2000 TOYOTA CAMRY coolant

NEW FEATURES Ð 5S-FNE ENGINE 16
6. Fuel Filter
Mounted below the vehicle floor, the fuel filter re-
moves any moisture or oil from the fuel.
7. Fuel Pressure Regulator
The fuel pressure regulator regulates the fuel pressure by reducing the pressure of the compressed natural
gas from the fuel tank to the fuel injection pressure, which is 8 km/cm
2 (114 psi, 785 kPa).
Similar to the fuel shutoff valve for the fuel tank, a fuel shutoff valve is provided on the fuel inlet side
of the fuel pressure regulator to shut off the supply of fuel when the engine is stopped or during abnormal
conditions.
An oil separator that traps the moisture and oil in the fuel is provided on the low pressure side.
A built-in relief valve is provided to protect the parts located on the low pressure side.
While the fuel pressure is being reduced by the fuel pressure regulator, the Joule-Thomson effect associat-
ed with the expansion of the gas causes the fuel pressure regulator to be cooled excessively, exerting
unfavorable influence on the rubber parts such as diaphragms and fuel hoses.
Therefore, to raise the gas temperature, a water passage is provided in the fuel pressure regulator to
allow the engine coolant to warm the regulator.

TOYOTA MAINTENANCE & REPAIR SUPPORT13

SCHEDULED MAINTENANCE LOGS21 Brake Linings/Drums and Brake Pads/Discs
Check the brake linings (shoes) and drums for scoring, burning,
fluid leakage, broken parts and excessive wear. Check the pads for
excessive wear and the discs for runout, excessive wear and fluid
leakage. A qualified technician should perform these inspections.
Charcoal Canister (CA, MA and NY vehicles)
Check for internal damage and clogging. If necessary, clean
with compressed air or replace. A qualified technician should
perform these operations.
Differential Oil
Inspect each component for signs of leakage. If you discover any
leakage, have it repaired by a qualified technician immediately.
Drive Belts
Inspect for cracks, excessive wear and oiliness. Check the belt ten-
sion and adjust if necessary. Replace the belts if they are damaged.
Drive Shaft Boots
Check the drive shaft boots and clamps for cracks, deteriora-
tion and damage. Replace any damaged parts and, if necessary,
repack the grease. Selected models also require periodic inspec-
tion of the flange bolts for proper torque. A qualified technician
should perform these operations.
Engine Air Filter
Check for damage, excessive wear and oiliness. Replace if necessary.
Engine Coolant
Drain and flush the cooling system and refill with an ethylene-
glycol type coolant. A qualified technician should perform
this operation.
Engine Oil and Oil Filter
Change the oil filter and replace the engine oil with API SH,
Energy- Conserving II multigrade or ILSAC multigrade oil.
For recommended viscosity, refer to your
Owner’s Manual.
