4.3. The thermostat

The engine thermostat 1FZ-FE

1. The thermostat
2. A lining
3. An inlet branch pipe

The prevention

Works are carried out on the cold engine with observance of security measures (antifreeze is poisonous).


1. Before drawing a conclusion on malfunction of the thermostat check up liquid level, a condition of a belt of the pump and serviceability of the index of temperature (or a control lamp).
2. If the engine is long warmed up (it it is possible to define on slow increase of temperature under the index, or on slow heating of air by a heater) a plausible reason is залипание the thermostat valve. In this case the thermostat replace.
3. At an engine overheat check up heating of the top hose of a radiator. If a hose warm, and the engine hot the thermostat is closed, blocking access of a liquid from the engine to a radiator. Replace the thermostat.

The prevention

On cars with инжекторным the engine driving without the thermostat is forbidden. In the absence of the thermostat the chain of a feedback of automatic control is disconnected by systems of decrease in toxicity and fuel system, profitability of the engine as a result falls.


1. Disconnect the battery from weight and merge a liquid.
2. Disconnect from the thermostat vacuum hoses (if are provided).
3. Remove the thermostat case, the hose can to be disconnected from the case.
4. Get the thermostat, having paid attention to its orientation (the thermostat spring is turned to the engine).
5. Cautiously remove old consolidation.
6. Replace a lining (since 1993 the lining keeps within on edge of the thermostat and represents a sealing ring with a flute), сориентируйте and establish the thermostat.
7. Tighten bolts.
8. Fill in a liquid, start the engine and be convinced of absence of a leak.
