![]() They are NOT making any money on green antifreeze, if anything they are reducing their own pay by advising to use green. They also explained the tremendous amount of warranty failures or these various parts I mentioned above. If I have problems, I'll let everyone know.Īfter reading those emails you received, I would like to reiterate.ģ different techs from 3 different dealerships are telling me about the problems caused by Dex-cool. I think I'm going to try RMI-25 and see what happens. RMI and water, but what I have works well. It's been in there for nearly two years, the gurgle is The dealer pulled my radiator (to change the harmonicīalancer.?) about 6 weeks later and I just added some more RMIĪfterwards.

(Why do I cringe at the thought of sending a Dex-Cool related post?) Suggest there are other factors involved. Don't want to get intoĪny flame wars with those who have had cooling system problems, but I would Magically turns into clay, or something like that. Yeah, yeah.I know there are people out there who believe that Dex-Cool low coolant levels, air in the cooling system, or peopleīelieving that you could actually leave it alone for five years at a time. The "problems" I've seen from Dex-Cool were all IMHO likely caused by I wouldn't leave Dex-Cool in for more than two years at the absolute most. > Just have to go back to the annual flush and fill. That car, every bit of extra cooling helps you run MORE BOOST ). Actually, I onlyīother with RMI-25 in two cars my wife's Z28 (which has a much lessĮffective cooling system than the Impala), and my '89 Turbo T/A (because on Wetter, which seems to turn slightly corrosive over time.

The population doesn't care but if you happen to live in the Mojave DesertĪnd like to tune turbo cars, for example (not that I know anyone who falls Manufacturers like Prestone don't pay much attention to this because 99% of RMI-25 appears to have some benefit in preventing this. To begin with, but it does happen, and your radiator degrades over time. On a car like an Impala or 9C1 that's got plenty of excess cooling capacity That reduces it's efficiency as a heat exchanger. Not corrosion) you can get a silicate layer on the inside of the radiator Mention is something called silicate dropout over time (even though it's One problem with most conventional coolants that nobody ever seems to You shouldn't have a problem with detonation anyway.

Not in the Impala, but I have used the two together in my wife's LT1 Camaro,Īs well as some other cars. > I'm wondering if anyone who has run Dexcool with RMI-25 has The RMI-25 protects the metal pieces from corrosion and electrolysis, lubricates the water pump and continues to clean.ĭuring our short winter (both weeks), I will use the green stuff (low silicone - not Xerex or Prestone which will cause gel formation) and return to the Distilled water setup. There have been many posts about the cooling advantage of pure water over antifreeze and the WaterWetter smoothes out the water so there are no hot spots. When fully flushed, I am going to run pure Distilled Water - RMI-25 and WaterWetter. ![]() I have been informed by my highly regarded tech who works on my car and also two more Chevy techs from various dealerships that not only will Dex-crap eat your heater core, it will eat your radiator and your intake manifold gaskets and plug up your intake manifold also. Have to be careful with this stuff as it is pretty agressive, but I want all the Dex-crap OUT! I will drain this in a month or so, flush with a bottle of Caterpillar Cooling System Cleaner (4C-4610) for around 10 minutes. Of course, I only drive mine once every couple of weeks to a meet or so. I put in a bottle of the RMI-25 a week ago, to hopefully loosen and clean the dex-crap before I flush. I'm beginning to wonder if you are not my long lost twin.
