How to remove and install the coolant reservoir on Mazda RX-7?

The coolant reservoir falls on the right side of the radiator and must be periodically inspected to see whether it has any cracks, damage, and leakages. To empty the reservoir, firstly, open the hose clip with a pair of pliers and push it to the rear on the hose approximately two inches. Then detach the water hose on the top of the reservoir. The reservoir may then be pulled off its clips on the radiator by pulling out on the bottom and at the same time pulling the reservoir straight up since it is held in place by a metal clip attached to the radiator. To install, insert the reservoir that is mounted on the mounting clips until it fits correctly and then reconnect the water hose with the clip.
