Procedure? ....after disconnecting the two hoses, is it just the reverse procedure and adding fluid or does the system need bleeding. Thanks.

I used a turkey baster to remove the minimum amount of coolant needed to do the install with making a mess. Disconnect the top and bottom hoses, remove and install the new reservoir, connect the hoses back, and refill the tank with coolant. Just to be safe, I ran the engine for a few minutes with the cap off and the coolant capacity full until the heater came on. Put the cap back on and take it for a test drive to ensure no leaks, etc. The coolant tank is high enough up in the engine bay to where a full bleed of the system isn't necessarily required, although it wouldn't hurt. I didn't need to, however.

Power Steering Tank or Coolant ?

Just an FYI. According to the Mazda 2011 MX5 manual, before starting the engine, jack up the front wheels off the ground and turn the wheel lock to lock a couple of times. Check the reservoir and if the fluid is below full indication point add fluid and repeat. I did not do this step the first time and my pump was making noise upon turning. Once I did this procedure, it was 100% back to normal.
