GENERAL INFORMATION

Engine 1FZ-FE thermostat

1. Thermostat
2. Laying
3. Inlet branch pipe

Prevention

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


Check

PERFORMANCE ORDER
1. Before drawing a conclusion on malfunction of the thermostat check 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 determine by slow increase of temperature according to the index, or on slow heating of air by a heater), a probable cause is the zalipaniye of the valve of the thermostat. In this case the thermostat replace.
3. At an overheat of the engine check heating of the top hose of a radiator. If the hose warm, and the engine hot, the thermostat is closed, blocking liquid access from the engine to a radiator. Replace the thermostat.

Prevention

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


Replacement

PERFORMANCE ORDER
1. Disconnect the battery from weight and merge liquid.
2. Disconnect from the thermostat vacuum hoses (if are provided).
3. Remove the thermostat case, the hose can be not disconnected from the case.
4. Get the thermostat, having paid attention to its orientation (the spring of the thermostat is turned to the engine).
5. Carefully remove old consolidation.
6. Replace laying (since 1993 laying 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 liquid, start the engine and be convinced of lack of a leak.
