This document provides instructions for adjusting the valve clearance on a 2000-01 Chevrolet Prizm with a 1.8L 4-cylinder engine. The procedure involves rotating the crankshaft to specific positions and checking clearance between the camshaft lobe and adjusting shim using a feeler gauge. If clearance is outside specifications, the adjusting shim is replaced. Charts are provided to select the correct shim thickness.

VALVE CLEARANCE ADJUSTMENT
1. Disconnect negative battery cable. Disconnect all necessary control cables, hoses and
electrical connections. Remove valve cover and gasket.
2. Rotate crankshaft so cylinder No. 1 is at TDC of compression stroke. Valve lifters on
cylinder No. 1 should be loose and valve lifters on cylinder No. 4 should be tight. If they are
not, rotate crankshaft one revolution. Ensure timing mark on crankshaft pulley aligns with
"0" mark on timing belt cover.
3. Using feeler gauge, check clearance between camshaft lobe and adjusting shim for the
following: all valves on cylinder No. 1, intake valves on cylinder No. 2 and exhaust valves
on cylinder No. 3. Record all readings.
4. Rotate crankshaft 360 degrees. Check clearance between camshaft lobe and adjusting shim
for the following: all valves on cylinder No. 4, intake valves on cylinder No. 3 and exhaust
valves on cylinder No. 2. If clearance is not within specification, adjust by replacing
adjusting shim. See VALVE CLEARANCE SPECIFICATIONS table.
