Download 1. General note. CAUTION: In MJ ‘96 the camshaft timing belt was revised. Coolant pumps and timing belt tensioners with different idler pulleys are fitted in production. In service there are now only coolant pumps with two edges on the idler pulley available. It should be noted that when renewing the timing belt tensioner, a tensioner without an edge must not be fitted in conjunction with a coolant pump without edges. Converting a mechanical timing belt tensioner to an automatic timing belt tensioner is NOT permissible. In addition, since MY ‘96 PTFE oil seals have been fitted at the front and rear of the crankshaft instead of the familiar Viton oil seals. CAUTION: Since 08.98 (build code WP), a revised oil pump has been fitted in conjunction with a revised oil pressure switch (green cover), and 5W 30 engine oil has been used. It should be noted that up to and including 07.98 (build code WM), an oil pressure switch with a black cover was fitted, and 10W-40 engine oil was used.
