Car engine that uses a cooling system using water as the temperature control thermostat. Serves as a thermostat valve / faucet water flow from the engine to the radiator. While still cold, the thermostat closes so the water will spin the engine block that make ideal working temperature is reached quickly.
When the working temperature is reached, the thermostat opens so that water began to flow into the radiator to cool the temperature of the engine not exceeding its temperature, when the temperature is getting too cold thermostat closes again, so on that make the engine temperature becomes stable.
Thermostat as a 'scapegoat'
Often heard the case of overheating caused by the cooling system, or the case of machines that are always in hot conditions.
Of the cases not a few workshops to recommend to revoke the thermostat because it is considered as the culprit. There are also workshops suggested that replacing the thermostat temperature lower than the standard work on the grounds Indonesia climate is quite hot (tropical).
Repeal the thermostat is wrong, because the machine will reach the temperature of his work long enough, do not even reach the ideal working temperature. The temperature of the machine becomes unstable, while it is down a hill or high speed engine temperature will be very cold.
Replacing the thermostat working temperature is lower than the recommended factory also makes the engine work under ideal working temperature.
Solution: Observe the Working Temperature Machine
If we use a used car or old, try to look at our car engine working temperature. See the guide needle temperature on the instrument panel.
Try also a time to ask to formal workshop or participate in mailing lists or similar car club to ask at what point our engine temperature under normal conditions.
If the needle temperature showed a lower temperature for example, only a quarter (normally half), then there are the following possibilities:
1. Thermostat has been revoked: Making the engine work in cold conditions, usually because it never occurred to the engine overheating, so the thermostat removed.
Solution: Install the thermostat according to the size of the factory recommended temperatures.
2. Thermostat stuck: Occurs when the thermostat is damaged so it is always in the open condition.
Solution: Replace the thermostat according to the size of the factory recommended temperatures.
3. Low-temperature thermostat work: As a result of using low work-temperature thermostat makes the engine work at a temperature of low employment.
Solution: Replace the thermostat according to the size of the factory recommended temperatures.
