Do subarus have engine block heaters?
Yes. Many Subarus sold in cold-weather markets include an engine block heater as standard equipment or as a factory/dealer-installed option. In the United States, it is not universal across all models, but it is commonly available on several trims or via cold-weather packages, and in Canada and other northern markets it is frequently included.
Engine block heaters preheat the engine by warming the coolant in the engine block, which makes starting in cold conditions easier and reduces wear on startup. They typically use a standard 120-volt outlet and are designed to be plugged in for several hours before starting the car. If your vehicle does not have one, it can often be added by a dealer or via an approved aftermarket kit; always verify compatibility with your model and warranty.
Regional availability and model variations
Block heater availability for Subarus varies by market, model, and trim. The following outlines common patterns you may encounter.
Model-year and trim considerations
- Canada: Block heaters are commonly included or readily available as part of winter packages on many models.
- United States: Not universal across all models; some trims or packages include a block heater, while others do not. Dealer-installed options or aftermarket kits are common paths for installation.
- Other markets: Availability depends on local climate, model, and regulations; check with a local Subaru dealer for the exact specification on your vehicle.
- Additional preheating options: Some models offer remote start or integrated preheating features that can complement or substitute for a dedicated block heater.
Region and model details matter. For a precise answer about your exact car, consult your dealer or check the vehicle’s documentation for the block heater specification.
How to check if your Subaru has one and how to use it
Use these steps to verify presence and plan installation if needed.
Steps to verify and plan installation
- Consult the owner's manual for an entry labeled “Engine Block Heater” or “Block Heater.”
- Look for a 120V exterior plug inlet near the front bumper or grille area, sometimes behind a small door or protective cover.
- Inspect the engine bay for a block heater element or a label indicating a heater in the coolant system.
- Use the vehicle’s VIN with a Subaru dealer or official site to confirm whether a block heater was factory-installed for your specific model/year.
- If not installed, ask the dealer about factory-installed options or approved aftermarket block heater kits compatible with your engine and warranty.
If you decide to add one, have it installed by a qualified technician and ensure the installation uses an outdoor-rated cord and proper electrical protections to maintain safety and warranty validity.
Usage tips and safety
Practical guidance to get the most from a block heater while staying safe.
Safe usage guidelines
- Plug into a weatherproof, outdoor-rated extension cord. Use a timer or smart plug to preheat at a scheduled time.
- In very cold weather, preheat to several hours (often 2–4 hours or overnight) before starting the engine for optimal warmth and easier starting.
- Keep the extension cord away from moving parts, hot surfaces, and standing water; avoid running cords through doors or windows.
- Ensure the vehicle’s battery is in good condition; a healthy battery improves cold-start reliability even with a block heater.
- After starting the engine, you can idle briefly or drive gently to allow the engine to reach normal operating temperature; unplug the block heater once the engine is warm.
Block heaters are a simple, effective way to reduce cold-start wear, but always follow manufacturer recommendations and use proper outdoor-rated equipment for safety and warranty considerations.
Summary
Engine block heaters are common in Subaru models sold in cold climates, but availability varies by market, model, and trim. Canada and many northern markets frequently include them, while the United States often offers them as an option or aftermarket installation. To confirm for your vehicle, check the owner’s manual, inspect for an exterior 120V plug, and consult with your local Subaru dealer using your VIN. When used correctly—with a proper outdoor extension and a timer—block heaters can improve cold-start reliability and reduce engine wear during winter driving.
