Review on 🔌 Zerostart 3100130 Engine Block Heater for Chevrolet and GMC: V8-6.6L Diesel (Duramax), 2001-2008, 2007-2015 - CSA Approved, 120V, 1000W by Malik Axmed

Well I want to give this one a good thumbs up. but I can not. The first two installed failed within a year. They're pretty hard to replace, so you can imagine how angry I was when I had to replace them. twice. but I think on the good side I've learned to change them. If you can find another brand that lasts longer and has good reviews, I would recommend going that route. These just fail after a year of use.
