Benefits of a Heated Engine
Start your engine easier and warm your cab faster in cold weather with this cartridge-style engine block heater. Heating your engine coolant keeps it from thickening and freezing, resulting in more reliable start-ups and smoother operation altogether. It also lessens the workload and extends the life of your vehicle's battery. And because starting your engine when it's warm creates less condensation in the engine block than starting it when it's cold, your engine will get better initial fuel vaporization, which causes fewer emissions and less pollution.
Cartridge-Style Heater
This cartridge-style heater simply clips into the cavity of your engine block. There is no need to remove the core frost plug. The power cord on the heater is removable so that you won't need to buy a whole new heater if the cord gets damaged. The cord can be routed through your grille for easy access to a 120-volt outlet or extension cord. Make sure the heating element is fully submerged in the coolant before plugging it in.

Install was super easy, product works great exactly as expected. Since installing we have not had the same temps that I ordered it for but sure does allow the engine to crank effortlessly.

-29 sounds a true test of durability, that's insanely cold! We recently had a few days below zero but nothing like what you get it sounds like. Stay warm Paul!
