4.6. Pump of cooling liquid

GENERAL INFORMATION

Pump of cooling liquid

Three small shooters specified openings for fastening bolts, and two big shooters specified control openings.

Check

PERFORMANCE ORDER
1. Failure of the pump of cooling liquid involves serious damages because of an engine overheat.
2. Before check warm up the engine. On the working engine press the top hose of a radiator and gradually release. At the serviceable pump the liquid pressure in a hose has to be felt.

Prevention

Do not bring a hand close to fan blades.


3. The control opening for a liquid drain is provided in the pump. At failure of an epiploon of the pump through a control opening (see rice. The pump of cooling liquid) follows cooling liquid. To find an opening it is necessary to illuminate space behind the conducted pump flange, directly under shaft.
4. At destruction of bearings of the pump in forward part of the engine the howling sound will be listened. Wear of bearings can be defined shaking the pump up and down. Also the sliping drive belt therefore, on a characteristic sound it is possible to draw a wrong conclusion on malfunction of the pump can make a sound, close on a tonality. To exclude a sound from a belt put with dispersion special structure for automobile driving belts.

Removal

PERFORMANCE ORDER
Engine 4E-FE
1. Disconnect the battery from weight and merge cooling liquid (see subsection 2.8.4).
2. Remove the generator, being guided by the description in subsection 3.3.11.
3. Turn off a nut and two bolts of fastening of a rack of the soaking-up collector in back part of the engine and remove a rack.
4. Disconnect inlet and perepuskny hoses from a branch pipe from an inlet branch pipe of the pump in back part of the engine. Turn off bolts of fastening and remove an inlet branch pipe from the pump, remove ring laying from a branch pipe end face.
5. Pick up the phone of the index of level of oil. Turn off a bolt of fastening of a tube of the index of level of oil and an adjusting arm of the generator to the engine, get a tube from the case of the oil pump.
6. Turn off bolts and two nuts of fastening of the pump to the block of cylinders and remove the pump of cooling liquid in collecting (the pulley can remain on a pump shaft).
7. Disassemble the pump and replace laying. Carefully clear all demountable planes of the pump of the remains of material of laying. Collect the pump, having established new laying.
Engines 4A-FE and 7A-FE
8. Disconnect the battery from weight and merge cooling liquid (see subsection 2.8.4).
9. Being guided by the description in subsection 2.6.4, take off belts of the drive of the pump of the hydraulic booster, generator and water pump and compressor of the conditioner. Then remove the top arm of the hydraulic booster.
10. Being guided by the description, uncover heads of cylinders (see subsection 3.1.1.3) and the top covers of a gear belt (see subsection 3.1.1.6).
11. Pick up the phone of the index of level of oil. Take aside a screw-driver the holder of conducting from an arm of a tube of the index of level of oil. Turn off a bolt of fastening of a tube of the index of level of oil to the engine and get a tube from the case of the oil pump.
12. Turn off two nuts of fastening of the right branch pipe of cooling liquid to a head of cylinders which are behind the pump, disconnect the socket from the sensor of temperature of cooling liquid (it is specified by an arrow) on a branch pipe.
13. Working from above, turn off two nuts of fastening (a small arrow) of a branch pipe to a head of cylinders, turn off the top bolt of fastening of the pump (a big arrow).
14. Working from below the car, turn off two other bolts of fastening of the pump to the block of cylinders. Not to turn off the bolts fastening two covers of the pump before full removal of the pump assembled from the block of cylinders. Remove the pump of cooling liquid assembled with a branch pipe (the pulley can remain on a pump shaft).

15. Disassemble the pump (see rice. The pump of cooling liquid) also replace laying. Carefully clear all demountable planes of the pump of the remains of material of laying, get ring laying and clear a flute. Collect the pump, having established new laying.

Installation

PERFORMANCE ORDER
Engine 4E-FE
1. Apply a sealant strip (which should be got at the dealer) about 3 mm wide on a sealing flute in a pump housing, being guided by the instruction attached to sealant.
2. Install the assembled pump on the block of cylinders and fix a bolt and two nuts.
3. Establish other details upside-down. At installation of a tube of the index of level of oil replace a sealing ring in a tube entrance place to the oil pump. Replace also a ring on an inlet branch pipe of the pump.
4. After the end of assembly wait not less than two hours that is necessary for sealant hardening, then fill in liquid in the cooling system (see subsection 2.8.4), start the engine and check existence of a leak and operation of the engine.
Engines 4A-FE and 7A-FE
5. Install the assembled pump on the block of cylinders, previously having replaced a sealing ring. Replace laying of a branch pipe of the pump.

Prevention

If the pump is replaced new in connection with big run, it is necessary to replace also the hose connecting a branch pipe of the pump and an inlet branch pipe of the engine.


6. Establish other details upside-down. At installation of a tube of the index of level of oil replace a sealing ring in a tube entrance place to the oil pump.
7. Fill in liquid in the cooling system (see subsection 2.8.4), start the engine and check existence of a leak and operation of the engine.
