I have been using this Engine Coolant http://www.motorcycle-superstore.com/item.aspx?style=12150&department=637&division=6#

Never thought about the lack of freeze protection much since the bike is always in my garage at night.

Now I'm getting ready to go ride in the NC mountains with about 50 of my KLR buddies and I am worring about freezing temps.
Is 30* temps enough to freeze the coolant in the block and should I change this before I go ?

Thnaks in advance

I just googled that product and it looks like it says it for race use and offers no freeze protection at all. No reason to take a chance, just change it out. You can always switch back once the warmer weather comes back.

30 isn't cold enough for a hard freeze, probably not any freeze since most additives lower water's freeze temp. On the other hand, I have no idea how thick the walls are in the water jacket. If you don't want to go through the trouble of changing it, if you warm it up good before turning in for the night, I doubt there is any way it could cool off enough to freeze.

99% chance it won't get cold enough to hurt anything, but is that 1% worth taking the chance?

32 is the freezing point, and I would think it would have to drop down to 30 or less to freeze hard enough to hurt anything. Even at 30-28 it would take some time for it to freeze hard enough to cause damage. They say the wind chill has no effect on freezing, but I have seen pipes freeze if a door was left open allowing the air to move freely across the pipes.

You know how many times the weatherman misses the prediction!!!!!!!!

You could also park it close to the campfire. Might want to make sure it's on the sidestand leaning AWAY from the fire though.

There is another product, called Engine Ice, which claims to offer both freeze protection and higher boiling points. It's usually available at local shops for around 20 bucks a half gallon. Pricey, but allegedly better.

Ride all night and sleep when it's warmer out.. :shock:


(sorry, I couldn't help it) :lol:


Drain or siphon a bit out of your radiator and add some antifreeze.. Even just a few oz. will help freeze protection. Just a thought..

If the KLR cooling system holds 1.3L or roughly 44 ounces. If you use 32 ounces of 50/50 premix and 12 ounces of distilled water you have a 63.6% to 36.4% water to coolant ratio.

If this is true what would the lowest and highest temperatures. I don't know and would like to know.

The reason I came up with this ratio is economics.

32 ounce bottle of Pro Honda HP Coolant Premix, $4.39
12 ounces of distilled water, $.07 ($.64 a gallon)

The coolant would be completely used and distilled water is inexpensive and the remaining distilled water can be used for other projects.

Not sure on temps but you could do this. Make a 66/33 percent sample from the antifreeze and water and check it with a float ball coolant checker and it will tell you the boil point you are safe too. For the $5 xtra bucks, I would make it all the correct coolant. Not worth tempting higher temps and having something go wrong with the motor, altho that scenario is probably on the extreme side.

I flushed the cooling system using white vinegar and distilled water. Mine was pretty clean and it took four flushes before it was very clean. Flushed the the cooling system twice with distilled water. Filled the cooling system with Honda Premix 50/50. Ran the engine through a couple heat cycles and topped off the overflow tank. Should be good to go for another year or two.
