My radiator is being repaired today. I am taking the opportunity to replace belts, hoses, thermostat, radiator cap.

Am I forgetting anything?

What is the best source for the parts? I have heard that the cap and the thermostat should be mazda only. What about the hoses? Can I get these at Napa/Autozone/Orielly's or should these be from mazda also?

Also, any advice on flushing the cooling system on a rotary? I do not want to do anything too harsh that might compromise the coolant seals.

Thanks in advance.
