Don't worry too much about all the negative, "sky-is-falling" rhetoric on Dex-Cool
Seems like good stuff. Don't worry too much about all the negative, "sky-is-falling" rhetoric on Dex-Cool. Here's some professional advice (I work in heavy industry and deal with chemicals and heavy machinery all day, chemicals break down overtime. In the process things like pH can change as will corrosive handling capabilities. What I'm saying is nothing lasts forever. So change this stuff out like you're supposed to and do a right-proper flush. If you flush with hose (city or well) water as you most like will, pour some distilled water in to flush that stuff out. It's cheap by the gallon at any grocery store.

Driscoll's great, but what a mess!
McCool is fine so long as you don't mix it with the green stuff. Using the green antifreeze can (and did) cause the engine to produce an electrical field that wreaks/ed havoc on various sensors.Some packaging feedback for Amazon: a bottle of of this arrived 20 minutes ago and the bottle was leaking all over the protective bag inside the box. Upon inspection of the the half-full bottle, I found the leak in th side of the bottle. You usually provide more than adequate packing material, but this time there was none and half of of my product is on the inside of of the protective bag (at least THAT served it's purpose).This will be the last time I buy automotive fluids on Amazon.

Just what i needed!
Used in my 08 cobalt. Works in GM vehicles. DO NOT MIX THIS WITH GREEN antifreeze. This is what GM vehicles should take. I did this as routine maintenance at 100k miles. Fluids are cheap! I like to replace them before they lose effectiveness and cause more expensive issues.

Must have in my shop.
I like to keep some around, with a lot of vehicles now using o-rings and couplers you never know when an o-ring will just give up and you have a nice little coolant leak. This is what came in my rig new and this is what I'm staying with, so far no corrosion problems.

Not much to say. I must use this product ...
Not much to say. I must use this product for 2 of my GM vehicles. It has performed well. Just never mix in the green antifreeze and you will not encounter issues.
