So, what type of coolant should I use with this KLX? Type 1,2,3? I know two does not silicates. But is there any massive concern for using whatever I can find?

 

Not sure what type 1,2 or 3 means.
The '09 service manual calls for: "permanent type antifreeze (for aluminum radiators)".

 

Make sure its ethylene glycol. Type A Mixed 50/50

 

(Somebody tell the OE there's not such thing as "permanent" coolant. If coolant did not change composition and require replacement, it wouldn't be doing it's job... Yes; even the "lifetime--OAT formula" stuff. Yes; you can add re-fresher goop to help restore the nitrite levels, but sooner or later, you need to flush/fill.)

 

I just flushed mine with normal 50/50. Thanks for the replies.
