1989 Chrysler New Yorker Timing Belt Installation Instructions

The tenth generation of the Chrysler New Yorker includes the 1988 through the 1993 model years, and has little resemblance to the previous generation of the New Yorker. The standard engine for the 1989 Chrysler New Yorker is a six-cylinder, 3.0-liter engine made by Mitsubishi. This engine uses a timing belt to coordinate the movement of the crankshaft and camshaft. The timing belt wears out at regular intervals, and its replacement is a part of routine maintenance.

Tools Used: Socket wrench set, Spanner tool MB990775, Torque wrench set

Timing Belt Installation

Disconnect the cover for the front rocker arm with a socket wrench. Turn the crankshaft clockwise to align the timing mark on the crankshaft damper with the corresponding mark on the engine. Turn the crankshaft clockwise by a full turn if any of the valve springs are still compressed.

Remove the cable from the negative battery terminal with a socket wrench and disconnect the outer timing belt covers from the engine. Loosen the bolt on the timing belt tensioner to relieve the pressure on the timing belt and remove the timing belt. Move the tensioner away from the engine as far as possible and tighten the bolt on the tensioner.

Hold the camshaft sprocket in place with Spanner tool MB990775. Remove the bolt and washer from the sprocket with a socket wrench. Align the groove on the camshaft sprocket with the groove on the camshaft. Tighten the bolt on the sprocket to 70 foot -pounds with a torque wrench. Remove Spanner tool MB990775 from the sprocket.

Turn both camshafts clockwise to align their timing marks with the timing marks on the alternator bracket and inner timing belt cover. Turn the crankshaft clockwise to align its timing mark with the timing mark on the oil pump.

Install the new timing belt to the crankshaft sprocket while maintaining tension on the front side of the timing belt. Place the timing belt over the front camshaft sprocket, water pump pulley, rear camshaft sprocket and inside the belt tensioner, in that order. Keep tension on the timing belt as you install it, except for the portion on the timing belt adjuster.

Turn the front camshaft counterclockwise to apply tension to the timing belt. Ensure that the timing mark aligns once again, and connect the flange for the crankshaft sprocket with a socket wrench.

Loosen the bolt on the timing belt tensioner, causing the tensioner spring to apply tension to the timing belt. Turn the crankshaft two complete turns clockwise until its timing marks aligns once again. Tighten the bolt on the timing belt tensioner to 19 foot-pounds with a torque wrench.

Install the outer timing belt covers and the rocker arm cover with a socket wrench. Connect the cable for the negative battery terminal and test the vehicle for proper operation.
