No-VII), Red Line HP, TORCO, MPT30K use the tech in all grades. Just not something the Wally World oils are into.
