Check of serviceability of functioning and thermostat replacement

Do not open a cover of a radiator and do not remove the thermostat before complete cooling of the engine! See also prevention at the beginning Antifreeze - general information.

Check

 PERFORMANCE ORDER

1. Before finally affirming as a thermostat exit out of operation, check level of cooling liquid in system, a condition and effort of a tension of a driving belt (see. Head Routine maintenance), and also serviceability of functioning of a measuring instrument of temperature.
2. One of possible the reason of too slow warming up of the engine (according to indications of a measuring instrument thermostat jamming in open situation is. Replace the thermostat new.
3. In case of an overheat of the engine touch a hand the top hose of a radiator. If the hose is not heated up, possibly, the thermostat is jammed in a closed position, blocking circulation of cooling liquid through a radiator. Replace the thermostat.

At all do not maintain the car with the removed thermostat! Feedback of the onboard processor that will lead to increase of toxicity of the fulfilled gases and increase in fuel consumption thus can become torn.


4. If the top hose is heated up, it means that cooling liquid circulates through a radiator, i.e. the thermostat is open. Address to materials Diagnostics of malfunctions of knots and car systems.

Replacement

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!


2. Merge cooling liquid from a radiator (see. Head Routine maintenance). If replacement of a mix was made recently, keep it for further use.
3. Walk on the top radiatorny hose to the engine and find a cover of a casing of the thermostat.
4. Weaken a collar and remove a hose from the connecting branch pipe. If the hose "became attached", grasp it nippers (as it is possible closer to the end) and try повращать on a branch pipe for the purpose of destruction of a holding layer. the old hose subject to replacement can be cut simply (try not to scratch a branch pipe).
5. If the surface of a branch pipe contacting to a hose is struck with corrosion, or mechanically damaged, it is meaningful to replace a cover of a casing of the thermostat.

6a. Disunite the electric socket of the sensor of temperature of cooling liquid of the engine (eats), turn out fixing bolts and uncover a casing of the thermostat (Honda Civic). If the cover "became attached", обстучите its hammer with soft the brisk. Prepare for collecting spilled liquid.

6b. Arrangement of bolts of fastening (Acura Integra).

7. Try to remember adjusting position of the thermostat (a finger up), then take it from a casing.

8. Replace rubber sealing laying of the thermostat (see an accompanying illustration).

9. Establish the thermostat in a casing (do not apply any hermetic). Track, that it appeared is developed by a finger up, and the equipped spring the party to the engine (see an accompanying illustration).

10. Establish into place a cover and fix it bolts, having tightened the last with demanded effort.
11. Connect to a cover branch pipe a hose and strongly fix it a collar. Return into place all components acting in film for the purpose of ensuring access.
12. Fill in in system necessary amount of cooling liquid (see. Head Routine maintenance).
13. Start the engine and check it on existence of leaks and serviceability of functioning of the thermostat (see paragraphs with 2 on 4).
