Review on ❄️ Zerostart 310-0005 Engine Block Heater: Superior Cold Weather Performance by Andy Baker

Installed block heater in December 2017 on my wife's 2003 Chevrolet Z71 Suburban 180k. The installation took about 40 minutes in total. No more long waits or exhausting idles on those terribly cold mornings. It's nice to feel the warmth of the ventilation so soon. I really believe this will extend the life of the car's engine and I wish I had done it sooner.
