Engine - Coolant Loss
Number 84-6-47 Date 6/84Subject: CRACKED CYLINDER HEAD ON 1.8L (L46 AND LJ9) AND 2.0L (LQ5, LQ2, AND LR9) L-4 ENGINES - 1982-84 2000
Some 2000 engines may develop coolant loss which may be due to a cracked head. The crack develops across the #6 intake valve spring seat area and continues across and behind the #4 and #5 exhaust valve spring seat.. With the aid of dye check, the crack is visible to the unaided eye (see illustration).
