How to Change the Timing Belt on a 1994 - 2000 Acura RL MFI 6 Cylinder 3.5L Engine
Replace the timing and balancer shaft belts at no more that 105,000 miles (168,000km). Acura also specifies that under extreme conditions the timing and balancer shaft belts should be replaced more frequently, at 60,000 miles (100,000 km). These abnormal conditions include very high temperatures over 110°F (43°C) or very low ambient temperatures of minus 20°F (-29°C).
Removal & Installation
1.Turn the engine so that the No. 1 piston is at the top dead center (TDC).
2.Disconnect the negative battery cable.
3.Remove the engine cover.
4.Remove the air cleaner assembly and the intake tubing.
5.Loosen the adjusting nut and then the mounting nuts to allow the alternator belt to be removed.
6.Loosen the adjusting and idler pulley bracket bolt on the (A/C) to free the belt.
7.Remove the power steering pump by loosening the adjusting bolts and removing the mounting bolts.
8.Remove the TCS upper and lower bracket assemblies.
9.Remove the TCS control valve assembly.
10.Disconnect the Vehicle Speed Sensor (VSS).
11.Remove all vacuum hoses.
12.Remove the breather hose from the engine.
13.Remove the ignition control module (ICM) bracket assembly.
14.Remove the idler pulley bracket as well as the dipstick tube.
15.Separate the crankshaft pulley from the crankshaft.
16.Remove the timing covers.
17.Relieve the tension from the balancer belt by loosening the adjusting bolt no more than 180°.
18.Remove the balancer belt.
19.Relieve the tension from the timing belt by loosening the adjusting bolt no more than 180°, then remove the timing belt.
Do not turn the engine with the timing belt removed. This is an interference engine and the pistons may hit the valves if the valve train is out of sync with the crankshaft.
20.Remove the spark plugs from the cylinder head.
21.Remove the timing belt guide plate by first removing the balancer belt drive.
22.Position the number one piston at top dead center.
23.Position the camshaft pulleys at the top dead center mark on the back cover.
24.Install the timing belt in the following order:
A.Loop the belt over the timing belt drive pulley.
B.Install the timing belt around the adjusting pulley.
C.Place it around the left camshaft pulley.
D.Install it under the bottom of the water pump pulley.
E.Route the belt around the right camshaft pulley.
25.To tension the timing belt, loosen the adjusting nut.
26.Once the adjuster spring has applied tension to the timing belt, retighten the adjusting nut.
27.Install the lower and upper timing belt covers.
28.After installing the crankshaft pulley, tighten the bolt to the proper specs.
29.To check that the timing belt has positioned itself on the pulley by rotating the crankshaft pulley about five to six turns.
30.Adjust the timing belt tension and check that the crankshaft and camshaft pulleys are at top dead center (TDC).
31.If the camshafts are not at TDC, remove the timing belt and adjust the pulleys by repeating the above procedure.
32.Install the remaining components in the reverse of removal procedure.
33.Connect the negative battery cable.
