Serpentine Belt

Begin by detaching the accessory Drive Belt followed by raising the vehicle properly before starting the a/c Drive Belt replacement. Start by removing both bolts that secure the engine shield and then removing the shield from its position. The ratchet should be inserted into the a/c belt tensioner adapter opening for clockwise tensioner rotation before extracting the belt from all pulleys. Use a wrench to depress the a/c belt tensioner before removing the ratchet tool. The staff should then clean and check each pulley belt surface. To fit the a/c belt you must first wrap it around the crankshaft balancer and after that you can install the ratchet into the a/c Drive Belt tensioner adapter opening to turn the tensioner clockwise. Install the a/c belt first on the idler pulley and then circle it around the a/c compressor pulley followed by carefully releasing tension from the a/c belt tensioner before removing the ratchet. Before installing the engine shield check the installed a/c belt sits correctly and the engine shield bolts need to be tightened to 20 nm (15 ft. Lbs.). After the process, lower the car down while placing the accessory Drive Belt back into position.

The first step to replace the air conditioning Drive Belt requires removing the accessory Drive Belt followed by securely raising the vehicle. Unfasten and remove both engine shield bolts followed by the engine shield. A ratchet inserted into the opening of the a/c belt tensioner adapter must be used to rotate the tensioner in a clockwise direction before the belt can be removed from the pulleys. Clean and inspect the belt sides of all pulleys while the ratchet is removed from the a/c belt tensioner which you have carefully untensioned. Place the a/c belt around the crankshaft balancer before inserting a ratchet into the tensioner adapter opening to let out tension from the a/c Drive Belt tensioner. After positioning the a/c belt on the idler pulley and a/c compressor pulley begin slowly letting go of the a/c belt tensioner tension until you can remove the ratchet. Before putting back the engine shield and tightening engine shield bolts to 20 nm (15 ft. Lbs.), check that the a/c belt has correct placement and positioning. To complete the process lower the vehicle until you can install the accessory Drive Belt.

The first step to replace an air conditioning Drive Belt requires removal of the accessory Drive Belt. First apply the breaker bar into the adapter hole on the air conditioning belt tensioner to rotate the tensioner clockwise and remove the belt tension on the belt. After removing the belt from its pulleys free the tension on the tensioner through the breaker bar before completing the removal. Drive your attention to clean and inspecting the belts running along all pulleys. Install the a/c belt onto the crankshaft balancer and feed the breaker bar's (Breaker Bar) similar end into the a/c Drive Belt tensioner adapter opening before turning the belt tensioner clockwise to loosen it. Workers should fit the a/c belt across the idler pulley before wrapping it around the a/c compressor pulley. After that they should conduct a smooth tension release operation on the a/c belt tensioner then replace the breaker bar. Examine the a/c belt for appropriate mounting while checking its alignment prior to adding the accessory Drive Belt.

First loosen the air cleaner outlet duct clamps positioned at the Throttle Body and maf/iat sensor component before disconnecting the radiator inlet hose clip from the outlet duct and eliminating the air cleaner outlet duct. A breaker bar fitted with a hex-head socket enables users to turn the Drive Belt tensioner bolt clockwise for belt tension release. Release the Drive Belt tensioner first by loosening its clamp then remove the belt from all pulleys and the tensioner. Next slowly release the tensioner pressure using the breaker bar before removing it along with the matching socket. Inspect all belt surfaces on the existing pulleys before directing the Drive Belt through all other pulleys except the idler pulley. The breaker bar with hex-head socket goes back on the tensioner bolt for relief when rotating it clockwise to buckle in the Drive Belt which gets placed under the idler pulley. After removing the socket and breaker bar the tension on the belt tensioner can be carefully relaxed. The Drive Belt must be inspected for correct positioning and alignment before installing the air cleaner outlet duct with its arrow facing the Throttle Body attaching stud. Reconnect the radiator inlet hose clip before securing all three air cleaner outlet duct clamp screws at their respective locations to 7 nm (62 inch lbs.).

The Drive Belt replacement procedure for 4.8l, 5.3l and 6.0l engines starts by loosening the air cleaner outlet duct clamps which secure the Throttle Body and mass airflow (MAF) / intake air temperature (IAT) sensor. After disconnection of the radiator inlet hose clip from the outlet duct, remove the air cleaner outlet duct. A hex-head socket breaker bar can be used to turn the Drive Belt tensioner bolt clockwise which reduces belt tension before removing the belt from the pulleys and the Drive Belt tensioner while also easing tension when done. Before placing the new Drive Belt onto the system, clean and check the surfaces of all pulleys while routing the belt around all pulleys excluding the idler type. After installing the hex-head socket on the belt tensioner bolt with a breaker bar proceed with clockwise rotation to decrease tension while positioning the Drive Belt beneath the idler pulley before you unwind the tension. Inspection of the Drive Belt should confirm its proper alignment and installation before placing the arrow at the Throttle Body end of the duct in line with the Throttle Body stud for duct reinstallation. The next step includes attaching the radiator inlet hose clip to the outlet duct and tightening air cleaner outlet duct clamps at the Throttle Body and the maf/iat sensor to 4nm (35 inch lbs.).

