Specifications: Other Toyota Prius I рестайлинг

PRIUS

The following service precautions must be followed

Scheme 1

1. Ensure ignition is off and ignition key is removed from ignition before performing any inspection or service procedure in engine compartment, as engine may automatically start and shut off when ignition is on and READY light is illuminated. READY light is displayed just above the shift lever position indicator on instrument cluster at center of instrument panel.
2. Read all service and warning labels in engine compartment before performing any procedures in engine compartment.
3. All high-voltage wiring harness connectors contain Orange connectors. DO NOT touch any wiring harness that contains Orange connectors.
4. High-voltage battery and other high-voltage components may be identified by HIGH VOLTAGE caution labels on them. DO NOT touch these components.
5. If necessary to inspect or service high-voltage system, ensure ignition is off. Remove service plug and wait at least 5 minutes to ensure high voltage is fully discharged before touching any high-voltage wiring harness, connectors or components. Service plug is located on service plug assembly at driver's side front corner of trunk compartment, near high-voltage battery. (Scheme 1) Ensure service plug is stored in a location in which no one may install service plug while technician is working on the vehicle.
6. If necessary to touch any high-voltage wiring harness, connectors or components, ensure service plug is removed and battery voltage or less exists at electrical connector. Use Toyota insulated gloves when touching any high-voltage wiring harness, connectors or components. Ensure insulated gloves are dry and in good condition and that no holes exist in insulated gloves by applying air to insulated glove before touching any high-voltage wiring harness, connectors or components.
7. DO NOT wear any metal objects while working on vehicle which may accidently drop and cause a short circuit.
8. If any high-voltage wiring harness connector is disconnected, ensure terminal on wiring harness connector is wrapped with tape to prevent wiring harness connector from contacting any surface.
9. If servicing high-voltage system, place sign on roof of vehicle to indicate to other technicians that high-voltage system is being serviced.

COOLING SYSTEM BLEEDING

Note. On Celica, MR2 and Prius, whenever cooling system is drained, special cooling system bleeding procedure must be performed. On all other models, no special cooling system bleeding procedure is required.

Celica

1. This procedure assumes cooling system has been completely drained by loosening radiator drain plug on bottom of radiator and engine drain plug on coolant drain union located on driver's side rear corner of cylinder block.
2. Remove front fender apron seal and upper radiator support seal for access to coolant reservoir. Remove coolant reservoir bolts and coolant reservoir hose retaining clamp bolts. Raise and support coolant reservoir and secure to hood latch assembly.
3. Remove cooling system bleeder plug. This is a thumb-type plug on top of coolant reservoir, near coolant reservoir cap. Add approximately 4 qts. (3.7L) of 50/50 mixture of distilled water and coolant to coolant reservoir until coolant level is at FULL mark on coolant reservoir. DO NOT use plain water or alcohol based coolant. Continue to add water/coolant mixture as necessary. If cooling system does not require approximate refill capacity to maintain coolant in coolant reservoir at the FULL mark, air exists in system or system was not properly drained. See «COOLING SYSTEM APPROXIMATE REFILL CAPACITY (CELICA)»(ref-129026-S23906679852002051000000) table.
4. If cooling system will not take additional coolant, squeeze lower radiator hose several times while using your finger to block cooling system bleeder plug opening. Continue to do this while slowly adding coolant. Start engine with coolant reservoir cap and cooling system bleeder plug removed. Ensure A/C is turned off. Operate engine until cooling fan comes on and goes off one time. Add additional coolant to coolant reservoir as necessary.
5. Install cooling system bleeder plug. Install and tighten coolant reservoir cap about 2 1/2 turns until "click" sound is heard. Increase engine speed to 3000 RPM for 5 seconds and then allow engine to idle for 5 seconds. Repeat this procedure for at least 15 minutes. Shut engine off and allow engine to completely cool. With engine completely cooled, coolant level in coolant reservoir should be between LOW and FULL marks. The next time engine operates and is at normal operating temperature, coolant level in coolant reservoir should be above the FULL mark.
6. Reinstall coolant reservoir, front fender apron seal and upper radiator support seal. Check for coolant leaks. COOLING SYSTEM APPROXIMATE REFILL CAPACITY (CELICA) Engine Application Qts. (L) 1.8L 1ZZ-FE A/T 5.9 (5.6) MT 6.0 (5.7) 1.8L 2ZZ-GE A/T 6.1 (5.8) M/T 6.2 (5.9)

