Pre-delivery Inspection Orlando ENGINE COMPARTMENT

SECTION 2

ENGINE COMPARTMENT

1. COMPONENTS CONNECTION LOOSE

Check engine compartment for components which may be loose; kinked or pinched vacuum hoses or electrical connections, and for any other missing or disconnected components as below.

Air Cleaner
Engine oil filter cap
Brake fluid reservoir*
Clutch fluid reservoir*
Coolant reservoir
fuse and relay box
battery
Washer fluid reservoir
Power steering fluid reservoir
Engine oil level dipstick

Check engine components for missing or disconnection.
Check electrical connections for loose or misconnection.
Check vacuum hoses for kink, pinch, damage, twist and swelling.
Check hose clamps and pipe connections for leakage or looseness for following systems.

– Fuel system
– Cooling system
- Power steering system
– Air-conditioning system

Check engine components which may be loose.

If remedy is required, tighten clamps, connections, bolts and nuts, and replace or repair defective hose and its connections.

2. HOSE AND ELECT. WIRES ROUTING

Check to assure that following hoses and electrical wires are properly routed to provide sufficient clearance with adjacent moving or hot parts.

Fuel hose
Air-conditioning hose
Vacuum hoses
High-tension cable for ignition system
Electric wires

3. FREENESS OF MOVEMENT OF LINKAGE, VALVES AND OTHER COMPONENTS

Observe the movement or freeness of movement of valves and other components.

Clutch pedal

Check the clutch pedal free play when depress the clutch pedal.

Steering linkage system

The best method for checking condition is with the vehicle on a flat surface and two mechanics working as a team.
One of the mechanics turns the steering wheel one way and then the other, and checks its function mounting and condition, also the mounting for the steering column (with or without power assistance) while the other mechanic checks for play in the following places;

– Track rods (there must be no looseness)
– Steering gear mounting on frame
– Steering shaft universal joints from steering gear and upwards (there must be no looseness)
– Check all clamps for proper mounting and tightness

Starter motor assembly

1) Check that starting switch and contacts are securely fitted.
2) Run starter motor, and check following.

Starter motor should crank engine at normal speed.
Starter motor should function without abnormal noise.

Note : Do not run the starter motor too long as this puts a severe strain on the battery.

Engine starting response

Starting the engine, and check if the engine will function normally.
If the engine does not start or if it stops again, check following items. For further information, refer to service manual.

– Ignition system
– IAC operation
– Sensors and ECM, if necessary

4. UNUSUAL NOISES

Check for unusual noises within engine compartment.

Run the engine and check if there are some unusual noises. If unusual noises are heard, fasten or fix the loosen parts and adjust the clearance between components.

5. SEEPAGE AND LEAKS AT HOSES AND PIPE CONNECTIONS, ETC.

Visually inspect for seepage and leaks at hoses and pipe connection, seals, gaskets and plugs. Tighten clamps and connection as necessary.

Fuel system
Air-conditioning system
Cooling System
Brake system
Clutch system
Power steering system
Engine assembly

– Camshaft support housing
– Cylinder head
– Cylinder block
– Sump
– Seals for camshaft etc.

6. POWER STEERING SYSTEM

Check power steering gear, lines and hoses for leaks and clearance with adjacent panels, moving or hot parts.

Tighten clamps and connectors as necessary.

7. ENGINE COOLANT PROTECTION

Test engine coolant protection

The cooling fans are actuated by the ECM using a low-speed cooling fan relay and a high speed cooling fan relay on non-A/C model or a series/parallel cooling fan relay on A/C model as below;

<Example: TACUMA(REZZO)>

Description	Cooling fan Operating Mode	Fan operating Temp.(°C)
Description	Cooling fan Operating Mode	ON	OFF
A/C OFF or Non-A/C model	Low speed	96	93
A/C OFF or Non-A/C model	High speed	100	97
A/C ON	Low speed	when the A/C system id ON
A/C ON	High speed	100	97

Check all hoses and connections.
Check for leaks of cooling system as per following procedure.

– Correct coolant level and run engine at idle speed.
– Mount radiator tester on expansion tank instead of screw cap.
– Leaks can be recognised by escaping coolant.
– If pressure drops or even rises without coolant escaping, this indicates an internal coolant leak in the engine caused by a defective cylinder head gasket or a crack in the block.

8. ALL FLUID LEVELS CHECK

Check all fluid levels; engine oil, transmission oil, power steering oil, brake and cooling system.

Engine oil

– Engine oil level should be checked with the vehicle standing on level ground (before the operation of engine). If the engine is running, stop the engine and wait 5 minutes for the oil to drain back to the sump before checking the oil level.
– Pull out the oil level indicator (dipstick), wipe and clean it, and reinsert it.
Again pull it out and check that the oil level is within MAX. and MIN. level marks. Also check the oil on the dipstick for contamination.
– The oil should not go above the "Max" mark on the dip-stick, since this may cause engine damage.

Note : Removal of the fluid level plug when the transaxle fluid is hot may cause injury if fluid drains from the fluid level plug.

Note : Use only special fluids as specified in the Owner's Manual.

Brake/clutch fluid

– The fluid level in the container should be between the MIN and MAX marks.
– If the level falls below the MIN mark, add the fluid to the MAX mark and tighten the cap securely afterwards.

Note : Fluid specification DOT 4 or DOT 4Plus

Coolant

Check the coolant level in surge tank.
– The coolant should be full in the radiator and the fluid level should be between the "MIN" and "MAX" marks on the outside of the surge tank when the engine is cool.

Note : Do not overfill and remove the coolant surge tank cap when the engine and radiator are hot.

Note : The anti-freeze content of the coolant should be maintained at a minimum of 50% and maximum of 60%.

Note : Only use coolant that is specified in the Owner's Manual.

Windscreen washer fluid

Check the windscreen washer fluid level in the reservoir tank.
– Windscreen washer level in the reservoir tank should be at 2/3-3/4 level.

Note : Do not use radiator anti-freeze for windscreen washer solution. Because this may result in damage to the paint work.

Power steering oil

Check fluid level with engine turned off.
– The fluid level should be between the MIN and MAX marks on the reservoir.
If it drops to or below the MIN mark, top up with the specified fluid.

Note : Fluid specification DEXRON® VI

9. BELTS TENSION

Check whether the belt is worn, cracked or frayed.
check tension for following belts and adjust if necessary.

Note : to check belt tension easily, apply moderate thumb pressure (Approx. 10 Kg) midway between pulleys, and check the deflection. If the belt goes down by 10 mm, it is normal.
