Getting Started with Engine Block Heater Removal
Removing an engine block heater is a task that can be tackled with some basic tools and a little know-how. Whether you’re replacing a faulty unit or just want to eliminate it from your vehicle, the process is straightforward. Engine block heaters are typically installed in colder climates to help warm the engine oil and coolant, making it easier to start your vehicle in frigid temperatures. However, if you live in a warmer area or if the heater is malfunctioning, it might be time to take it out.
Tools You’ll Need
Before diving into the removal process, gather the necessary tools. Here’s a quick list:
- Socket set
- Wrench set
- Screwdriver (flathead and Phillips)
- Pliers
- Drain pan
- Shop towels
- Safety goggles
- Gloves
Having the right tools on hand will make the job smoother and prevent unnecessary trips back to the toolbox.
Preparation Steps
Before you start wrenching away, follow these preparatory steps:
1. Safety First
While this isn’t a high-risk job, it’s always smart to wear safety goggles and gloves. You don’t want any coolant splashes in your eyes or skin contact with hot components.
2. Let the Engine Cool
If you’ve recently driven the vehicle, give it time to cool down. Working on a hot engine can lead to burns or other injuries. Patience is key here.
3. Disconnect the Battery
To avoid any electrical mishaps, disconnect the negative terminal of the battery. This is a simple step that can save you from potential shocks or short circuits.
Removal Process
Now that you’re prepped, let’s get into the nitty-gritty of removing the engine block heater.
1. Locate the Engine Block Heater
The engine block heater is usually located on the engine block itself, often near the oil pan or on the side of the block. It will look like a small plug or a cord leading to a heating element.
2. Drain the Coolant
Before you start unscrewing anything, place a drain pan under the engine to catch any coolant that might spill out. Open the radiator cap to allow air in, which will help the coolant drain more smoothly.
3. Disconnect the Heater
Using your socket or wrench, carefully unscrew the heater from the engine block. Be prepared for some coolant to spill out, so keep your shop towels handy. If the heater has electrical connections, make sure to disconnect those as well.
4. Remove the Heater
Once everything is disconnected, you should be able to pull the heater out of the block. If it’s stuck, a gentle twist or wiggle can help loosen it. Avoid using excessive force; you don’t want to damage the engine block.
5. Clean the Area
After removing the heater, take a moment to clean the area around the opening. Check for any debris or old gasket material that may have been left behind. This will ensure a good seal if you decide to install a new heater or plug the hole.
Final Steps
With the heater out, you have a couple of options. If you’re replacing it, simply reverse the removal steps with the new unit. If you’re not installing a new heater, make sure to plug the hole with a proper freeze plug or a similar component to prevent leaks.
1. Refill Coolant
If you drained coolant, now’s the time to refill it. Use the manufacturer-recommended coolant and follow the proper filling procedure to avoid air pockets.
2. Reconnect the Battery
Once everything is back in place and you’ve double-checked your work, reconnect the negative terminal of the battery.
3. Test the System
Start the engine and let it run for a few minutes. Check for any leaks around the area where the heater was removed. If everything looks good, you’re all set.
Removing an engine block heater isn’t rocket science, but it does require attention to detail and a bit of mechanical know-how. With the right tools and steps, you can tackle this job efficiently.

Locating the Engine Block Heater
The engine block heater is typically found on the engine block, often near the oil pan or on the side of the block. It may look like a small plug or have a cord leading to it. Identifying its location is the first step to removal.
Draining the Coolant
Before you start unscrewing the heater, you need to drain the coolant to prevent spills. Here’s how:
- Place a drain pan under the radiator to catch the coolant.
- Open the radiator cap to allow air in, which will help the coolant drain more smoothly.
- Locate the drain valve on the radiator and open it to let the coolant flow into the pan.
Disconnecting the Heater
Once the coolant is drained, you can proceed to disconnect the engine block heater:
- Using your socket or wrench, carefully unscrew the heater from the engine block. Expect some residual coolant to spill out.
- If the heater has electrical connections, disconnect them carefully to avoid damaging the wires.
Removing the Heater
With the heater disconnected, it’s time to remove it:
- Gently pull the heater out of the block. If it’s stuck, a slight twist or wiggle can help.
- Avoid using excessive force to prevent damaging the engine block.
Cleaning the Area
After the heater is removed, take a moment to clean the area around the opening:
- Inspect for any debris or old gasket material that may have been left behind.
- Use shop towels to wipe down the area, ensuring a clean surface for any new installation.
Final Steps
Depending on your plans, you may want to install a new heater or simply plug the hole. If you’re installing a new heater, follow the manufacturer’s instructions for installation. If you’re plugging the hole, here’s what to do:
- Insert a new freeze plug into the opening, ensuring a snug fit.
- Use a hammer to tap it in place gently, if necessary.
Refilling Coolant
If you drained the coolant, it’s time to refill it:
- Use the manufacturer-recommended coolant.
- Follow the proper filling procedure to avoid air pockets in the system.
Reconnecting the Battery
Once everything is back in place, reconnect the negative terminal of the battery. This is a simple step that ensures your vehicle is ready to go.
Testing the System
Finally, start the engine and let it run for a few minutes. Check for any leaks around the area where the heater was removed. If everything looks good, you’re all set.
Common Issues and Troubleshooting
While removing an engine block heater is generally straightforward, you may encounter some common issues. Here’s a table to help you troubleshoot:
