I had a bit of an accident on my z the other day (rolled down off a hill climb) and now my radiator is slowly leaking. It only leaks when it is pressurized so it cant be that bad. I was wandering if they have special ATV radiator sealant or if i could use automotive sealant. I thought the regular stuff might clog up the water jackets being as the motor is so small compared to a car engine. Any sugestions?

 

If it were mine, I would try to find out where it is leaking and take it to a radiator shop for repair or try to find a used one on ebay. If you add any of that sealant to your radiator, it would just be a temporary fix, and could clog coolant passages in the motor.
