2020 Honda CR-V Coolant Capacity & Type

The 2020 Honda CR-V holds approximately 6.94 quarts (6.57 liters) of coolant in its cooling system.

Quick Answer

• Total Cooling System Capacity: 6.94 quarts (6.57 liters)
• OEM Coolant Spec: Honda Long-Life Antifreeze/Coolant Type 2 (Blue, OAT - Organic Acid Technology)
• Mix Ratio: 50/50 Pre-mixed (do not add water)

Capacity by Engine Option

The 2020 Honda CR-V primarily came with one engine option in most markets, the 1.5L VTEC Turbo engine.

Note: The hybrid model has a separate inverter cooling system with a different, smaller capacity. This article focuses on the engine cooling system.

Flush Interval

Maintaining your coolant flush interval is crucial for the longevity of your cooling system components and overall engine health. Honda recommends the following:

• Normal Duty: Replace initially at 120,000 miles (192,000 km) or 10 years, then every 60,000 miles (96,000 km) or 5 years thereafter.
• Severe Duty: If you operate your CR-V under severe conditions (e.g., frequent towing, extreme temperatures, mountainous terrain, or heavy city driving), it's wise to consider shortening these intervals by about 25-50% for optimal protection.

How to Refill & Bleed

Properly refilling and bleeding your 2020 Honda CR-V's cooling system is essential to prevent air pockets, which can lead to overheating. Always perform this procedure on a cool engine.

1. Drain: With the engine cool, open the drain plug on the bottom of the radiator and remove the radiator cap to allow the system to drain completely. Some models may have a drain plug on the engine block as well. Consult your service manual.
2. Close Drain & Flush (Optional): Once drained, close the radiator drain plug. If performing a flush, refill with distilled water, run the engine with the heater on until warm, then drain again. Repeat until the drained water runs clear. Skip this step if only topping off or replacing without a full flush.
3. Refill: Close all drain plugs. Slowly fill the radiator with the Honda Long-Life Antifreeze/Coolant Type 2 (50/50 pre-mixed). Fill the reservoir to the MAX line.
4. Bleed Air: Leave the radiator cap off. Start the engine and let it run until it reaches operating temperature (the cooling fan cycles on). Once hot, turn your heater to its highest setting (full hot and high fan speed) to open the heater core valve and circulate coolant through the heater core. This helps purge air.
5. Burping: Gently squeeze the upper and lower radiator hoses several times to help dislodge air bubbles. You should see bubbles rising in the radiator neck.
6. Maintain Level: As the engine warms and air purges, the coolant level in the radiator will drop. Continuously top off with coolant to keep it full.
7. Final Steps: Once no more bubbles appear and the cooling fan has cycled a few times, install the radiator cap. Check the coolant level in the reservoir after a test drive once the engine is cool. Top off as needed.

Pro Tip: Some technicians find using a vacuum fill tool highly effective for bleeding Honda cooling systems quickly and completely, eliminating air pockets. There are no specific bleed screws on the 2020 CR-V's 1.5L engine cooling system; the bleeding process relies on cycling the engine and heater.

Common Cooling System Issues

While generally reliable, the 2020 Honda CR-V (and the 5th generation CR-V in general) can experience a few cooling system-related issues:

• Coolant Leaks: Leaks can occur from hoses, the radiator, water pump, or thermostat housing. Keep an eye out for blue or green puddles under your vehicle. The 1.5L turbo engine, due to its complexity, has more potential leak points than older, simpler engines.
• Thermostat Failure: A failing thermostat can cause the engine to overheat (stuck closed) or run cooler than optimal (stuck open). Symptoms include fluctuating temperature gauges or slow engine warm-up.
• Water Pump Issues: Although less common on newer models, water pump bearings or seals can eventually fail, leading to leaks or noise. A failing water pump can also cause overheating if it's not circulating coolant effectively.
• Radiator Fan Problems: The electric cooling fans can fail, leading to overheating, especially in stop-and-go traffic or at idle. Listen for the fans engaging when the engine is hot.
• Head Gasket (Less Common): While not a widespread issue for the 2020 CR-V, any engine can develop a head gasket leak, which can allow coolant to enter the combustion chambers or exhaust, or exhaust gases to enter the cooling system, leading to overheating and coolant consumption.

Regular inspection of hoses, clamps, and coolant levels, along with adhering to the recommended flush intervals, will help prevent most cooling system problems.
