Hi All, I have had my 2010 CRV for 3 years and I think it's time to drain my anti-freeze and replace it. How often do CRV folks change the anti-freeze as a rule? Do you first run a jar of radiator cleaner through it? Thanks for any input. :)

Check the owner's manual for recommended interval. As to changing it, just drain it and replace with fresh. Dispose of the old stuff properly. If you flush with anything, on a three year old car, plain water should be sufficient.

Your '10 CRV came with blue HOAT antifreeze, which creates MUCH LESS buildup inside your radiator than the old coolants. Look inside the radiator cap if you don't believe me. ;) It will look like new, no crusty scum as was common 20 years ago.

I believe your MM will throw the coolant replacement code at about 110K miles. If you don't drive too much, a 5 or 6 year interval, based on time, is fine. :cool:

WOW! Coolant replacement at 110k? Doesn't it break down after a period sooner than that?

Nope. OAT and HOAT coolants are "Good Stuff".

Who remembers the regimen of filling and draining a cooling system every fall and spring? (I don't. 'Least, I won't admit it) ;) ;) ;)

I remember when I first read that in my '02 Accord's manual. Blew me away as I'm an old fart that used to change it every year or two. I didn't open the radiator, ie pull the cap off, but one time in the first 100k miles on that car, and it still looked like new coolant!

I've never seen OAT/HOAT in the store. Probably because I didn't know of it. What brand names is it under, how much is it, and who typically carries it? Thanks in advance.:)

I'm not sure you can get OAT/HOAT like is put in at the factory.
Even Honda recommends changing the fluid (using their own brand) every two years after the original stuff is removed.

Too bad. I was thinking of putting it in my Wife's Subaru when I change the fluid in a few weeks.

The sticker under my hood says to replace according to the MM sub code 5, or 10 years which ever comes first, then every 5 years after that. Use only the Honda type II coolant.

Then probably never for the original owner.:)

For the most piece of mind, you can buy Honda Type 2 pre-mix coolant from a dealer. That's what I do. ~ $15 - $20 a gallon USD.



Zerex Asian Coolant is about the same price. It also comes pre-mixed. NAPA stores carry it (but you might have to ask them to ship it in, usually next day)



There are other HOAT and OAT coolants, usually the amount of silica and phosphorous differs differs according to OEM specs. Zerex actually sells five different formulas of coolant for different vehicles and makes.
