Cylinder Compression Pressure Test
•
The result of a cylinder compression pressure test
can be utilized to diagnose several engine malfunc-
tions.
• Ensure the battery is completely charged and the
engine starter motor is in good operating condition.
Otherwise the indicated compression pressures
may not be valid for diagnostic purposes.
Check engine oil level and add oil if neces-
sary.
Disconnect the spark plug wires.
Remove all spark plugs from engine (as spark plugs are being removed, check electrodes for
abnormal firing indicators fouled, hot, oily,
etc.).
Record cylinder number of each spark plug for future reference.
Disconnect fuel injector electrical connectors.
Be sure throttle blade is fully open during the compression check.
Insert compression pressure adaptor or the equivalent into each spark plug hole in cylinder head.
Crank engine until maximum pressure is reached on gauge. Record each cylinder pressure.
Compression should not be less than 880 kPa and not vary more than 25 percent from cylinder to cylinder.
If one or more cylinders have abnormally low compression pressures, repeat the compression test.
If the same cylinder or cylinders repeat an abnormally low reading on the second compression test, it could indicate the existence of a problem with the cylinder in question.
NOTE :
The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine
should not be disassembled to determine the cause of low compression unless some malfunction is present.

Operation
The primary purpose of a cooling system is to maintain engine temperature in a range that will provide satisfactory
engine performance and emission levels under all expected driving conditions. It also provides hot coolant for heater
performance and cooling for automatic transmission oil. This is done by transferring heat from engine metal to cool-
ant, moving the heated coolant to the radiator, and then transferring the heat to the ambient air. Engine Coolant Flow Diagram - 1.6L & 1.8L & 2.0L

Cooling System Pressure Test
WARNING!
Always allow the engine to cool before opening the cooling system. Do not remove the coolant pressure relief
cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and
hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may
result in serious personal injury.
CAUTION:
Do not pressurize the cooling system beyond the maximum pressure listed in the specifications
table in this section, or cooling system components can be damaged.
1. Turn the engine off.
2. Check the engine coolant level. Adjust the coolant level as necessary.
3. Attach the pressure tester to the coolant recovery reservoir. Install a pressure test pump to the quick-connectfitting of the test adapter.
4. Pressurize the engine cooling system to 111 kPa. Observe the gauge reading for approximately 2 minutes. Pres- sure should not drop during this time. If the pressure drops within this time, inspect for leaks and repair as nec-
essary.
5. If no leaks are found and the pressure drops, the pressure relief cap may be leaking. Install a new pressure relief cap and retest the system.
6. If no leaks are found after a new pressure relief cap is installed, and the pressure drops, the leak may be inter- nal to the radiator transmission cooler (if equipped). Inspect the coolant for transmission fluid and the transmis-
sion fluid for coolant. Repair as necessary.
7. If there is no contamination of the coolant or transmission fluid, the leak may be internal to the engine. Inspect the coolant for engine oil and the engine oil for coolant.
8. Release the system pressure by loosening the pressure relief cap. Check the coolant level and adjust as nec- essary.
Cooling System Concentration Test
CAUTION:
Do not mix types of coolant, corrosion protection will be severely reduced.
Coolant concentration should be checked when any additional coolant is added to the cooling system or after a cool-
ant drain, flush and refill. The coolant mixture offers optimum engine cooling and protection against corrosion when
mixed to a freeze point of -37°C to -46°C. The use of a hydrometer or a refractometer can be used to test coolant
concentration.

Description
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the
handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,
good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and type
of equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front Axle
•Camber
• Caster
• Toe-in
Rear Axle
• Camber
• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb
height specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on the
vehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height Measurement
The wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb height
specification.
• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.
• The tires are to be inflated to the recommended pressure.
• All tires are to be the same size as standard equipment.
• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
• Vehicle height is not adjustable.
• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.
• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.
• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :
Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-
pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,
moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper at
the bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions an
equal number of times.
Pre-Wheel Alignment Inspection
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-
rections must be made to the vehicle to ensure proper alignment. 1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip- ment.

Refrigerant System Leaks
WARNING!
R-134a service equipment or vehicle A/C systems should not be pressure tested or leak tested with compressed
air. Mixture of air and R-134a can be combustible at elevated pressures. These mixtures are potentially danger-
ous and may result in fire or explosion causing property damage, personal injury or death. Avoid breathing A/C
refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved service
equipment meeting SAE requirements to discharge an R-134a system. If accidental system discharge occurs,
ventilate work area before resuming service.
NOTE :
If the A/C refrigerant system charge is empty or low, a leak in the A/C system is likely. Inspect all A/C lines, fittings
and components for an oily residue. Oil residue can be an indicator of an A/C system leak location.
NOTE :
The only way to correctly determine if the refrigerant system is fully charged with R-134a is to completely evacuate
and recharge the A/C system.
Refrigerant System Empty
1. Evacuate the refrigerant system to the lowest degree of vacuum possible. Determine if the system holds a vac- uum for 15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum level,
proceed to STEP 2.
2. Prepare and dispense 0.3 kilograms of R-134a refrigerant into the evacuated refrigerant system and proceed to STEP 1 of the System Low procedure.
Refrigerant System Low
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
2. Operate the heating-A/C system with the engine at idle under the following conditions for at least 5 minutes:Doors or windows open, transaxle in Park or Neutral with the parking brake set (depending on application), A/C-
Heater controls set to outside air, full cool, panel mode, high blower and with A/C compressor engaged.
3. Shut the vehicle Off and wait2-7minutes. Then use an electronic leak detector that is designed to detect R-134a refrigerant and search for leaks. Fittings, lines or components that appear to be oily usually indicate a
refrigerant leak. To inspect the A/C evaporator for leaks, insert the leak detector probe into the drain tube open-
ing or an air outlet. A dye for R-134a is available to aid in leak detection. Use only approved refrigerant dye.
CAUTION:
A leak detector only designed for R-12 refrigerant will not detect leaks in an R-134a refrigerant sys-
tem.
