Anybody know of Any downside of using water with Water Wetter versus coolant solution? This would be only for track season. I would put coolant back in over winter.
Thanks

Check part # of tank cap. If the part # doesn't end in '02' or '04' ('03' was skipped for some reason), or some higher number now replace it with a new cap.

A sudden loss of even an engine cooling system filled with water wetter could have you end up on a guard rail or send another driver off into the weeds avoiding you.
Even if you and others manage to keep things on the asphalt a hard running engine should not experience a catastrophic loss of coolant if it can be avoided. The engine has a considerable heat load that has suddenly no where to go with the loss of coolant concurrent with a loss of pressure.
That very hot coolant will flash to steam and what coolant remains and can flow through the engine will be blocked at some places at least partially and localized overheating will result.
Serious engine damage can arise from this.
An engine (with fresh oil) and with a properly functioning cooling system -- this means one that is not only fluid tight but pressure tight -- with both fans working and clean trash free radiator ducts should be able to handle anything you throw at it track-wise.
Sincerely,
Macster.

z99, you can read some test that say that when you increase the water ratio, and less coolant you can actually get a "little" more cooling/heat transfer. From what I have seen 60/40 vs 50/50..
