| Post subject: | More on Evans coolant. |
When I metioned the Evans waterless coolant at the speed shop, and this is a fabrication and tuning shop primarily. They said they do not use it because the oil temp goes up with it. I did not persue the idea with them. I have already paid for, and intend to try it. But what about that? What does that tell us? ARe they guilty of missing something deeper here about heat transfer, and where and how it takes place. I did not ask if they used a hotter thermostat. What about an oil cooler? Especially for use with a turbo. My Corvette had one with an electric fan. I have run out of room in the front. Will one work under the fender or maybe up top. I hate to put more stuff high up ont his engine. Sam |

I suspect you will be the one to gather some real data. An oil cooler low on the passenger side could have nice short plumbing, and a thermal switch teed into the hot side switching a 10" fan. It would be away from the exhaust heat and you could even get the filter right side up at the same time. Over cooling in cold weather would not likely be an issue in this location either. I looked at the website for the coolant, one thing that does not look good for me is the lower temp limit. If I read it correctly it gets too thick below 32 degrees. Our dart is not a daily driver, but it gets that cold in my garage most of the winter. Every now and then I have to use the car, and I would like to be able to do so at any time without having to use a block heater ahead of time. One of the duties of a second car is to run without notice when the primary is down. This is a propylene glycol coolant, has anyone compared it to others? Like the common "Sierra" brand that is sold at the normal auto parts store? I am not implying anything, just asking if anyone has looked or has some info about what might be different. I really like everything else about the Evans coolant, and the price is not that big of a deal if it stays in there for a while. Just getting rid of the pressure should really make things last longer. |

Um...huh? :shrug: I don't have an oil temp gauge on my truck, but not only can I not imagine by what mechanism this what they claim could possibly be true, but it's also not a claim I've ever run into from anyone who's actually run the stuff.Quote: What does that tell us?
It suggests to me that they are making stuff up, or perhaps they have misunderstood what they think they saw, or perhaps they are simply parroting what somebody else told them about what they think they saw, or maybe they just don't have a good line of supply for this coolant and so they don't sell it and so they don't recommend it. I run into the other side of this last possibility all the time, because there is a lot of garbage available in the automotive lighting market. So even though I take especial care only ever to make comparisons and statements about various products that I can (and do) support with ample evidence, a lot of times people will assume I'm just calling a product junk simply because I don't sell it. In fact, it's the other way round (I don't sell junk), but because baselessly badmouthing the (nominal) competition is such a prevalent practice, people come to assume it's always going on.Quote: What about an oil cooler?

Regardless of what coolant you run, an oil cooler's certainly not a bad idea. That and/or synthetic oil, if you're not already running it.

The Evans coolant can be run at a higher temperature than water based coolants and there are advantages to doing so, but that's another discussion. If one does run the coolant temperature at say 250°F then the oil temperature will be higher as less heat from the oil will be rejected to the block and cooling system. I firmly believe that if you run a more normal coolant temperature then the oil temperature would not increase just from a change in coolant. |

I'm up here in the Frozen White North™, and I'm not worried about this at all. Go back to the big discussion thread on this coolant here; at -40° (40 below zero) this stuff is the consistency of a not-very-fresh frozen margarita. It does not freeze solid or anywhere even close to it; as soon as the engine begins to warm up it stops being even slightly slushy. Low-temp characteristics do not look problematic to me.Quote: This is a propylene glycol coolant, has anyone compared it to others?

Totally, utterly different products. Not even remotely comparable, except that both are engine coolants. Sierra (etc.) is just a reformulated regular coolant meant for dilution with water. Its only advantage over ethylene glycol is lower toxicity.

Stop it, Dan. You're making me thirsty and I can't drink until my wife delivers my new baby.
