DC says no to PG antifreeze

[John Berger]

It's rather interesting that Fleetguard, which is owned by Cummins sells the pre-mix in both PG and EG formulations for all series of Cummins engines, including the ISB. I don't know how much difference 5 degrees would end up making if the coolant got as hot as all of that. I know for a fact I would notice my temps rising and have the vehicle shut off long before I got to the point where serious damage might occur. I have alot of confidence in a product that is manufactured by Cummins for Cummins engines. What DC's reasoning is, I would not even venture a guess, but I'm sure that to them, it is well founded. I'm really interested in what others may have to say about this and what your experiences/opinions are? I would also note that while not related, I had our local dealer tell me that if I ever had a rear-end problem, that I would be up the brown creek without a paddle. Guess why? Because I have a Mag-Hytec differential cover on my truck. #ad
On the surface that attitude is understandable, but when a wee bit of thinking is applied it becomes much harder to understand. I know that this is comparing apples to oranges (dealer opinion v. service manual) but I still think this is a mindset that permeates DC. Remember, for whatever nuances in legal bovine scatalogy used in warranty discussion, the engine is not a Chrysler engine. Chrysler warranties the vehicle, but Cummins warranties the engine. I feel comfortable using a Cummins product in my engine and I know there are others here who would echo that sentiment. My 3 cents on the matter.

Sorry Paul, you need to search further... DC issued a TSB several years ago stating Propylene Glycol can be used in place of Ethylene Glycol antifreeze/coolant. Guess who doesn't market a Propylene Glycol antifreeze/coolant? That's eight, DC! Hmmm.

Another specific point to remember is that the 100,000 mile warranty on the engine is between us and DC, not us'ns and Cummins. DC may have some sort of corporate warranty agreement with Cummins, but if there is a problem with the engine, you have to duke it out with DC. Reading the fine print is a pain in the butt, but it only really hurts when you don't read it.

DC buys the engines with out warranty from Cummins. they are cheaper that way. That is why DC will restrict the engine or drive train warranty in less than a heart beat, Every declined engine warranty is money in the pockets of the MB employee in lack of productivity bonuses. #ad

This is with reference to thread by John Berger posted recently. My 1999 Ram Truck service manual page 7-10 propylene-glycol formulations should not be used in Crysler Vehicles. PG has 5 deg. C higher freeze point than EG. Also boiling point of PG is 257 deg. F at 14 PSI compared to 263 deg. F for EG at same pressure. PG also has poorer heat transfer than EG.

Isn't this board great. This kind of information is exactly why I post and read here almost everyday. A TSB has been issued superceeding my information. Where but on this board could you get that fast of response and that easily obtained. Thanks John. Just for records do you happen to know the TSB#? If the increased wetting of the EG is true though; probably stick with EG.

Paul, I found this information out about two years ago. I will look (once I get home) to see if I still have the copy I printed out. If not, it will require some research for the number.

 

[John]

AHA! I found it! Paul, it's TSB 07-03-97

Check out the date... it's been around since 1997.

Thanks for the info John.
