i just need a quick run down on how to drain and replace coolant in my 2003 636, and what kind of antifreeze to use. i wanna make sure my coolant system is in great shape b.c its really starting to get hot where i live. thanks

 

Since your bike has an aluminum radiator than make sure you get coolant made for aluminum radiators, some is made for any metal. The automotive stuff has a corrosive material that scurbs the inside of the old metal radiators but will eat a hole in aluminum. If you don't buy the ready mix just mix it 50/50 with water. I like to use WaterWetter with the antifreeze mix also. Since the bike isn't that old, you probably don't need to use a "flush" system but it is always good to do. It's another product that you mix with water and run in the cooling system for a little while and then flush it out with straight water.

 

Honda 50 / 50 is pretty good. My favorite is Engine Ice. Hotter than hell in S.W. Florida and my fan never comes on.

 

is 1 bottle of antifreeze enough.

 

My 05 ZX-6R takes 2.7 quarts which is just over half a gallon (4 quarts = 1 gallon). Since your mixing it with water, you only need 1-1/2 quarts, but I think the 1 gallon jugs is all you can buy. Pick up a measuring cup too if you don't want to mix the coolant in the jug.

 

does the engine ice offer good enough protection from freezing... being from NH it gets a little cold up here in the winters.

 

Im gonna change to water wetter next week. right now ive got straight antifreeze andmy bike temp still gets pretty high. Louisiana really hot.

 

you shouldnt run straight antifreeze.

 

Says on the bottle "freeze up protection to -26 degrees F".

 

ok im gonna do it later on today. I dont know where my head was just realized what i did. i guess i was to busy trying to figure out what was up with my fan not coming on. sad part is i would never do that to my truck, and i love my bike a lot more than my truck. thanks for the save candylighting. hope i didnt mess anything up.
