WARNING
The three 1.8L engines use different oil pumps. When replacing the pump be sure that you have the correct part number. Match the crankshaft timing mark on the new oil pump with the timing mark on the old oil pump, because the timing marks are in different locations. If an oil pump is used with the timing mark in the wrong position the pistons may contact the valves.

  1. Install the pickup screen, then the oil pan. Tighten the oil pan bolts to 104 inch lbs. (12 Nm).
