2017 Honda CR-V Coolant Capacity & Type

The 2017 Honda CR-V has a total cooling system capacity of between 6.2 and 7.3 quarts (5.9 to 6.9 liters), depending on the engine option.

Quick Answer

• Total Capacity (1.5L Turbo): 6.2 quarts (5.9 liters)
• Total Capacity (2.4L): 7.3 quarts (6.9 liters)
• OEM Coolant Spec: Honda Long Life Antifreeze/Coolant Type 2
• Coolant Color: Blue
• Coolant Chemistry: Phosphate-free, Silicate-free HOAT (Hybrid Organic Acid Technology)
• Mix Ratio: 50/50 Pre-mixed

Capacity by Engine Option

The 2017 model year was a transition year for the CR-V, offering two different four-cylinder engines. The cooling system capacity varies slightly between them. These figures include the engine, radiator, and coolant reservoir.

It is critical to use the correct coolant—Honda Type 2—which is sold pre-mixed and should not be diluted further with water.

Flush Interval

Honda vehicles use a "Maintenance Minder" system that displays codes on the dashboard to alert the driver when service is needed. A coolant flush is typically indicated by sub-item "5" (e.g., "B15").

• Normal Service: The initial coolant flush is recommended at approximately 10 years or 100,000-120,000 miles.
• Subsequent Service: After the initial flush, the interval shortens to every 5 years or 50,000-60,000 miles.
• Severe Duty: If you operate your CR-V in extreme heat, mountainous terrain, or primarily for short trips, the Maintenance Minder may recommend a flush sooner. There is no separate "severe" schedule to follow; simply adhere to the vehicle's onboard monitoring system.

How to Refill & Bleed

Air pockets trapped in the cooling system after a drain and refill can cause engine overheating and heater performance issues. The 2017 CR-V does not have a dedicated air-bleed screw, making the process slightly more technique-dependent.

1. Ensure the engine is completely cool and the vehicle is parked on a level surface.
2. Place a drain pan under the radiator and loosen the petcock at the bottom to drain the system. Remove the radiator cap to speed this up.
3. Once drained, tighten the petcock.
4. Place a large, spill-proof funnel into the radiator neck. This type of funnel is essential for properly bleeding the air from a modern Honda system.
5. Slowly pour Honda Type 2 coolant into the funnel until it is about half-full and the radiator is full.
6. Start the engine and turn the cabin heater on to the highest temperature setting with the fan on low.
7. As the engine warms up, the thermostat will open, and you will see the coolant level in the funnel drop as it circulates through the system. You will also see air bubbles coming up into the funnel.
8. Continue adding coolant to the funnel as needed, keeping it partially full. Let the engine run until the radiator fan cycles on and off at least twice and the bubbling has stopped.
9. Squeeze the upper and lower radiator hoses occasionally to help dislodge any trapped air pockets.
10. Once the air is bled, shut off the engine. Let it cool completely before removing the funnel and reinstalling the radiator cap.
11. Top off the plastic overflow reservoir to the "MAX" line.

For professional shops, using a vacuum-fill tool is the fastest and most effective method to prevent air pockets.

Common Cooling System Issues

The fifth-generation CR-V (2017-2022) has a generally reliable cooling system, but there are a few notable points:

• Oil Dilution (1.5L Turbo): The most discussed issue with this generation is fuel (oil) dilution, where gasoline makes its way into the engine oil. This is most common in cold climates during short trips where the engine doesn't reach full operating temperature. While not a direct cooling system fault, a properly functioning thermostat and cooling system are critical for allowing the engine to warm up quickly to mitigate this issue. Honda has issued software updates to address this.
• Component Wear: Like any vehicle, the water pump, thermostat, radiator, and hoses are subject to wear over time. Leaks are not widespread but can occur as the vehicle ages. Using the incorrect type of coolant (e.g., a universal green or orange coolant) can accelerate the degradation of seals and gaskets, leading to premature leaks and potential blockages.

Always use the specified blue Honda Type 2 coolant to ensure the long-term health of your vehicle's engine.
