Engine cooling and lubrication system Chevrolet Orlando 1

Cooling system pressure
The engine cooling system is sealed. When the engine is running, as the coolant heats up, the pressure in the system increases. It is limited by a safety valve...

Lubrication system pressure
To lubricate the surfaces of parts that rub during engine operation, engine oil is supplied under pressure through the lubrication system channels. The gear...

Engine lubrication system pressure
Minimum permissible oil pressure in the lubrication system when the engine is idling, kPa 130 Note: The reason for the decrease in oil level may be increased...

Checking oil pressure
To perform the work you will need a pressure gauge with an adapter to check the oil pressure. It is more convenient to do the work with an assistant. 1. Start...

Coolant temperature sensor
The coolant temperature sensor is designed to monitor the engine temperature. The sensor is a thermistor that changes its electrical conductivity depending on...

Oil filter
To clean the engine oil in the engine lubrication system, an oil filter with a replaceable filter element is used. The filter is located on the front wall of...

Motor oil
Motor oil is used to lubricate and cool the rubbing surfaces of engine parts. Lack of or excess oil can lead to engine damage and, as a result, to costly...

Classification of motor oil
Classification of the American Association of Automotive Engineers (SAE - Society of Automotive Engineers) classifies oils by viscosity and divides them into...

Requirements for oil quality and replacement periods
Engine oil requires periodic replacement. In accordance with the maintenance plan, under normal operating conditions, the engine oil is changed every 15,000...

Cooling liquid
The engine cooling system uses special cooling liquids (antifreezes) consisting of ethylene glycol, water and additives. They have a low freezing point and a...

Cooling system — description and testing
The cooling system is designed to maintain the engine operating temperature within optimal limits. It consists of a cooling system pump, radiator, expansion...

Thermostat — Checking and Replacing
The thermostat is designed to maintain the optimal temperature of the engine and accelerate its warm-up. Depending on the operating mode, more or less heat...
