DESCRIPTION

To insure proper and efficient operation of the Air Conditioning System, it is of extreme importance to verify that the Air Conditioning System is properly charged. Also, please note that over-charging the Air Conditioning System can cause higher than normal system pressures which could result in Air Conditioning System component damage.

The recommended refrigerant charge for 1988 Mazda vehicles is as follows:

323, RX-7, B-Series Truck ............................ 28 ounces
626, MX-6 ................................................ 35 ounces
929 ......................................................... 39 ounces




QUICK VISUAL CHECK

It is possible to make a quick visual check of the Air Conditioning System to verify the correct refrigerant charge.

1) Run the engine at fast idle.
2) Operate the Air Conditioning System at maximum cooling for approximately 5 minutes.
