Timing belts on Mitsubishi SOHC's aren't "that bad" to get to (at least on trucks...) Requires removal accessory drive belts, fan + water pump pulley and crank pulley to gain access to the timing covers. They're in 2 pieces and the upper half is obviously the easier one to get to. Be aware that there is a small 'seal' that runs around the edge of the inside of the timing cover lower half that goes brittle so be careful during removal.

*tip for cracking the crank pulley bolts - use a deep socket and extension bar with a length of pipe as a sleeve around the bar as an extender. Fit it to the crank bolt and turn clockwise until it rests firmly on the frame (make sure it doesn't rest on anything that could be damaged) Disconnect the main coil lead and crank the ignition in one or 2 very short bursts. Guaranteed to crack the bolt free every time
