When operating off-road vehicles during winter, the harsh conditions can take a toll on your machinery’s performance. The biting cold can make starting your diesel engine a challenge, not to mention the increased stress and wear on the components. At FridayParts, we’re no strangers to the extra care off-road equipment requires in the winter. That’s why we’re here to guide you through the importance of using a block heater on your diesel engine and the best practices for doing so.
For those who work on construction sites, manage farms, or engage in any outdoor winter operations, your off-road vehicles are the backbone of your productivity. The last thing you need is a machine that refuses to start or performs poorly in the cold. Just like us, these engines don’t fare well in freezing temperatures, but unlike us, they can’t simply warm up with a hot cup of coffee. That’s where a block heater comes in – a simple yet effective solution to keep your diesel engines running smoothly through the winter. In this blog, we’ll explore what is an engine block heater, when to use a block heater in a diesel, and offer a step-by-step block heater replacement guide. So, let’s dive into the world of block heaters and keep your machinery rolling, even when the temperatures are not.
What is an engine block heater?
An engine block heater is also known as a glow plug warmer. It is a device that warms up the coolant in your engine before starting. As the thick engine oil becomes more viscous at lower temperatures, it can be more challenging to start diesel engines due to their higher compression ratios. That is when the block heater plays its magic. The block heater serves typically as an electric unit that plugs into a standard electrical outlet and warms the engine block, which in turn heats the engine’s coolant.

How does a block heater work?
A block heater contains a heating element that warms the engine’s coolant when plugged in. The heated coolant then circulates through the engine block, warming it up and making it easier to start the engine in cold conditions. This process can significantly reduce the strain on the engine, reducing the risk of starting issues and extending the engine’s lifespan.
When to use a block heater?
Many people think of a diesel engine block heater as a tool that is only useful when in frigid weather, or when the engine is unable to start without it. But in fact, most diesel manufacturers recommend using the engine block heater whenever you plan to start the rig at temperatures of 20°F or lower. Here are some scenarios where a block heater should be used provided by FridayParts for your reference:
- Daily Use in Winter: If you use your off-road vehicle daily during the winter, a block heater can reduce the stress on the engine and improve its performance.
- Temperatures Below Freezing or Extreme Cold: If the temperature is expected to drop below freezing, especially for extended periods, a block heater can help prevent the engine from icing up and ensure a smoother start.
- Long Idle Periods: If your off-road vehicle is going to be parked for an extended period in cold weather, using a block heater can prevent the engine from cooling down too much, which can cause starting issues.
- Before a Long-term Use: The engine will take longer to start after extended periods of inactivity even in moderately cold conditions, causing additional wear on internal components before the oil begins to fully circulate. This can also do damage to your battery and starter motor. So, for example, if you’re going to spend some time driving your equipment for a long period of time where the average temperature is below 50°F, FridayParts recommends you turn on your engine block heater the night before you plan to drive.
How to Install a Block Heater？
Feeling like DIY? Installing a block heater is a relatively straightforward process. By taking the following steps, you can ensure your off-road diesel engine is well-prepared for the winter months.
1. Gather Tools and Equipment
To get started, you will need more than just a performance engine block heater. Round up a wrench, a screwdriver for any stubborn parts, and zip ties to keep your power cord in check. And of course, make sure you’ve got access to a wall outlet for the grand test drive after installation.
2. Locate the Freeze Plug on the Engine Block
Now, it’s time to get up close and personal with your engine. Find that freeze plug on the engine block; it’s the spot where your block heater is about to make itself at home.
3. Remove the Freeze Plug
With your wrench in hand, carefully unscrew and remove the freeze plug. This step might need a bit of elbow room, so clear away any parts that are getting in the way.
4. Install the Block Heater:
Slide the block heater into the now-empty freeze plug hole. Make sure it’s sitting pretty and not causing any engine drama with its neighbors.
5. Attach the Power Cord:
Hook up the power cord to your new block heater and guide it along a path of least resistance, avoiding any dance-offs with other engine parts. Use those zip ties to keep the cord neat and tidy along a lower engine line, where it’s out of harm’s way but still within reach.
6. Test the Installation:
Now for the moment of truth. Plug your heater into a wall outlet and set the timer for about 30 minutes to two hours. This gives the heater enough time to warm up the engine and show off its stuff.
7. Check for Temperature Increase:
After the heater has had its time in the spotlight, you should feel a noticeable warm-up in the engine’s temperature. This is your green light that your block heater is working like a champ.
And there you have it—a step-by-step guide to installing a block heater on your off-road diesel engine. With this winter-ready setup, you’ll be powering through the cold with ease.
