I'm debating using this when I flush my coolant. I know a lot of people like to use strictly OEM fluids and such (I am one), but anyone experience any ill effects using this stuff on their Honda? Any harmful ingredients that would do more bad than good?

 

bump, anyone have any input???

 

I've used it a few times. It can definately wash a bunch of crap out of a dirty system. I'd like to see before and after shots of the block coolant channels sometime to really see how well it works. Fill the system afterward with distilled water (only when it's well above freezing outside) and run the car for an hour or two to rinse the last of the crap out. Drain and refill with 50/50.

 

I've seen and used non-OEM coolant used many times. As long as it's flushed and changed perodically, you should be alright. I'm running AutoZone 50/50 green coolant in my DC2 and don't have any problems.
