Description

Disaster rarely strikes at opportune moments when you have all the tools and resources to overcome it. Radiators crack at the track just after the last parts store closes. You got the last fitting they had but went one rotation too far and righty-tighty became righty-loosey. Rent, the electric bill, and that cracked block came due on the same day. It's Sunday night, 10-degrees outside, there's a puddle of coolant under your car, and you just need to get to work tomorrow. Sometimes, being an enthusiast means learning how to pivot and do what's necessary to get home. For those times, Mishimoto is here with our tested and proven Liquid Chill Stop Leak by K-Seal.----This stop leak has been independently lab tested and proven to seal holes up 0.6mm in diameter and cracks 0.25mm wide by 12mm long, without clogging your radiator or engine coolant passages. The key to this ability is its special blend of microfibers and copper particles that are small enough to flow freely through the cooling system. When pushed through a hole or crack, those particles and microfibers begin to build a wall that seals the leak. Heat and exposure to atmosphere or combustion gasses then cure the sealant for a permanent fix.----The best part of our stop leak is its simplicity. Simply shake the bottle, add it to the cooling system, and run the engine. Liquid Chill Stop Leak is compatible with all coolant types and doesn't require any special preparation. Liquid Chill Stop Leak provides a permanent seal without clogging cooling passages, so it can be left in the system or flushed with your next coolant change. So, if you're in a pinch, or are just tired of hunting for a solution to your coolant leak, look no further than Mishimoto's Liquid Chill Stop Leak.
