Although the A/C system should not be serviced by the do-it-yourselfer, preventive
maintenance should be practiced to help maintain the efficiency of the vehicle's
A/C system. Be sure to perform the following:
- The easiest and most important preventive maintenance for your A/C system
is to be sure that it is used on a regular basis. Running the system for five
minutes each month (no matter what the season) will help ensure that the seals
and all internal components remain lubricated.
NOTE: Some vehicles automatically operate the A/C system compressor
whenever the windshield defroster is activated. Therefore, the A/C system would
not need to be operated each month if the defroster was used.
In order to prevent heater core freeze-up during A/C operation, it is necessary
to maintain proper antifreeze protection. Be sure to properly maintain the engine
cooling system.
Any obstruction of or damage to the condenser configuration will restrict
air flow which is essential to its efficient operation. Keep this unit clean
and in proper physical shape.
NOTE: Bug screens which are mounted in front of the condenser
(unless they are original equipment) are regarded as obstructions.
The condensation drain tube expels any water which accumulates on the bottom
of the evaporator housing into the engine compartment. If this tube is obstructed,
the air conditioning performance can be restricted and condensation buildup
can spill over onto the vehicle's floor.
