Shell Dex-Cool antifreeze ???

[eastbayandy]

Just hit 8k and am going to do the valve check/adjustment. I have a bottle of this lying around, the 50/50 premix. Would there be any reason not to use it? it's red. looks to be silica and phosphate free.It's probably been lying around for at least 4 years.

Dex-Cool is something special that GM came up with years ago, and requires a complete flush of the old coolant when changing over. I wouldn't use it. Zerex Asian is the appropriate coolant to use

I couldn't find anything else in town but pentofrost A2. It's worked well for me

thanks, I'll just go to my local honda dealer and get the oem stuff.

Yes, will I get extra horsepower and unlimited radiator life if I use distilled or de-ionized water?!?

But.......... your water pump seal might like it.

Any reason you can't just use Prestone (or any other non-silicate antifreeze/coolant)? As long as it's changed at the interval, it should be fine, right?

Any coolant that meets the Honda standards non silicate, borate is the important part........it is likely way more important than the interval.

Some coolant manufactures play loosely with the meets vehicle manufacturer standards, safe for all vehicles and other claims.

The trick is reading the labels............if it does not specifically say no silicate it's not. Honda vehicles and many other Asian vehicles have a water pump seal that is sensitive to these contaminates. This goes back 35 or more years.

I am sure some owners just use any old coolant or just plain water and or other products with some success.

Alright, sounds good. Fwiw, their regular (AF-2000) coolant is silicate free, and their extended life (AF850) coolant is silicate and borate free, dex-cool certified.

Nope, but you may get pin size holes in your radiator....NEVER, EVER use distilled or de-ionized water in a radiator.

^^^^^^^^^^^^^
This was bad advise the last time you gave it in the last anti freeze thread !!! And contrary to the Honda premix coolant formula.

I don't care what they have on the label. Chemistry is chemistry and distilled or de-ionized water does take ions from the closest/nearest metal available-which is usually in the radiator (and I have seen it happen in lab experiments). If I saw this label, I wouldn't purchase it.

Honda's recommendation? This uncertainty is killing me. I'm removing my radiator immediately!

SORRY. But that is total BS. But everyone is entitled to an opinion.

 

[davidc83]

After doing some research, the anti-freeze replaces the ions in the de-ionized water, thus actually the mix of coolant with deionized water in the 50/50 mix, the water is really no longer de-ionized... The experts do recommend don't use straight de-ionzed water in radiators (but who does that). Sorry. I am done. Back to our regularly scheduled program...

 

[rippin209]

Sounds like a bull crap argument but it's actually good info, so thanks

 

[eastbayandy]

I didn;t mean to start anything, just was wondering if i'd be safe using the coolant I had lying around. Now I;m not even sure the overpriced Honda high performance motorcycle coolant I bought for $8 /qt is OK. I'm with greenboy, I'm taking out the radiator. should shave some weight too.

One uses distilled water to avoid mineral build-up. The other paranoia is simply lack of understanding.

East bay Andy, the plain yellow-bottle Prestone I bought a couple-few years ago for my NCX met Honda's stated requirements, and has worked well.
