Not to throw the GT3 guys under the bus, but I can't remember a club race or DE when at least one run session over the weekend wasn't affected by a GT3 spewing coolant (without mentioning any names, one particular car leaked coolant on track on at least 4 different occasions last season alone).

There is a well documented defect in the GT3 coolant system (glued fittings and crappy engineering on the collant manifold). Here's a thread from rennlist with more than 90 posts with an attempt to create a registry of GT3 owners who have experienced coolant system failures mostly while on track, and many of which were catastrophic failures. All of the guys that I know that own GT3s have had it happen (perhaps Terry, Kenny, or Graham can chime in on their experiences). I think we've just been lucky that none have (yet) resulted in serious injury.

Perhaps even changing our tech form is warranted to include a line item about what type of coolant is in the car and a written "recommendation" that water be used in stead of antifreeze while on track. Also would provide an opportunity during tech for the inspector to discuss the issue with the owner.

I don't frequent the forums, so just ran across this thread.

FWIW, I have not had a coolant failure in my car (I am one of the GT3-guilty). Perhaps it will happen.

I have considered changing over to water, but have not done so since i was concerned about water pump failure, corrosion, etc, etc. There are pros and cons to everything.

I am curious about this Evans stuff: how slippery is it. Seems to be used in some racing applications but has many of the positive properties of AF.

As far as the tech form idea, that is a very sensible.
