Reduce stress to your engine, battery, starter motor and more
Starting an engine when it’s severely cold stresses your engine. When it’s cold, your oil gets thick, resulting in a couple of negative side effects. In Medicine hat, we know all about cold weather!
First, thicker oil increases the amount of work required by the starter to turn the crank engine. That creates longer starting times. Second, when oil is too thick, it can’t shoot through all the engine’s channels to lubricate critical components. The result is when your engine starts, those parts scrape against each other without any lubrication. Plus, if the engine’s running with cold parts that haven’t been able to warm and expand to the right size, they can get damaged.
Starting is harder for the engine and it really wears out your parts, and not just your engine, but your battery and your starter motor too.
Warm up your cabin more quickly
Those first few seconds inside a cold vehicle can be just as painful for you as they are for your vehicle. With engine coolant fluid that’s been warmed by the block heater, your cabin can draw in warm air almost immediately after you start it in the morning.
Your block heater only needs four hours to warm your engine before you start it.
