As some of you may already know, I recently switched to Engine Ice as my

coolant. Tonight was the first chance I've had to ride since the change. 78

degree's outside. I went for about a 45 min. ride, for a total of maybe 20-

25 miles. Went I got back to my shop the temp. gauge was at 10 o'clock

(not a problem) and the fan came on when I shut the bike off. When the fan

shut off, I could hear the coolant boiling.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/eek.gif ALT=":eek"> Every coolant line was hot as

hell and you could feel the coolant boiling inside. It was a very easy ride

never getting above 6-7k rpm's. I can't figure it out.

Most definitely sounds like baby needs to be burped to me. But I don't know squat about the Engine Ice yet (although I am getting ready to buy it from what I've heard).. It took me 2 times to get all the air out of the system after my last coolant change.



I'd be most interested to hear the outcome.

I'm almost certain I got all the air out. Probably not though. I'll try it again

tomorrow and see. I sure hope that's it. It's almost gotta be.

I was sure I got all the air out of mine too...



After I did the mods she was running way hot. It took several hot cycles/cap off to get all the air out of there.



Lesson learned on my part. I have read that the zx12 motor has some head "air caves" where the air likes to sit. I would agree with that from what I experienced.



If I might - a piece of advice: Starting with a cool motor, put it on the Pit Bull, pull the cap start warming it up and add coolant slowly as it warms. Tap lightly on all the hoses (this is important) I got mine to bubble the second time around for about 10 or so minutes. Hope this helps. It would be easier to describe in person.

Don't fall victim to the problem I had... Make sure your radiator cap is clean and seals well<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT=";)">

An air pocket would certainly explain the boiling noises. In a properly purged and pressurized system there shouldn't be any bubbling. I know the YZF's have the same problem, and Blitz's solution is what is prescribed for my bike as well.

If that doesn't work, the radiator cap would be the next suspect.....

back when I had to do the repairs to my radiator I replaced my anti-freeze I had my ratio closer to 50/50 with water. A short ride later it was boiling!! Let it cool down, and rode again, boiling!! I siphoned out some of the mixture and put in more water, test ride and everything was fine. I had heard that the 12 is sensitive to the ratio of anti-freeze and water. I think I am about 35-40% anti-freeze / 60-65% water, and I recently added Redlines water wetter. I have had no problems since.....

answered my own question:



WaterWetter® can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass, and bronze systems.

you are right on subject Ghengis<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT=":)"> Water wetter at about $8 or $9 a bottle is an excellent value. It works great, I use it in my Mustang as well as the 12 now, and you are correct it is an additive to the normal cooling system.......

I've had engine ice in my 12 for a few months now and even drained and refilled once for quality check (the factory original coolant turned into brown slush!) and all is well. I don't think it's the ice. I too tried water wetter and I think the ice is better. My local race shop uses it in their race bikes as well.

Turn's out it was air in the system. I "totally" drained the system and it was

harder to bleed than before. I had to keep tapping on all the line's with the

cap off and the bike running warm. After alot of spilt coolant and tapping,

she's running good again.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/happy.gif ALT=":D"> After idleing for about 15 minute's the temp.

gauge was at 9 o'clock and the fan didn't come on until I shut the bike off.
