Introduction And Types Of Block Heater

The block heater is an ingenious and invaluable piece of automotive technology that allows your car to drive and start more reliably at low temperatures. The block heater warms the vehicle's engine and engine fluids. 

It allows the engine oil to circulate through the engine more efficiently. The end result is less waiting for the engine to reach its optimal operating temperature. You can look at car engine block heater via

The block heater consists of two main components – a heating element and a power cable. The heating element is installed in the engine block openings (the part of the engine containing the cylinder, among others). The heating element supplies heat to the motor, which is routed through a wire.

Types of block heaters and their devices

Before deciding on block heating, you need to know the different types of block heating. There are five types you will need to switch to: internal heater, freezer heater, cartridge heater, drain plug heater and oil pan heater. Let's briefly summarize each of the types of block heaters and the process of their installation.

Internal heating

Internal heating is the most traditional way of delivering heat to your car's engine, and it is also one of the most reliable types of block heaters. Internal heating functionality is simple but very efficient. The liquid circulating through the cooling hose flows through the newly installed heater.

Installation steps

  1. Cut the cooling hose in half with the antenna section

  2. Take the block heater's inlet port and connect it to one end of the freshly cut hose

  3. Take the output connector from the block heater and plug it into the other end of the freshly cut hose
