Air Conditionner Maintenance - 140 Chassie
 

OK - so things are good today, but the 1992 500SEL is a few years old and configured with air conditioning components behind the dashboard.

Are there maintenance task I can perform or an air conditioner professional (one with proper tools) can perform to lengthen the life of the air conditioner.

I am most concerned with the components behind the dash - which may be the Evaporator.

Thanks

Totally unlike any other subsystem of your car, the a/c system is not something on which you perform preventive maintenance. If it still works, and is fully charged, DON'T MESS WITH IT.

About the only thing that could be called PM would be keeping the condensor and evaporator fins clear and not bent.

What happens when you connect gauges to an a/c system is that you stand the chance of introducing moisture. Moisture is the enemy of your a/c system internals. Any moisture combines with the refrigerant to produce an acid that will eat everything up from the inside out.

Don't mess with it,
