The heating radiator on a VAZ 21099 car is removed in the event of coolant leaks in the cabin or for preventive cleaning of the honeycomb and flushing with technical compounds. To remove the heating radiator, it is not necessary to go to a car workshop, since all the work can be done independently without using a professional lift.
It is necessary
- - wrenches М10 and М8;
- - a container for collecting coolant (at least 5 liters);
- - flat screwdriver;
- - crosshead screwdriver.
Instructions
Step 1
Carefully disconnect the negative cable from the battery terminal, then remove the crankcase guard. When doing so, make sure that the expansion vessel lid and the heating tap itself are fully open.
Step 2
Drain the coolant from the system. To do this, unscrew the hole plug. It is just designed to drain the remaining liquid from the fuel system of the VAZ 21099. Do not forget to substitute a container under the radiator drain hole, and be sure to take into account that its volume can accommodate at least five liters of liquid.
Step 3
After the coolant is completely drained, disconnect the connector of the wires connecting the electric fan. Do the same with the two fan sensor wires.
Step 4
Loosen the clamps that tighten the outlet, inlet and steam outlet hoses. Then carefully disconnect all three hoses to allow you to remove the radiator mounting brackets. To do this, unscrew the two nuts, which you can find at the top of the electric fan casing.
Step 5
Now you can start removing the heating radiator itself, located in the engine compartment. In this case, keep in mind that it can only be removed together with the fan housing, which, in turn, is fastened with three bolts and one nut. They need to be unscrewed in order to disconnect the fan casing from the radiator on the VAZ 21099.
Step 6
On the lowest mount there are two pillows. Examine them carefully and assess the condition. If the pillows have lost their elasticity, are torn or become dilapidated, be sure to replace them.
Step 7
After the heating radiator for the VAZ 21099 is in your hands, you can start repairing or cleaning it, depending on what it was filmed for.
