Cracking the Code: What is the Plug on the Front of My Truck?

Published by Dustin Babich on

The plug on the front of your truck is likely a block heater, which helps warm up the engine in cold weather. As temperatures drop below freezing, the fluids in your vehicle become thicker and harder for the engine to circulate.

This can make it difficult for your truck to start or even cause damage to the engine. The block heater serves as a preheater, heating up the coolant and oil in the engine which makes cold-weather starts easier and quicker.

It also reduces engine wear and tear and improves fuel efficiency. The plug is usually located near the front bumper or on the grille, and can be plugged into a standard electrical outlet with an extension cord. Invest in a block heater and say goodbye to endless attempts to start a stubborn truck during freezing temperatures.
