Brand and compatibility guide
Zerostart / Phillips & Temro Block Heaters
How Zerostart block heaters, cords, magnetic heaters and circulation heaters fit together—and how to search the part numbers used in Canadian applications.
Our verdict
The best starting brand when you need an engine-specific heater or replacement cord. Its application catalog covers an unusually broad mix of cars, trucks, diesels and equipment.
Known for
- ✓ OEM-style frost-plug and cartridge heaters
- ✓ Heavy-duty threaded and plate heaters
- ✓ Replacement and illuminated cordsets
- ✓ Magnetic, circulation and battery heaters
Before you buy
- — Match the engine, year and displacement—not only the vehicle badge.
- — A 31/35-prefix generally identifies a heater kit; 36-prefix numbers are commonly cordsets.
- — Compare the connector on an old cord before ordering a replacement.
- — Never substitute a 240 V element for a Canadian 120 V driveway outlet.
