Review on 🔌 Zerostart 3100002 Engine Block Heater: Ford, Jaguar, Mazda, Lincoln, Volvo - CSA Approved, 120V, 400W by Elmito Yeager

I bought this for Mazda 3 2004 2.3L. Installation was a headache, mostly because I couldn't find any information on where the port was. So it took some work. However, once he found it, installation was a breeze. Threads are wrapped in protectant/sealant, eliminating the need for tape or elbows. I use it with a timer and so far if it's turned on an hour before driving it takes about five minutes for the engine to warm up (ie drive). If you can pay more than $350 a ton and don't want to, winterize your car as long as it looks like a good product.
