TURBO CHARGER
Turbocharger Boost Control Actuator
lConnect the handy vacuum pump (B) to the turbocharger boost
control actuator (1), and make sure that the rod (2) strokes
smoothly in compliance with the following pressure.
lPressure to be applied at the turbocharger boost control actua-
tor (1) part to move rod (2) end as follows:
TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
lMake sure that the engine oil level is between MIN and MAX of the oil level gauge. (When engine oil
amount is more than MAX, engine oil flows into the inlet duct through blow-by gas passage, and turbo-
charger is misjudged malfunction.)
lAsk the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.
lReplace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.
lIf no malfunction is found after the unit inspections, judge that the turbocharger body has no malfunction.
Check the other parts again.
A: Large possibility
B: Medium possibility
C: Small possibilityA : Dial gauge

the figure.
6. Rotate exhaust manifold.
INSPECTION AFTER REMOVAL
Surface Distortion
lUse a reliable straight edge and feeler gauge to check the flat-
ness of exhaust manifold fitting surface.
lIf it exceeds the limit, replace exhaust manifold.
INSTALLATION
lIf stud bolts were removed, replace them with new ones, and tighten them to the specified torque:
lTighten the exhaust manifold mounting nuts in the following procedure:
1. Install gasket so that the alignment protrusion faces the No. 4 port. Refer toEM-34, "
Removal and Instal-
lation".
2. Tighten the nuts in order specified in the figure.
3. Re-tighten the nuts 1 to 8.
4. Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Start engine and raise engine speed to check no exhaust gas and engine oil leaks.

Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
lBefore starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*1: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
*2: Check engine oil level 10 minutes after engine stopped.
