Well that is surprising for sure....... I'm not sure what that's about but I've been using Engine Ice ever since I changed the magnesium engine cover over to aluminum back when my z400 was only a few months old.......

At the time, everyone was saying to stay away from any 50/50 mix of water and traditional antifreeze and someone recommended Engine Ice to me. That was back in 2006 I believe and I've not had any problems yet...... and it gets very cold here in NY, well below 10F....We usually get at least a few sub-zero days every year......

One of the benefits of Engine Ice too is that it is so much lighter compared to antifreeze, it puts less strain on the water pump.....But any high performance coolant will do the same.

I wonder if perhaps this person did not flush their system totally before putting in the Ice. Because if there was some water left in there as it will pool in the lower areas, that would raise the freeze temp a lot....... I have not stuck a hydrometer into mine to test it, but I can. I'm pretty sure Engine Ice would not be lying about that because they would not have many customers after the first 1000 engines were ruined after freezing......

 

Well I just got some 50/50. ss97, why were people saying stay away from 50/50? I called one of my larger local dealers and they said its (50/50) all they use.

 

If you want the benefit of max cooling, just run water in the summer, or at least a heavier water to coolant mix

 

All done! Not a single problem.

Always a good feeling.

 

OK, I installed the thermal switch this past weekend and went riding on Saturday. It was pretty darned hot too. I think I noticed that the fan was coming on more often, but the butt dyno didn't show any improvement in power (that I could notice).

Although this was only a $20 mod, removing the filter lid and rejetting the main with a 155 or 160 Mikuni is still the best bang for the buck mod.

 

Well thanks for checking it out! Can't say I'm terribly surprised by your result though.
