Pic. 177. Heater: 1 - air intake cover; 2 - air intake cover gasket; 3 - radiator gasket; 4 - radiator casing; 5 - fan guide casing; 6 - fan casing; 7 - bracket for fastening the fan casing; 8 - air distribution cover; 9 - clamping bracket for fastening the fan casing; 10 - additional resistor; 11 — a protective casing of a heater; 12 - radiator; 13 - supply pipe; 14 - edge; 15 - aluminum radiator (variant execution); 16 - outlet pipe; 17 - fan impeller; 18 - electric motor; 19 — a pillow of the electric motor; 20 - spring bracket for mounting the electric motor.
The plastic casing 4 of the radiator is fastened with four studs to the bulkhead shield amplifier under the air intake box, which can be accessed under the instrument panel. The radiator casing with the air intake box are sealed with a sealing rubber gasket. A radiator 12 is installed in the radiator casing and sealed with a rubber gasket 3. The radiator consists of two rows of tubes, cooling plates and two tanks. The right radiator tank is divided by a partition into two cavities. A drain pipe and a faucet 14 with an inlet pipe 13 are attached to the tank. The ends of the pipes go into the engine compartment through the bulkhead and are connected by hoses to the cooling system. The outlet of the pipes to the engine compartment is sealed with a rubber seal.
The air that has passed through the heater radiator enters through the guide casing 5 into the fan casing 6. An electric fan is attached to the center of the plastic guide casing with spring clips 20. On the left wall of the casing 6 of the fan on the inside there is an additional resistor 10 (resistor). Connecting it or disconnecting it from the power supply circuit of the electric fan with a three-position switch provides a low or high speed of the impeller 17 of the fan.
The heater is controlled by an electric fan switch, rotary deflectors and two handles 13 (pic. 178) faucet control and air intake cover. The lower valve control handle is connected by a flexible rod 6 to the valve lever and regulates the amount of coolant entering the heater radiator. The upper handle is connected by a flexible rod / to the lever of the air inlet cover, which regulates the flow of air into the heater. To make it easier to remember the position of the control handles, on the left side of the instrument panel there are symbols in the form of triangles, the vertices of which indicate that the air intake cover and valve are closed.
Pic. 178. Heater control drive: 1 - flexible rod for controlling the air intake cover; 2, 5 and 7 - clamping brackets; 3 and 8 - shells of flexible rods; 4 - bracket for fastening the shell of thrust; 6 - flexible rod control crane; 9 - spring nut for fastening the bracket of control levers; 10 - fastening screw; 11 - bracket for control levers; 12 — heater control levers; 13 — handles of control levers.
Many parts and components of the heater are interchangeable with car parts VAZ-2101, VAZ-2105 and VAZ-2106. Interchangeable with VAZ-2101 parts are the radiator shroud with an air inlet cover, the fan shroud with an air distribution cover, a valve with inlet and outlet pipes, an electric fan assembly with fastening parts, control levers with an assembly bracket. With VAZ-2105 parts, the heater radiator assembly with pipes, a resistor are interchangeable; with VAZ-2106 parts, deflectors assembled with pipes are interchangeable.
It is forbidden to turn on the electric fan with the air intake cover closed and the heater tap open.
