How to Replace the Coolant Recovery Tank in a Honda CR-V

The cooling system of the Honda CR-V is tremendously significant in that it regulates the engine temperature. If the system malfunctions, the car can overheat or eventually fail. An essential element of that system is the coolant recovery tank. If this tank begins to leak or break down, immediate replacement of the coolant recovery tank is imperative.

Position a bucket beneath the radiator and directly below the drain plug. On the Honda CR-V, the plug is on the bottom center of the radiator. In addition, the bucket should have a capacity of at least 2 gallons to prevent overflow.

Open the radiator plug and let the coolant drain into the bucket. Make certain the radiator is cool to the touch before opening the drain. Then pour the coolant into a sealable container for proper disposal.

Remove the nuts, which secure the coolant recovery tank to the Honda CR-V. Use a socket wrench to remove the nuts. You may also need a socket extension, as some models have nuts that are difficult to access. Be sure to put the nuts in a safe place so you won't lose them.

Take a pair of hose clamp pliers and remove the hose clamps. Be careful, because the hoses can have leftover coolant in them. Once removed, cover the hose openings to keep them free of dirt and debris.

Pull the existing coolant recovery tank out and replace it with the new tank. Be sure to align the tank connections with the bolts on the CR-V. Then, reattach the nuts back to the bolts and tighten them with the socket wrench. Verify the tank is securely in place before continuing.

Close the drain plug and refill the radiator with fresh coolant. Next, switch on the engine with the heater set to high. Let it run for 15 or 20 minutes.

Switch off the engine and check for leaks. If none exist, close the hood and clean up your mess.


Never open a radiator that's warm or hot to the touch, as it can erupt and burn anyone in the area with coolant. Be very careful when working with radiator coolant because it's extremely toxic to animals and people.
