Acura Timing Belt Installation

The Acura is a mid-size luxury sports car, manufactured since 1996. The engine for many late-model Acuras is Hondas J32A engine, which is a six-cylinder, 3.2-liter engine with a single overhead camshaft. The timing belt on this engine keeps the camshaft and crankshaft synchronized, and generally requires replacement every 60,000 miles. The primary consideration in installing the timing belt in an Acura is keeping the crankshaft and camshaft properly aligned during the procedure.

Instructions

1

Disconnect the negative battery cable with a socket wrench and remove the cover of the ignition coil. Raise the vehicle with a jack and support it on jack stands. Disconnect both front tires with a lug wrench. Remove the splash shield below the vehicle and detach the accessory drive belts.

2

Place a wooden plank on top of a floor jack and position the floor jack under the oil pan of the vehicle. Raise the floor jack slightly to take the engines weight off the side mount. Disconnect the bolts that attach the side mount to the engine and chassis with a socket wrench. Remove the side mount from the front of the engine.

3

Disconnect the mounting bolt for the dipstick tube with a socket wrench. Remove the dipstick from its O-ring mount. Remove the covers on the timing belt to expose the timing belt on the camshaft pulleys.

4

Turn the crankshaft clockwise to align the timing marks. The white mark on the crankshaft pulley must align with the timing mark on the cover of the timing belt cover. The timing marks on the camshaft pulleys must align with the timing marks on the rear upper cover of the timing belt.

5

Hold the crankshaft pulley in place with Holder Attachment Tool 07MAB-PY3010A. Disconnect the bolt on the crankshaft pulley with a socket wrench and pull the crankshaft pulley from the engine.

6

Remove one of the battery clamp bolts with a socket wrench. Screw the bolt into the hole at the base of the right cylinder head by hand to hold the timing belt adjuster in place. Remove the engine mount bracket and loosen the bolt for the idler pulley by five turns. Remove the timing belt and spark plugs.

7

Remove the bolt from the right cylinder head by hand and screw it into its original hole on the battery clamp with a socket wrench. Remove the timing belt tensioner and attach Stopper tool 14540-P8A-A01 to hold the auto-tensioner in place.

8

Repeat Step 4 to realign the timing marks on the crankshaft and camshaft, if necessary. Install the timing belt tensioner, and remove Stopper tool 14540-P8A-A01 to release the tensioner.

9

Install the new timing belt onto the crankshaft sprocket, idler pulley, left camshaft sprocket, water pump pulley, right camshaft sprocket and adjusting pulley in that order. Tighten the mounting bolt on the idler pulley bolt to 33 foot-pounds with a torque wrench. Connect the bolts that attach the engine mount to the engine. Tighten the No. 6 bolt to 104 inch-pounds and tighten the No. 10 bolts to 33 foot-pounds with a torque wrench.

10

Attach the timing belt covers with a socket wrench. Connect the crankshaft pulley and tighten its bolt by hand. Torque the crankshaft pulley bolt to 181 foot-pounds with a torque wrench and Holder Attachment tool 07MAB-PY3010A.

11

Rotate the crankshaft at least five complete clockwise turns to position the timing belt on the sprockets, and align the timing marks align once again. Perform Steps 1 through 3 in reverse order to install the remaining components. Adjust the tension on the drive belts.
