Check of serviceability of functioning, removal and installation of electric components of a chain of management of system of cooling of the engine

The sensor of temperature of cooling liquid (ECT)

Check

For performance of this check the special diagnostic equipment and its performance is required it will be more correct to charge to specialists of car-care center.

Removal

Petrol models

 PERFORMANCE ORDER

  1. Empty cooling system (see. Head Routine maintenance).

Models with SOHC engines

 PERFORMANCE ORDER

  1. Remove an air purifier and the air line laid to the right of the engine (see. Head of the Power supply system and release).
  2. Disconnect conducting from the sensor located on the inlet pipeline behind the generator.
  3. Turn out the sensor and remove it from the inlet pipeline. Remove a sealing ring, - at installation it is subject to replacement without fail.

Models with engines 1.4 and 1.6 of l of DOHC

 PERFORMANCE ORDER

  1. Remove an air purifier assembled with an air line (see. Head of the Power supply system and release).
  2. Disconnect electroconducting from the sensor of temperature established in the case of the thermostat on the right on the engine.
  3. Turn out the sensor from the case of the thermostat and remove it from the car.

Models with engines of 1.8 l

 PERFORMANCE ORDER

  1. Remove the thermostat case (see. Removal, installation and check of serviceability of functioning of the thermostat).
  2. Turn out and remove the temperature sensor.

Models with engines of 2.0 l

 PERFORMANCE ORDER

  1. Remove from the thermostat case the ignition module.
  2. Disconnect from the sensor electroconducting.
  3. Turn out the sensor and remove it from the case of a thermostat / flange of cooling.

Diesel models

Models with engines of 1.7 l

The sensor of temperature is on the thermostat case in right (SOHC engines) / left (DOHC engines - see an illustration) parts of a head of cylinders.


 PERFORMANCE ORDER

  1. Cock the parking brake, поддомкратьте a front of the car and establish it on props. At the corresponding complete set remove protection of a case. Get under the sensor suitable drain capacity for collecting spilled cooling liquid.
  2. Wait complete cooling of the engine, unscrew a cover of a broad tank, then establish it back and hardly tighten, is should help to minimize liquid losses at sensor removal. Pick up a suitable cap for an opening blockage under sensor installation.
  3. Remove a protective casing of the engine.
  4. Disconnect electroconducting from the temperature sensor, liberate it from intermediate clamps and separate from the thermostat case. For the purpose of minimization of losses of cooling liquid at once screw in an opening the new sensor, or the cap prepared in advance.

Models with engines of 2.0 l

On all engines of 2.0 l the sensor of temperature is located from above on the thermostat case, in the right part of a head of cylinders.

Dismantle of the sensor is made in the manner similar described above for models, 1.7 l completed with engines (see above Models with engines of 1.7 l).

Installation

All models

Installation is made as it should be, the return to an order of dismantle of components. Do not forget to replace a sealing element / to grease with hermetic a carving part of the sensor. The tightening of the sensor should be made with demanded effort.

In summary correct level of cooling liquid (see. Head Routine maintenance) also check the sensor on existence of signs of development of leaks.

The sensor switch of level of cooling liquid

Removal and installation

All models

The sensor is established in the bottom of a broad tank.

 PERFORMANCE ORDER

  1. Wait complete cooling of the engine, and unscrew a cover of a broad tank for dumping of residual pressure.
  2. Liberate a tank from basic arms, remove it and merge cooling liquid in suitable capacity.
  3. Disconnect electroconducting and remove the sensor switch from a tank.
  4. Installation is made upside-down.

Module of management of system of cooling

Removal and installation

All models

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery (see. Head engine Electric equipment) also take him aside from the polar plug.
  2. Remove a front bumper (see. Head Body).
  1. The module is established at the left under a forward spoiler. Extend outside of a latch of clamps and disunite two contact sockets of electroconducting of the module.
  1. Turn out fixing bolts and remove the module from a forward spoiler.
  2. Installation is made upside-down.