The Drive Belt replacement procedure starts with duct clamp loosening at the Throttle Body and mass airflow/intake air temperature sensor before disconnecting the radiator inlet hose from the outlet duct and removing the air cleaner outlet duct. A breaker bar equipped with a hex-head socket on the Drive Belt tensioner bolt should be used for clockwise rotation to lower belt tension. First remove the belt from its resting position on the pulleys and tensioner. Then remove tension from the Drive Belt tensioner while removing the breaker bar and socket. The inspection of all belts should start with checking the pulley surfaces. Install the new Drive Belt over all pulleys except the idler pulley. Insert the breaker bar with its hex-head socket onto the Belt Tensioner Bolt where you should turn the tensioner clockwise to relax the belt. Then install the Drive Belt below the idler pulley. Remove the breaker bar along with the socket while following the slowness when releasing tension from the belt tensioner. The Drive Belt should be checked for correct installation and alignment before installing the air cleaner outlet duct. Align the arrow on the Throttle Body end of the duct with the Throttle Body attaching stud. To conclude the installation reconnect the radiator inlet hose clip to the outlet duct then tighten all air cleaner outlet duct clamp screws at both the Throttle Body and maf/iat sensor to 7 nm (62 inch lbs.).

Start the replacement process of the air conditioning (A/C) Drive Belt through accessory Drive Belt removal and vehicle secure hoisting. First remove the engine shield bolts before taking out the engine shield. Install a ratchet into the tensioner adapter opening to rotate the tensioner clockwise while releasing belt tension. After that the a/c belt may be taken off the pulleys. Release the tension on the a/c belt tensioner at a slow pace and then detach the ratchet before cleaning and checking the surfaces of all pulleys. Place the a/c belt around the crankshaft balancer after which apply a ratchet into the a/c Drive Belt tensioner adapter opening to run the tensioner clockwise and tension the belt. Position the a/c belt above the idler pulley followed by its installation around the a/c compressor pulley. Subsequently release the a/c belt tensioner tension very slowly and extract the ratchet. The engine shield placement must include a verification step for proper alignment of the a/c belt which must be inspected before installation according to the fastener notice. You should first install engine shield bolts and tighten them to 20 nm (15 ft. Lbs.) before letting the vehicle down and putting back the accessory Drive Belt.

You must start replacement of the accessory Drive Belt by loosening the air cleaner outlet duct clamps at the Throttle Body and maf/iat sensor followed by removing the radiator inlet hose clip and the air cleaner outlet duct. A hex-head socket fitted breaker bar needs to be used on the Drive Belt tensioner bolt for clockwise rotation that reduces belt tension so you can remove it from all pulleys including the tensioner. Release the tension on the Drive Belt before removing the breaker bar together with the socket. Clean all pulley belt surfaces and inspect them thoroughly. After placing the Drive Belt across all pulleys bar the idler, use the breaker bar and hex-head socket to engage the tensioner for clockwise rotation which reduces belt tension. The Drive Belt should be lowered under the idler pulley then you should slowly relax the tension before taking out the breaker bar and socket. Adjust the Drive Belt according to its correct position by lining up the Throttle Body stud attachment marker with the Throttle Body before attaching the outlet duct from the air cleaner. Reinstall the radiator inlet hose clip before securing all air cleaner outlet duct clamp screws at their respective locations with torque set to 7 nm (62 inch lbs.).

The starting process to change the Drive Belt on 4.8l, 5.3l, and 6.0l engines begins with loosening the clamps on the Throttle Body air cleaner outlet duct and maf/iat sensor and afterward disconnecting the inlet hose clip from the outlet duct before removing the air cleaner outlet duct. Apply a hex-head socket on the Drive Belt tensioner bolt using a breaker bar to turn it clockwise until the belt tension drops. Afterwards, remove the belt from its pulley positions and Drive Belt tensioner before gently letting go of the tension from the belt. Before installing the new Drive Belt you must clean and inspect the belt surfaces of all the pulleys except the idler pulley. Reinsert the breaker bar featuring the hex-head socket attached to the belt tensioner bolt and turn it clockwise to decrease tension before putting the Drive Belt under the idler pulley followed by releasing the tension at a slow pace. After detaching the breaker bar and socket users should verify Drive Belt alignment while directing the Throttle Body arrow to match the Throttle Body attaching stud before reattaching the air cleaner outlet duct. Screw the radiator inlet hose clip onto the outlet duct after completing clamp installation at both the Throttle Body and maf/iat sensor places with 4 nm (35 inch lbs.) torque.

The first step for accessory Drive Belt replacement includes hood opening and duct removal from the air cleaner outlet. The Drive Belt tensioner bolt needs a hex-head socket connector to the breaker bar so users can turn the tensioner clockwise to ease belt tension. After detaching the Drive Belt from its position between the pulleys and tensioner step until you can slowly decrease the tension on the tensioner before using a breaker bar and socket to remove both items. Thoroughly clean the belt surfaces that exist on all pulleys. To tension the Drive Belt for installation you should run it past all pulleys except the idler pulley and connect a breaker bar equipped with a hex-head socket to the tensioner bolt for clockwise rotation. Install the Drive Belt under the idler pulley then slow down tension release before removing the breaker bar with hex-head socket. First inspect both the Drive Belt for correct position and alignment then reinstall the air cleaner outlet duct and start the vehicle; check the Drive Belt works correctly before completing hood closure.
