Buying Guide for Aftermarket Block Heaters
When selecting an aftermarket block heater, consider the following key factors to choose the best option for your needs:
Compatibility
Check your vehicle or equipment’s engine model and part number requirements. Some heaters are designed for specific models (e.g., 1160, 1155 series) or brands, while others offer universal magnetic attachment for flexible use.
Power Rating
Block heaters come in various wattages, typically ranging from 200 watts to 1000 watts. Higher wattage heaters warm the engine faster but consume more electricity. Balance your engine size and typical cold climate needs to select appropriate power.
Installation Type
- Magnetic heaters attach externally without modifications and are easy to install.
- Frost plug/heater kit style requires installation inside the engine block and usually provides more efficient heating.
- Cord replacements ensure your heater maintains function and are vital to consider for maintenance.
Safety Features
Look for heaters with built-in thermostats or temperature control to avoid overheating, electrical shorts, or damage to your engine and heater components.
Durability and Build Quality
Choose products from reputable brands or those meeting certification standards for long-term reliability, especially in extreme winter conditions.
Purpose and Usage
Consider if you need an all-season solution for different equipment types or if a model-specific heater is more suitable. Versatile magnetic heaters offer multi-device use, whereas specialized frost plug heaters provide optimized heating for a designated engine.
