Review on Zerostart 3100072 Freeze Diameter Approved by Marquel Henry

In current weather with temperatures in the single digits or below zero degrees Fahrenheit, I've used an oil pan heater that sticks to the pan with a magnet. It was becoming a chore to crawl under the car every night to turn on the heater, so I bought and installed this engine block heater. Installation was surprisingly easy. The biggest challenge was flushing and filling the cooling system. The actual installation of the heater was fairly easy. All I had to do was remove the air filter housing on my Jeep and was able to access the freeze plug to install the heater. I put the heater on a timer so my car warms up about three hours in the morning before I have to leave. Starts immediately, engine warmed up after a few minutes. If you are interested in car repairs, this heater is a good choice.