Scheme 3

1. Remove spare tire, tool box and luggage compartment trim cover. (Scheme 2) Connect air bleed hoses to heater coolant valve air drain plug and radiator air drain plug. (Scheme 3) Suspend opposite end of air bleed hoses from the hood. Ensure air bleed hoses are not pinched or restricted. Rotate heater coolant valve air drain plug and radiator air drain plug counterclockwise to open position.
2. Slowly add a 50/50 mixture of distilled water and coolant to coolant reservoir so that coolant lever in coolant reservoir remains at least 1/2 full all the time while adding coolant to coolant reservoir. Coolant reservoir is located at driver's side rear corner of engine compartment. (Scheme 3) DO NOT use plain water or alcohol based coolant. Approximate capacity is 11.0 qts. (10.4L). Air should bleed from air bleed hoses on heater coolant valve air drain plug and radiator air drain plug. Ensure coolant level in both air bleed hoses and coolant reservoir are at the same level. (Scheme 3)
3. If coolant level in air bleed hoses is lower than level at coolant reservoir, air still exists in cooling system. Check for pinched or restricted air bleed hoses and repeat step 2. When proper coolant level is obtained in air bleed hoses, close heater coolant valve air drain plug and radiator air drain plug. Install cap on coolant reservoir until "click" sound is heard and cap is in the lock position. Remove air bleed hoses.
4. Start engine and ensure air is bleeding into coolant reservoir. Warm engine to normal operating temperature. Check that coolant level in coolant reservoir is above the FULL mark. Shut engine off and allow engine to completely cool. Ensure coolant level in coolant reservoir is between LOW and FULL marks. Add coolant if necessary. Reinstall luggage compartment trim cover, tool box and spare tire.

Scheme 4

1. Slowly add a 50/50 mixture of distilled water and coolant to radiator. DO NOT use plain water or alcohol based coolant. Approximate capacity is 5.2 qts. (4.9L).
2. Install radiator cap. Start engine and allow engine to idle. Accelerate engine and then engine allow to idle. Repeat this procedure several times for approximately 2 minutes. Shut engine off. Remove radiator cap and check coolant level. Coolant level should be even with rim of radiator filler neck. If coolant level decreases when pinching the upper or lower radiator hose closed several times, add coolant as necessary. Once correct coolant level is obtained, install radiator cap and go to next step.
3. It is necessary to put transit in inspection mode so engine will run continuously. To put transit in inspection mode, perform the following steps within 60 seconds: Ensure ignition is off and then turn ignition on. Ensure transaxle is in Park and then fully depress accelerator pedal 2 times. Place transaxle in Neutral and then fully depress accelerator pedal 2 times. Place transaxle back in Park and then fully depress accelerator pedal 2 times.
4. Check that master warning light on instrument cluster at center of instrument panel is flashing to indicate inspection mode operation. (Scheme 4) Master warning light may also be referred to as hybrid system error warning light.
5. Start engine and operate engine until cooling fan starts to turn with engine speed less than 2500 RPM. Shut engine off immediately after cooling fan starts to turn. Allow engine to cool until engine coolant temperature is less than 122°F (50°C). Remove radiator cap and recheck coolant level.
6. If proper coolant level exists, shut engine off. Go to next step. If coolant level has dropped, add coolant and repeat steps 3 - 6. Once proper coolant level exists, shut engine off. Go to next step.
7. Air must be bleed from heater water pump which circulates coolant through the heater core. The heater water pump may also be referred to as water pump motor (A/C). Turn ignition on with engine off. Place blower speed control dial in LO position and temperature control dial to MAX HOT position. Operate heater water pump until constant coolant flow sound exists at heater core. Ensure there is no sound of air in the coolant flow. Once constant sound of coolant flow exists through heater core, fill coolant reservoir to the maximum level.
