Engine Block Heater

Reliable Engine Block Heaters

An engine block heater is the simplest, most effective way to ensure your engine starts smoothly in cold weather. It warms the engine block and coolant before ignition, helping fuel ignite efficiently, protecting your battery, and reducing wear on vital engine parts.

At FridayParts, we stock a full range of engine block heaters for agricultural, construction, and heavy‑duty machines from brands like Cummins, Kubota, John Deere, Ford, Dodge Ram, Caterpillar, and more. Every heater is tested for leak‑free fit, accurate wattage, and durable construction, so your engine performs reliably even on the coldest mornings.

Main benefits include:

• Easier cold‑weather starts
• Reduced battery and starter strain
• Improved engine performance and longevity
• Helps improve fluid circulation by warming the engine block and internal fluids.
