Review on Zerostart 3100055 Engine Block Heater: CSA Approved, 120V, 600W for Chrysler, Dodge, Jeep, Kia, Mitsubishi, Hyundai by Michael Moulton

I installed this on a 1995 Grand Cherokee with a 5.2 liter V8 engine. It went in really easily. Honestly being the only tricky part of the installation process was removing the old stub.I use it with an outdoor timer so it's not always on.I set it to turn on 30 minutes before leaving the car. It will not warm up the car to operating temperature but it is not designed for that. On very cold days (below freezing) the car normally takes 30 minutes to warm up. With this product the time is reduced to 5 minutes which is a benefit for my comfort turning point is.
