This can lead to corrosion in the cooling system and the early demise of things like water pumps and radiators. The additive packages are mutually incompatible. Now there are at least a half-dozen variants. And just because they're the same color doesn't mean anything. And what if I had used a brand that was red? They never would have known and then what would have happened to my engine?Ī: Never mix coolant types. Is this true? It seems to me that anti-freeze is anti-freeze. They found that the water pump is leaking (which seems "early" with so few miles on it) but they also told me that since I added "green" anti-freeze to the Chrysler "red" anti-freeze, it would require a coolant system flush and that only "their" anti-freeze can be used in Chrysler vehicles. We had it in for a LOF 16-point Winter Service Special yesterday and I asked them to pay special attention to the cooling system since we'd never needed to add any fluid in the 3 years we've owned it. I noticed that the radiator level was low two weeks ago so I added a 50/50 mix of water & Prestone (we live in Washington State & winter's coming fast). Q: We have a 2004 Dodge Grand Caravan (bought new) that has 20,646 miles on it. Here's a cut and past from a popular mechanics website from a google search on mixing coolant types: Others say to use or not use other types for protection of seals etc. Many manufacturers say not to use that type. Some coolants, like the old green Prestone, have silicate additives. It's worked with other cars and saves me from paying some schmuck $69 to do it in a shop.Don't mix unless they're the same type of coolant, which is sometimes hard to tell. I drive it a week or two and repeat the process until I have used a whole quart of fresh fluid. I usually just siphon out as much as possible with aquarium tubing - then refill it with new fluid. I will eventually do the power steering fluid myself, too. That's something I would not do myself - as I don't have any way to suction it out of there. He said that the rear differential change would run either $39 or $59, depending upon whether or not it requires synthetic oil. Since I'll be keeping this truck a long time, I figure it is a wise expenditure if it will lengthen the service life of the truck. Even so, I will probably get it changed (messy job?) just for peace of mind. It looks nice & pink and I believe GM calls for 100k change intervals. Regarding the ATF, I cannot tell if it has ever been flushed out. I suppose it will be okay to keep using the orange stuff and flush it out every other year (as I have always done with every car I drive), right? Sounds to me like mixing them is a bad idea! Perhaps I will just buy two gallons of Dexcool Wal-Mart (about eleven bucks apiece + two gallons of distilled water) and flush it out myself in the back yard - and I won't stay awake at night worrying if I didn't get all of the orange stuff out before changing over to green/yellow coolant. Some of you on here said that the green/yellow stuff and the orange stuff will break down each other. He said that their coolant is as good as or better than any OEM stuff. The label on the drum said it is "compatible with any vehicle & any color coolant" - including GM/Dexcool. They use green/yellow Pennzoil stuff out of a 55-gallon bulk drum, and don't carry any other type - nor do they have the red & pink stuff used by Toyota. The chap said that their TransTech Dexron ATF replacement would run $99 and that the coolant flush & fill would be $79. When I change the oil & filter, I'll go with a synthetic - probably Mobil-1 or Castrol Syntec in 5w30 viscosity. I still do my own oil & filter changes on all of my vehicles, though (which I'll do on the Silverado in another month or so - but the oil was just changed 500 miles before I bought it). They've come in handy for manual transmission gear oil & differential fluid changes. There is a Jiffy Lube franchise nearby, which I have used several times with various other vehicles to do just about everything except oil changes. It has the orange stuff in the reservoir and I am assuming that it has never been changed & flushed out so I intend to do that very soon. I have a 2004 Silverado LS 5.3L 2wd which I purchased several weeks ago with ~ 75,000 miles on it. Okay.I have seen some back & forth comments from a few folks regarding the GM 'orange' Dexcool anti-freeze versus the old school Prestone 'green' traditional anti-freeze that has been around for decades.
