Engine Block Heaters for Diesel Engines and Cold-Weather Starting

Find engine block heater replacement parts for selected diesel engines, trucks, tractors, and industrial equipment at Fab Heavy Parts. This engine block heater collection includes electric engine block heater elements, heater kits with power cords, and selected engine preheaters for different applications.

An engine block heater warms the engine or coolant before startup, helping reduce the challenges associated with starting equipment in cold temperatures. Different heater designs use different installation methods and electrical specifications, so choosing a suitable replacement requires more than matching the engine brand.

Engine Block Heaters for Trucks, Tractors, and Equipment

Our selection includes replacement block heaters listed for selected Ford Powerstroke, Cummins, John Deere, Kubota, Massey Ferguson, and other engine applications.

Examples include replacement engine block heater elements for selected Ford 7.3L Powerstroke diesel trucks and vans, 750W replacement heaters for specified Cummins 5.9L and 6.7L applications, and 400W replacement heaters listed for selected John Deere and Kubota tractors.

The engine block heater collection also includes replacement heater options for Massey Ferguson and Perkins agricultural equipment, along with an industrial engine preheater listing.

Each product has its own application requirements. A heater listed for one engine family should not be assumed compatible with every engine or equipment configuration within that family.

Understanding Engine Block Heater Types and Specifications

Available engine heating products differ in their heating method, mounting arrangement, and electrical requirements.

Threaded heater elements are identified by specifications such as thread size, voltage, and wattage. Some replacement kits include an electrical cord, while others may require additional components.

Industrial preheaters can use different operating voltages and control arrangements from conventional engine-mounted heating elements.

Before purchasing, compare the existing heater's part number, installation interface, electrical rating, and supplied components with the information provided on the replacement product page.

How to Choose the Right Replacement Engine Block Heater

Start with the existing heater's part number or your engine manufacturer's parts documentation. Confirm the engine model, equipment application, and serial number where relevant.

Check whether the replacement uses the correct mounting configuration and electrical supply. Do not substitute a heater with a different voltage, wattage, or connection type without confirmation from the appropriate service documentation.

For more information about cold-weather engine preparation, read our engine block heater guide. You can also explore related engine water pumps and thermostat replacement parts when inspecting associated cooling-system components.

Review the individual product specifications before ordering to identify an appropriate replacement for your engine.

Frequently Asked Questions

How do I know which engine block heater fits my engine?

Start by checking the part number on your existing heater or in your engine's parts manual. Then compare the engine model, equipment application, mounting configuration, and electrical specifications with the engine block heater listing. If the part number is unavailable, the engine serial number and photos of the original heater may help identify the correct replacement.

Can I replace my 400W engine block heater with a 750W or 1000W heater?

Not without confirming compatibility. Wattage affects the heater's electrical and thermal requirements, while voltage and mounting design must also match the intended application. We recommend using the specifications approved for your engine rather than selecting a higher-wattage heater simply because it produces more heat.

Does an engine block heater come with the power cord?

It depends on the product. Some of our engine block heater listings specify that a power cord is included, while others describe the heating element or a different type of preheater. Please check the individual product description and included components before ordering.

What should I check before installing my replacement engine block heater?

Before installation, confirm the part number, mounting interface, voltage, wattage, and any required seals or electrical connections. Follow the engine manufacturer's installation instructions. Electrical power must be disconnected during installation, and coolant-related work should only be performed when the engine has cooled sufficiently.

What should I do if my engine block heater does not warm the engine?

First, stop using the heater if the cord, plug, or connections show damage. Have the electrical supply, heater connection, and heating element checked according to the equipment manufacturer's diagnostic instructions. A faulty power source, damaged cord, incompatible heater, or failed element may prevent proper heating. Do not continue using a heater that shows signs of electrical damage or overheating.
