HEATING AND COOLING SYSTEM

Heating AND Cooling System

What is the cooling system?

This system keeps the engine temperature remains constant. And also, the hot coolant heats the air to adjust the passenger moved at room temperature.

If coolant is leaking out

This causes the engine swordfish just became too hot (overheating), but also damage the machine itself.

Inspection interval

Inspection:

Every 40.000 km (24.000 miles) or 2 years

Radiator cap
  What is the radiator cap?

• Allow the coolant to remain at a constant pressure to keep the coolant boiling point is above 100 º C. Radiator cap also improves cooling performance by making the temperature difference between coolant and the air is greater.

• The valve pressure (pressure valve) opens at high temperatures to transmit coolant to the reservoir tank. On the other hand, the vacuum valve opens at a pressure which declined to draw coolant from the tank back into the reservoir.

The importance of checking the radiator cap

If he is not working properly, then it causes overheating.

Inspection interval

Inspection:

Every 40.000 km (24.000 miles) 2 years

Engine Coolant

 What is liquid cooling?

Have the following roles.

• Prevent the cooling fluid does not freeze.

• IMencegah to part-part cooling system does not rust.

• Prevent overheating. (Higher boiling point than water.)

If the coolant is not changed

Rust will inhibit its function, and radiators, pipes, tubes, etc.. become damaged.

Replacement intervals

• Replace engine coolant according to the distance that has been taken or the period of time because it is difficult to assess the level of ugliness with only looking at it.

  Replacement (the Corolla for general states):

     every 40.000 km (24.000 miles) or 2 years

• See schedule for different treatment depending on the model.

These types of coolant

There are two types of LLC (Long Life Coolant): red and green. Both of them have ingredients that are similar.

Thickness

Use coolant mixed with water, but it will freeze easily when not used with the proper density. Use LLC density appropriate for each region. See the Owners Manual for the proper density LLC.
