Mishimoto Liquid Chill Stop Leak is an 8 oz. emergency coolant sealant formulated to stop small leaks in radiators, fittings, and engine blocks. Independently lab tested, it seals holes up to 0.6mm and cracks up to 0.25mm by 12mm without clogging passages, using microfibers and copper particles that build a cured seal when exposed to heat. Compatible with all coolant types, it can be left in the system or flushed at the next coolant change.
