Drain the cooling system. Save and reuse if the coolant is relatively new and still in good condition. The retaining clip must be removed for 2015 models and older ones, while the coolant reservoir/expansion tank must be unclipped from its mounting bracket. In case of 2016 models onwards, the fastener for mounting the coolant reservoir/expansion tank has to be removed. Loosen the clamps and move them back on the hoses, then detach the hoses. Remove the expansion tank from its mount. For inside deposits, use soapy water and a brush to scrub it clean. Inspect tank thoroughly for cracks if any replace them. Refilling is just like removing.

To remove the coolant from the compartments, first take out as much of it as possible using a vacuum apparatus. If it is in good condition, save the leftover fluid. Next, raise the container to disconnect an overflow hose-turn two bolts on a vehicle. Upon this instance, you can reuse such a compartment: use soapy water and a brush in its cleaning to eliminate all deposits and see if there are any fractures on it. If any splits are identified, substitute the whole unit. Just do everything that you were doing vice versa when installing this accessory again. Lastly, fill up the container with proper mixture of anti-freeze and water constituents.
