2018 Toyota Camry Coolant Capacity & Type

The 2018 Toyota Camry's cooling system holds approximately 6.9 to 7.4 quarts (6.5 to 7.0 liters) of coolant, depending on the engine. This article provides a comprehensive guide to your 2018 Toyota Camry's coolant needs.

Quick Answer

• Total Cooling System Capacity:
  • 2.5L 4-cylinder engine: Approximately 6.9 quarts (6.5 liters)
  • 3.5L V6 engine: Approximately 7.4 quarts (7.0 liters)
• OEM Coolant Spec: Toyota Super Long Life Coolant (SLLC). This is a pink, phosphate-based organic acid technology (P-OAT) coolant.
• Mix Ratio: Pre-mixed 50/50 ethylene glycol solution. Do not dilute further.

Capacity by Engine Option

Flush Interval

Toyota recommends the first coolant flush for vehicles using Super Long Life Coolant at 100,000 miles (160,000 km) or 120 months, whichever comes first. Subsequent flushes are recommended every 50,000 miles (80,000 km) or 60 months.

Severe Duty: If your vehicle regularly experiences severe driving conditions (e.g., towing, extreme temperatures, heavy stop-and-go traffic), consider flushing the coolant more frequently, typically every 30,000 miles or 36 months after the initial flush.

How to Refill & Bleed

1. Safety First: Ensure the engine is completely cool before starting. Wear appropriate safety gear, including gloves and eye protection.
2. Drain Old Coolant: Place a drain pan under the radiator drain plug. Open the drain plug and the radiator cap (or reservoir cap) to allow the coolant to drain completely. For a more thorough flush, consider removing the lower radiator hose.
3. Flush (Optional but Recommended): Once drained, close the drain plug. Fill the system with distilled water. Run the engine with the heater on high until it reaches operating temperature to circulate the water. Drain the water. Repeat this process until the drained water is clear. You can also use a dedicated cooling system flush product according to its instructions.
4. Refill with New Coolant: Close the radiator drain plug and reattach any hoses. Slowly pour the new Toyota Super Long Life Coolant (50/50 pre-mixed) into the radiator until it reaches the top. Fill the overflow reservoir to the "MAX" line.
5. Bleed the System: This is crucial to remove air pockets. Start the engine with the radiator cap off (or loosely fitted). Turn the cabin heater to its highest setting (full hot) and fan speed to low. As the engine warms up, the thermostat will open, and coolant will begin to circulate. Squeeze the upper and lower radiator hoses several times to help dislodge air bubbles. You may see bubbles rise to the surface of the coolant in the radiator. Top off the coolant level as needed.
6. Maintain Level: Once the bubbles subside and the coolant level stabilizes, install the radiator cap. Drive the vehicle for a short period, then let it cool down completely. Recheck the coolant level in the overflow reservoir and top off if necessary. Repeat this process for a few driving cycles to ensure all air is purged.

Note: The 2018 Toyota Camry generally self-bleeds well, but patience is key during the process to ensure all air is removed. There are no specific bleed screws on this model; relying on the radiator fill neck and the expansion tank is sufficient if done correctly.

Common Cooling System Issues

While the 2018 Toyota Camry is generally reliable, some cooling system issues can arise:

• Water Pump Leaks: This is a possibility, especially as the vehicle ages. Look for pink residue or drips under the vehicle, particularly around the front of the engine.
• Radiator Leaks: Radiators can develop leaks over time due to corrosion or damage. Inspect the radiator fins for signs of coolant seepage.
• Thermostat Failure: A failing thermostat can cause the engine to overheat (if stuck closed) or run cooler than optimal (if stuck open). Symptoms include fluctuating temperature gauges or slow engine warm-up.
• Coolant Hoses: Hoses can degrade over time, becoming brittle or soft, leading to leaks or bursts. Regular visual inspection is recommended.
• Coolant Level Sensor Malfunctions: While less common, the coolant level sensor in the reservoir can sometimes malfunction, leading to false warnings on the dashboard.

Regular coolant checks and adherence to the recommended flush intervals are key to preventing these issues and ensuring the longevity of your 2018 Toyota Camry's engine.
