Review on 🔧 Efficient OTC 6046 Heater Line Quick-Connect Release Tool for GM: Simplify Your GM Heater Line Maintenance! by Mark Colbert

This little tool is a life saver. I used it on my 2005 Chevy Silverado 2500HD LS with a 6.0 petrol engine. It fits both heater hose adapters and I removed them both within 15 minutes. The hardest part is sliding them backwards, but once they go in I twisted the heater hose adapters and they slide right off. I turned about 1/4" left and 1/4" right and they both just slid out. Highly recommended
