Replacing Serpentine belt on a Toyota camry 2003—
Step 1--Examine the belt placement of your Toyota Camry fan belt so that you will remember how to put it back once you have removed it. Refer to the vehicle owner's manual for further information. Locate the pivot bolt on the front passenger side of the engine. Loosen the pivot bolt with a socket wrench.
Step 2--Loosen the adjustment locking bolt that is just below the tensioner pulley with a socket wrench, and then loosen the tensioner pulley to allow the belt to move free.
Step 3--Check the belt for any signs of cracking or irregular wear, so you can fix any problems that may exist with the pulleys. Remove the fan belt from the pulleys on the engine and take it out of the engine compartment.
Step 4--Wrap the new fan belt around each of the pulleys the same way it came out. When you have the belt in place, tighten the tensioner pulley with a socket wrench.
Step 5--Tighten the adjustment locking bolt and the pivot bolt with a socket wrench, and then look over the engine to check that everything is back in place.
Step 6--Turn the vehicle engine on and watch it for a few minutes to verify that everything is operating properly, then turn the engine off.
