Rodeo LS 4WD V6-3.2L (1998)
Valve Clearance: Adjustments
BULLETIN NUMBER: SB99-01-S002
V6 VALVE ADJUSTMENT
AFFECTED VEHICLES
1998-2000 VehiCROSS (VX) / Trooper
(UX) / Rodeo (UE) / Amigo (UA) V6 models
with "direct-attack" valvetrain.
For the above affected vehicles, periodic 60,000 mile valve clearance inspections are not required. Adjust if valve noise is evident or a rough idle
condition exists.
NOTE:
When checking valve clearances, adjustment is required only when the clearance (lash) is out of specification. Be sure to retorque the camshaft
bearing cap bolts before checking and adjusting the valve clearance.

NOTE:
- Valve adjustment can be done either on-vehicle or off-vehicle.
- To measure exhaust valves, you need a 0.25 mm and a 0.35 mm feeler gauge.
- To measure intake valves, you need a 0.23 mm and a 0.33 mm feeler gauge. Since these are odd sizes, you may need to stack two gauges (for example,
0.11 mm and 0.12 mm to make 0.23 mm). If you do this, make sure the gauges are clean and in good condition. If you're not sure the gauge stack is
correct, measure it with a micrometer.
On-Vehicle Valve Adjustment
1. Make a copy of the Valve Inspection Chart.
2. Make a copy of the Valve Shim Replacement Chart, then tape the pages together, side-by-side.
3. Remove the cylinder head covers.
4. Measure the valve clearances using the Go/No-Go method (see the note below). The clearances must be
-
Intake valves: 0.25 mm +/- 0.05 mm
-
Exhaust valves: 0.30 mm +/- 0.05 mm
