Review on 🔌 Zerostart Engine Block Heater 310-0015 by Phillips & Temro by John Kennedy

I was very happy to find this, not so much that I couldn't install it. The instructions recommended professional installation for my van. I figured it was because opening a freeze plug is a really big deal. But you can't get to the freezer plug in my van without thorough disassembly. I had to return it for a tank unit.
