camlex Posted June 8, 2009 Share Posted June 8, 2009 A/C is closed system. No maintenance. Newer coolant goes up to 90,000. When you do your TB, WP etc. Quote Link to comment Share on other sites More sharing options...
George_Jetson Posted June 8, 2009 Share Posted June 8, 2009 You could change the coolant a little early, I personelly think the maint schedules are more of a marketing speal, and not totally realistic. You will not hurt the car by doing it sooner than they recommend.The ac is a closed loop system, but you do have a cabin filter that should be changed, and the condenser fins should be checked for obstructions. Generally you can just backwash them to clean stuff off. BE CAREFULL AROUND THE CONDESSOR treat it gently while cleaning. Quote Link to comment Share on other sites More sharing options...

George_Jetson Posted June 8, 2009 Share Posted June 8, 2009 Hello George,How to make condenser fins straight. Mine is 12 yrs older. That is will helps. They have a tool, that looks like a comb, has several different sides to it. Each side is for different fin "Densities" that will straighten the fins and also dig out any hard core Kamikaze bugs.

George_Jetson Posted June 9, 2009 Share Posted June 9, 2009 Glad to be of help. I have no clue on what the cost would be, my guess that it would not be too bad, (but probably a dealer only item). Quote Link to comment Share on other sites More sharing options...
