Start by parking your Mazda CX on a flat surface. Turn off the engine and engage the parking brake. For added safety, disconnect the battery to prevent any electrical issues during the replacement.
Lift Your Vehicle
Using a jack, elevate the front of your Mazda CX and secure it with jack stands. This will provide you with ample space to work comfortably underneath the vehicle.
Locate the Belt Tensioner
Open the hood and locate the serpentine belt tensioner. It’s usually positioned near the front of the engine, connected to the serpentine belt.
Release Tension on the Belt
Using your belt tensioner tool or a ratchet, carefully rotate the tensioner to relieve tension on the serpentine belt. Once loose, slide the belt off the tensioner pulley. Take note of the belt routing for reinstallation.
Remove the Old Tensioner
With the belt removed, you can now detach the old belt tensioner. Use your socket set to remove the bolts securing it to the engine. Carefully pull the old tensioner out of its position.
Install the New Belt Tensioner
Now it’s time for your new tensioner (PE03-15-980C)! Position it where the old one was removed and secure it using the bolts you just took off. Tighten them to the manufacturer’s specifications using a torque wrench. Refer to the belt routing diagram and reinstall the serpentine belt over the new tensioner. Ensure it sits properly in all the pulleys.
Restore Tension
Rotate the tensioner again using your tool to apply tension to the belt. Make sure the belt is securely in place on all pulleys.
Final Checks
Before lowering your vehicle, double-check that everything is securely fastened and that the belt is properly routed. Reconnect the battery and start the engine. Listen for any unusual noises and observe the belt’s operation.
Lower the Vehicle
Carefully lower your Mazda CX back to the ground using the jack. Once stable, take it for a short test drive to ensure everything is functioning smoothly.
