Mazda RX-8 How to Replace the Air Conditioner Belt

The belt on the right is the belt for the air conditioner.

It’s that easy. Loosen the bolt. First loosen No. 1 and then loosen No. 2.

It is 17 mm. A long box wrench straight is recommended as it will use loosen the deep part. It’s okay if you loosen it enough to turn it by hand.

The air conditioner tension bolt is 10 mm. It’s really easy to have a long extension and a quick spinner. As you loosen this bolt, the belt will loosen. It is convenient to have a quick spinner because it loosens quite a bit.

To install it, remove the belt, attach a new one, tighten No. 2, lock No. 1, start the engine, turn on the air conditioner, run in to some extent, and check the tension again.

Since it is a V ribbed belt, it is a point to check if it is firmly in the groove of the pulley. Please note that it will be difficult to start the engine in a misaligned state.

The tools used are the upper extension, 10mm box, middle long box wrench 17, 19/3/8 ratchet and quick spinner.
