Cummins shops are on par with Chrysler shops they just call them diesel mechanics instead of auto mechanics.



The local Cummins place near me is really a pain to deal with, I went in with part numbers for a 180 degree thermostat and two other things and it took me half an hour. They have my engine serial number and they guy just about wouldn't sell me the 180 degree thermostat because that's not what his computer said my truck took, oh the other thing was a stratopore filter, it wasn't listed on his computer as being the one for my truck. Finally I said just give them to me and let me pay. Getting a cam position sensor was a half hour job to, no waiting in line parts guys are just retarded.



I switch to the G-05 zerex last year, found it at Auto zone for half the price of the Fleetgard stuff. Both the Fleetgard EG and PG have the DCA additive package, it's not needed but doesn't hurt. These coolants are all ok to mix together but if you system hasn't been thoroughly flushed then throw the 3 year life stuff out the window, any extended life is out the window when they get mixed.



RBattelle good job at keeping your cool, I would've been a little hot under the collar especially knowing I could do it myself for $25 and a couple hours time and most places take used coolant now for free.

I know it isn't the main topic but ethylene glycol antifreeze is VERY VERY poisonous to pets and wildlife. I know it was a joke about dumping on the neighbors lawn, but store and dispose of anitfreeze safely.



Propolene (bad spelling? glycol is much safer for pets and wildlife. However, to be safe still store and dispose of properly.



Because Mom says so!

LYNN TURNER just got convicted and sentenced to life for the murder of one husband and implicated in the death of a live in boyfriend for murder by ethylene glycol poisoning.

So I happened upon this text in the 2003 Dodge service manual:

Use of propylene-glycol can result in boil-over or freeze-up on a cooling system designed for ethylene-glycol. Propylene glycol also has poorer heat transfer characteristics than ethylene glycol. This can increase cylinder head temperatures under certain conditions.

Based on my calculations, there's no way I can boil over PG as long as I keep the temperature below 245°F (redline on the gauge). Shouldn't be a problem.

But I was intrigued by the part that claims PG has poorer heat transfer characteristics than EG. So I went on a search, and I can't find anything that mentions that. I mean, EG and PG are both electrolytic solutions. When mixed with water, they depress the freeze point and raise the boiling point an amount proportional to their concentration.

It's unclear to me how the subtleties of each formulation would impact heat transfer between the iron and the water. Like I said, in a quick search I couldn't find any data regarding the relative heat transfer qualities of EG and PG.

Anyway, I looked over the relevant Cummins bulletin. It makes absolutely no issue regarding either PG or EG, and says either one is acceptable in their engines as long as it meets CES 14603 (which mine does).

I thought it was interesting reading.

This article mentions that ethylene glycol has better heat transfer properties but in table 2 it looks like the flow increase vs water is greater than that required for the propylene glycol and that doesn't make sense to me.



Correct me if I am reading that wrong, I have been at work since 6 pm Sunday with only about 4 hours of down time, only 3 more hours to go and I will have worked 32 out of 36 hours:{till the check comes



This Google search came up with some stuff, and most seems to point at ethylene being better especially in cold conditions but for us common peasants I don't really think it would make that much of a difference.



Both of my trucks are running the G-05 HOAT stuff, it gives me a warm fuzzy and is semi easily available.

An odd chart, that does seemingly contradict their contention that the thermal conductivity of PG is lower than EG.



Also note they specifically prohibit the mixing of EG and PG. Fleetguard told me on more than one occasion that there are no known chemical incompatibilities between their EG and PG products and any other product on the market.
