Review on 💦 Lisle 60900 Heater Core Backflush Tool: Efficient Solution for Flushing Heater Cores by Bill Tripi

This product saved me a lot. I got a $4500 offer to fix a blown head gasket and water pump so I decided to replace my own water pump and just ran about $30 of K&W through the engine to fix the leaks and try to stop the repair seal. It worked, but at the same time it clogged my heater core and my engine ran very hot and I had to keep adding coolant. I tried a cheaper garden hose flushing tool but it didn't work because the water flushed in two different directions instead of straight into the clog. I flushed it and my car has been running fantastic for a few months now and no longer need to add coolant!
