Locate the old reservoir and carefully remove it using the appropriate tools for the 4-screw mount. Then, install the new kit in its place, ensuring the screws are tightened properly. As for maintenance, regularly check the fluid level in the reservoir. If it's low, top it up with the recommended fluid. Be aware that this product can't be returned to the original place of purchase. If you face any problems, don't hesitate to contact the manufacturer directly. Keep the kit clean and dry to prolong its lifespan.
