Serpentine Belt

You must start by using a 3/8 inch breaker bar to rotate the drive belt tensioner arm clockwise to decrease drive belt tension and afterward remove both the drive belt and tensioner arm tension. When installing the new drive belt it should be placed above all the pulleys except the drive belt tensioner pulley before applying torque to the arm with a 3/8 inch breaker bar until it rotates clockwise. Before releasing tension from the drive belt tensioner pulley it is vital to position the drive belt over this component. Check that the drive belt has correct placement around every pulley before concluding the installation.

Start by removing both the air conditioning (A/C) Drive Belt together with its accessory counterpart and securing the vehicle before moving forward. The procedure starts by taking out engine shield bolts followed by the removal of the engine shield. Beginning by inserting a ratchet into the a/c belt tensioner adapter opening the technician can rotate the tensioner clockwise thus weakening the belt tension before removing the a/c belt from the pulleys. The tension on the a/c belt tensioner should be released carefully before removing the ratchet and cleaning and checking the belt surfaces on all pulleys. The crankshaft balancer receives the a/c belt as an installation step while the clockwise motion of the a/c Drive Belt tensioner adapter opening using a ratchet reduces belt tension. Lower the a/c belt over the idler pulley before wrapping it around the a/c compressor pulley then let off the a/c belt tensioner tension with slow pressure while removing its ratchet. Check the a/c belt installation and alignment before reattaching the engine shield with bolts which need to be tightened at 20 nm (15 ft. Lbs.). The installation process ends with lowering the vehicle while fitting the accessory Drive Belt.

Begin the accessory Drive Belt replacement by taking away the air cleaner assembly followed by the retaining bolt on the coolant recovery reservoir then place the reservoir aside. A breaker bar connected to a hex-head socket should be used to turn the Drive Belt tensioner counterclockwise for belt tension reduction. Uninstall the belt from its positions on the pulleys and the Drive Belt tensioner before you release tension from the Drive Belt tensioner at a steady pace. You need to clean all pulleys after you remove their breaker bar along with the socket from the tensioner bolt. When installing a new belt users must first guide it through all pulleys without the idler but after that they must position the breaker bar fitted with hex-head socket on the belt tensioner bolt and push it clockwise until sufficient tension is reached. Insert the Drive Belt under the idler pulley before slowly eliminating tension from the belt tensioner using the breaker bar and socket on the tensioner bolt. Check that the Drive Belt is correctly positioned and align it properly, then position the coolant recovery reservoir and tighten the retaining bolt to 11 nm (97 inch lbs.). Finish the procedure by reinstalling the air cleaner assembly.

The first step for accessory Drive Belt replacement involves loosening the air cleaner outlet duct clamp at the Throttle Body while disconnecting the electrical maf sensor connector before you take off the air cleaner housing assembly. A breaker bar with hex-head socket installed on the Drive Belt tensioner bolt should be used to turn the tensioner clockwise until the belt tension is released. At this point remove the belt from pulleys and tensioner before proceeding. Slowly remove the tension from the Drive Belt tensioner before removing the breaker bar together with socket. Maintain visual and clean inspection of the surfaces that form the belts on all pulleys. First install the Drive Belt only on the pulleys except the idler pulley before it includes the breaker bar with the hex-head socket on the tensioner bolt to reduce tension. After placing the belt under the idler pulley install a breaker bar along with its socket to the belt tensioner. Slowly loosen tension and remove both tools from the system. After inspecting and correct positioning of Drive Belt installation you should reinstall the air cleaner assembly followed by connecting the maf sensor's electrical connector. Complete the procedure by fastening air cleaner outlet duct clamps at the Throttle Body at 7 nm (62 inch lbs.).

Your first step should be lifting the vehicle securely and eliminating the accessory Drive Belt before the replacement operation. You should remove both the engine shield bolts and afterward the engine shield. A ratchet inserted into the a/c belt tensioner adapter opening should rotate the tensioner clockwise until the belt has no tension before removing the belt from the pulleys. Proceed to remove the ratchet tool before cleaning all pulley belts surfaces when the tension on the a/c belt tensioner reaches the proper state. To install the a/c belt start by placing it on the crankshaft balancer before using a ratchet with the corresponding opening on the a/c Drive Belt tensioner adapter to rotate the tensioner clockwise. First position the a/c belt over the idler pulley and around the a/c compressor pulley and afterwards let out the tension on the a/c belt tensioner slowly before removing the ratchet. Verify the a/c belt installation and alignment before putting back the engine shield and tightening its bolts to 20 nm (15 ft. Lbs.). Lower your vehicle afterwards before reinstalling the accessory Drive Belt.

You should start by taking off the accessory Drive Belt before raising the car to work on the air conditioning (A/C) Drive Belt replacement. The first step involves removing engine shield bolts and subsequently removing the engine shield. A ratchet inserted into the a/c belt tensioner adapter opening will allow clockwise rotation of the tensioner to relieve belt tension before the a/c belt can be removed from the pulleys. Remove the ratchet tool before cleaning all pulleys while inspecting their Drive Belt surfaces. Slowly decrease tension from the a/c belt tensioner during this process. Augment the a/c belt onto the crankshaft balancer before using a ratchet inside the a/c Drive Belt tensioner adapter opening to rotate and loosen tension. The a/c belt should be threaded through the idler pulley and over the a/c compressor pulley afterward release the tension from the a/c belt tensioner by turning its ratchet clockwise. Check the correct installation and positioning of the a/c belt before putting back the engine shield and fastening the engine shield bolts to 20 nm (15 ft. Lbs.). Install the accessory Drive Belt afterward lowering the vehicle to its position.

The first step for accessory Drive Belt replacement starts with unfastening the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor before disconnection the radiator inlet hose clip from the outlet duct and subsequent removal of the air cleaner outlet duct. Use a breaker bar equipped with a hex-head socket on the Drive Belt tensioner bolt to turn it clockwise and tension the belt will decrease. After releasing the tension on the Drive Belt tensioner remove the breaker bar and socket. Then take off the belt from pulleys as well as the Drive Belt tensioner. The inspection should cover belt surfaces on all pulleys for cleanliness. The installer should start by placing the Drive Belt properly on all pulleys without the idler pulley followed by inserting the breaker bar with hex-head socket onto the belt tensioner bolt to achieve tension release through clockwise rotation. Follow these steps to install the Drive Belt under the idler pulley and gradually let go of the tension on the belt tensioner before taking out the breaker bar along with the socket. A proper check of the Drive Belt should happen alongside its correct positioning alignment where the arrow at the Throttle Body end of the duct matches the Throttle Body attaching stud . After that, install the air cleaner outlet duct. Before the end of the installation process, attach the radiator inlet hose clip to the outlet duct while tightening all Throttle Body and maf/iat sensor clamp screws to 7 nm (62 inch lbs.).
