How to Replace the Timing Belt on a 2002 Acura TL
The Acura TL is a luxury sports car in production since 1996. The 2002 model is a second generation Acura, which includes the 1999 through 2003 models. The standard engine for all second generation Acuras in North America is a six-cylinder, 3.2-liter engine with a double overhead camshaft. The timing belt synchronizes the crankshaft with the camshafts, so the cylinder valves open and close at the right time.
Instructions
- 1
Disconnect the cable for the negative battery terminal and the ignition coil cover with a socket wrench.
2Place a cushion such as a wooden board on top of a floor jack. Place the floor jack under the oil pan, and raise the vehicle. Remove the front wheel assemblies with a lug wrench. Disconnect the splash shield under the vehicle and remove the accessory drive belts from their respective pulleys.
3Lower the vehicle with the floor jack and raise it slightly to take the weight of the engine off the engine mounts. Disconnect the mounting bolts for the side mount on the front of the engine, and remove the side mount. Remove the bolt for the dipstick tube with a socket wrench, and detach the tube from the engine.
4Rotate the crankshaft clockwise to align the white timing mark on the crankshaft pulley with the pointer on the lower rear timing belt cover. The timing marks on the camshaft pulleys must also align with their respective timing marks on the upper rear timing belt cover.
5Hold the crankshaft pulley in place with Holder Attachment Tool 07MAB-PY3010A. Remove the crankshaft pulley bolt with a socket wrench and a 19mm socket. Pull the crankshaft pulley from its shaft with Holder Attachment Tool 07MAB-PY3010A.
6Disconnect a bolt for a battery clamp with a socket wrench. Grind a 45-degree bevel on the threaded end of the bolt. Screw the bolt into the hole in the right cylinder head by hand to hold the adjuster for the timing belt in place. Disconnect the engine mount bracket. Turn the mounting bolt for the idler pulley five turns counterclockwise with a socket wrench, and detach the timing belt.
7Disconnect the spark plugs. Turn the crankshaft sprocket clockwise to align the timing mark on the crankshaft sprocket with the timing mark on the oil pump. The timing mark on the camshaft pulleys must also align with their respective timing marks on the rear timing belt covers.
8Disconnect the battery clamp bolt with a socket wrench and replace it into its original hole. Remove the timing belt tensioner and place it into a soft-jawed vise with the maintenance bolt pointed up. Remove the maintenance bolt with a socket wrench. Place Stopper Tool 14540-P8A-A01 onto the tensioner to maintain the tension setting. Turn the screw inside the maintenance hole clockwise with a flat-blade screwdriver to compress the bottom of the tensioner.
9Replace the gasket for the maintenance bolt on the timing belt tensioner and tighten the bolt to 6 ft. lbs. with a torque wrench. Install the tensioner and tighten its mounting bolts to 33 ft. lbs.
10Mount the new timing belt to the crankshaft sprocket, idler pulley, left camshaft sprocket, water pump pulley, right camshaft sprocket and adjusting pulley in that order. Remove Stopper Tool 14540-P8A-A01 from the timing belt tensioner.
11Install the bolts for the engine side mount with a torque wrench. Tighten the No. 10 bolts to 33 ft. lbs., and tighten the No. 6 bolts to 104 in. lbs. Connect the timing belt covers with a socket wrench. Install the crankshaft pulley with Holder Attachment tool 07MAB-PY3010A. Tighten the crankshaft pulley bolt with a torque wrench and a 19mm socket to 181 ft. lbs.
12Turn the crankshaft five complete turns clockwise to position the timing belt, and align the timing marks. Connect the dipstick tube, accessory drive belts, splash shield and front wheel assemblies. Lower the vehicle and replace the ignition coil cover. Attach the cable to the negative battery terminal.
