Coolant type recommendation needed
« on: October 07, 2020, 04:58:22 am »
Hi there
I am planning to change all the fluid for the new to me 09 concours,
But I am still confused about coolant type. The service manual said “permanent type antifreeze, color green”. What kind of coolant exactly is needed? IAT, OAT or HOAT? I would like to use lower cost stuff because I want to flush the system a couple of times in case cannot drain all the fluid out.

BTW, do I need to replace coolant hoses per service interval? The bike only has 10.7k miles, but manual asks for hose replacement every 3years.

Again, appreciate all the help from the forum members!

I've always used the pre-mixed Honda coolant, but if Kawasaki has pre-mix then I'd look at that as well.

I've been using Honda coolant since my bikes first coolant change. This stuff started out green but has migrated to blue.

By the "green" type they mean Ethylene Glycol type with corrosion inhibitors.  This covers most of what you'll find at any auto parts store that is NOT labeled "Dex-Cool".  It does not have to be green but some of the major brands are green.  Dex-cool is almost always red and should NEVER be used in a Concours!

I like EngineICE or similar which is Propylene Glycol based and meets all the requirements that Kawasaki has for coolant (EngineICE guarantees this) and it has the benefit of being far less toxic than Ethylene Glycol coolant.  I have not noticed that it performs any differently in my bike.  Its color, is blue, which is OK with me but be sure to thoroughly flush your system before adding any as it doesn't mix well with the "green" stuff.

I don't like to buy the premixed stuff because it's nearly 2X the price of the concentrate.  But always use distilled water to mix, not tap water.  Around here distilled water is about $0.50/gal. so that's a lot cheaper than what you pay for the 1/2 gal of water in a gallon of premixed coolant.

That is what I ended up using also.  It is "blue"

I like the Honda stuff.  Cheap and readily available at the LBS. 

And yes, I replaced the hoses after a few years and a bunch of miles. 
Like eight years old and 120,000 miles or so. 
It is the time, not the miles.

Yeah, I am thinking I made a mistake to not go ahead and replace the hoses when I did the major service last year (at 8.5 years old) and everything was open and drained.  Probably would have only taken 30 min or something.  Now I have no idea when/if it would ever be done.  Oh well.

My C14 hoses are 13 years old and look like new. They still feel flexible and no sign of any damage or decay.
I know the hoses on my C10 went hard with age, but even those didn't get replaced until they were 25 years old.

I've always used the Blue type coolant in my Kawasaki's as recommended in the manuals. Just mix it 50-50 with deionised water.
