Removal, installation and check of serviceability of functioning of the thermostat

Do not open a cover of a radiator and do not remove the thermostat before full cooling of the engine!

Removal

Petrol models

Models with engine SOHC

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Empty cooling system (address to the Head of Adjustment and car routine maintenance).

If be not going to fill in a new liquid in system, keep merged for the subsequent use.

  1. Remove assemblage of an air cleaner with air lines (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases).
  2. Ослабьте fixing collars also disconnect the top hose of a radiator from a cover established on the right on a head of cylinders of the thermostat.
  3. Uncover cases GRM, a belt of drive ГРМ with an intermediate roller, a cogwheel of a camshaft and a back cover of drive ГРМ.
  4. Remove from the case of the thermostat hose ОЖ, turn out fixing bolts and uncover the thermostat. The thermostat is sideways at a head of cylinders, under a camshaft cogwheel.

Bolts of fastening of a cover of the thermostat

  1. Take the thermostat from the case, remove a sealing ring, - try to remember adjusting position of components.

Models with engine DOHC

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery (see the Head of System of an electric equipment of the engine).
  2. Empty cooling system (address to the Head of Adjustment and car routine maintenance).

If be not going to fill in a new liquid in system, keep the merged liquid for the subsequent use.

  1. On engines of 1.0 and 1.2 l remove an air inlet sleeve. Establish capacity under a branch pipe of a cover of the thermostat.
  2. Ослабьте fixing collars also disconnect the top hose of a radiator from a thermostat cover.
  3. Turn out fixing bolts and remove the case together with the thermostat built in it. On engines of 1.4 and 1.6 l remove a sealing ring.

Removal of a sealing ring of the thermostat

Diesel models

 PERFORMANCE ORDER

  1. Remove the storage battery with a basic arm (see the Head of System of an electric equipment of the engine).
  2. Cock a lay brake, поддомкратьте the car and establish it on props. At a corresponding complete set remove protection картера.
  3. Empty cooling system (address to the Head of Adjustment and car routine maintenance).

If be not going to fill in a new liquid in system, keep merged for the subsequent use.

  1. Ослабьте fixing collars also disconnect the top hose of a radiator from a cover established on a head of cylinders of the thermostat.
  2. Turn out fixing bolts and uncover the thermostat the case.

Bolts of fastening of a cover of the thermostat

  1. Take the valve of the thermostat from the case and remove a sealing ring.

Check

 PERFORMANCE ORDER

  1. Before definitively to affirm as opinion on a thermostat exit out of operation, check up level of a cooling liquid in system, a condition and effort of a tension приводного a belt (see the Head of Adjustment and car routine maintenance), and also serviceability of functioning of a measuring instrument of temperature.
  2. One of the possible reasons of too slow warming up of the engine (according to measuring instrument indications) is thermostat jamming in open position. Replace the thermostat new.
  3. In case of an engine overheat touch a hand the top hose of a radiator. If the hose not нагрет, probably, the thermostat is jammed in the closed position, blocking circulation of a cooling liquid through a radiator. Replace the thermostat.

At all do not maintain the car with the removed thermostat! Thus the feedback of the onboard processor that will lead to increase of toxicity of the fulfilled gases and excessive increase in the expense of fuel can be broken off.

  1. If the top hose нагрет, it means that the cooling liquid regularly circulates through a radiator, i.e. the thermostat is opened. Address to materials Diagnostics of malfunctions Has undressed.
  2. The most exact results are given by thermostat check on a workbench.
  3. Remove the thermostat from the engine (Engines see the Head).
  4. Tie up to assemblage of the thermostat a piece of a wire and lower it in the capacity filled with water There lower the thermometer.

Check of serviceability of functioning of the thermostat

Track, that the thermometer and the thermostat did not adjoin to walls and a capacity bottom!

  1. Start to warm up slowly water, watching change of indications of the thermometer, - operation of the valve of the thermostat should occur in exact conformity to requirements of Specifications in the Head of System of cooling of the engine, salon and air conditioning heating.
  2. Estimate size of full opening of the valve, - the rating value makes b - and = 8 mm.

Check of completeness of opening of the valve of the thermostat

Installation

 PERFORMANCE ORDER

  1. Installation is carried out in return sequence. Pay attention to following moments the following.
    1. Carefully smooth out interfaced surfaces and replace sealing elements;
    2. Place the thermostat in a casing, it is correct it сориентировав;
    3. With demanded effort tighten bolts of fastening of a cover;
    4. Restore initial connection of all hoses and electroconducting (where it is required, establish into place removed gauges);
    5. Fill in in system cooling liquid (address to the Head of Adjustment and car routine maintenance);
    6. Start the engine, warm up to working temperature and be convinced of absence of leaks.
On petrol engines OHC the thermostat should come into grooves
On diesel engines the thermostat should be turned an aperture upwards
