7. Clean both balancer shaft No. 2 journals and the
bearing halves with a clean shop towel, then install
the balancer shafts into the lower balancer shaft
holder.
8. Place one strip of plastigage across each No. 2 journal.
9. Reinstall the bearings and the upper balancer shaft holder, then tighten the bolts.
NOTE: Do not rotate the balancer shafts during inspection.
 After torquing, tighten the three 8 mm bolts extra 16 ° (K20Z3 engine). 10. Remove the upper balancer shaft holder and the
bearings again, and measure the widest part with
the plastigage. If the balancer shaft No. 2 journal oil
clearance is out-of-tolerance, install new bearings,
and recheck. If it is still out-of-tolerance, replace the
balancer shafts.
11. Align the punch mark on the rear balancer shaft in the center of the two punch marks on the front
balancer shaft, then install the balancer shafts on
the lower balancer shaft holder.

1. Wait until the engine is cool, then carefully removethe radiator cap (A). Wet the radiator cap seal with
engine coolant, then install it on a commercially
available pressure tester (B).
2. Apply a pressure of 93 123 kPa (0.95 1.25 kgf/cm , 14 18 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap. 1. Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the base of the filler neck.
2. Attach a commercially available pressure tester (A) to the radiator, and apply a pressure of 93 123 kPa
(0.95 1.25 kgf/cm , 14 18 psi).
3. Inspect for engine coolant leaks and a drop in pressure.
4. Check for engine oil in the coolant and/or coolant in the engine oil.
5. Remove the tester, and reinstall the radiator cap.
