1992 Mitsubishi 3000GT VR-4 Timing Belt Installation

This guide covers the installation and removal for 3.0L V6 - VINS [B,C,S]' '1992 ENGINES Mitsubishi 3.0L V6. Removal (Diamante SOHC)
1. Remove left front and left side splash shields. Using engine hoist, lift engine just enough to remove weight from engine mounts. Remove drive belts. Remove A/C tensioner pulley and bracket. Remove engine mount bracket bolts in sequence. Lubricate reamer bolt with penetrating oil before and during removal. See Fig. 7 . Remove power steering pump, leaving hoses attached. 2. Remove engine support bracket. Remove crankshaft pulley. Remove timing belt covers. Remove flange from crankshaft. See Fig. 8 . Rotate crankshaft to align all timing marks. See Fig. 9 . Loosen belt tensioner bolt, and rotate belt tensioner counterclockwise to release belt tension. 3. If reusing timing belt, mark belt to indicate direction of belt rotation. Loosen tensioner bolt. Pry tensioner counterclockwise to relieve belt tension. While holding tensioner, tighten tensioner bolt. Remove timing belt.

Installation
1. If original belt is to be reinstalled, install in original running direction. Install timing belt onto crankshaft sprocket, then around left camshaft sprocket, with all slack removed from tension side of belt. Route timing belt onto water pump pulley, right camshaft sprocket, and tensioner. Apply torque to rear camshaft pulley to tighten belt. Ensure all timing marks are aligned. 2. Install flange onto crankshaft. Loosen belt tensioner bolts slightly, and allow tensioner to apply belt tension. Using Crankshaft Socket (MD998716-01), rotate crankshaft 2 revolutions clockwise. DO NOT rotate counterclockwise. Realign all timing marks. Tighten belt tensioner bolts to specification. Using belt tension gauge, measure belt tension halfway between crankshaft sprocket and camshaft sprocket on side opposite belt tensioner. 3. Belt tension should be 44-66 lbs. (20-30 kg). To install remaining components, reverse removal procedure. Install proper length bolts in timing belt covers. See Fig. 10 . Tighten bolts to specification. See appropriate TORQUE SPECIFICATIONS table.
