Having replaced the evaporator I've vacuum tested the system and all is OK so now I need to fill it with freon (R134).

Is this a job I should leave to a professional? If so should I get the system flushed before filling?

If it's something I can tackle myself do I need any special equipment aside from the vacuum pump and the little connector with a gauge? Can someone give me the key steps or direct me to some instructions? The book says add 40cc of oil if you replace the evaporator.

Thanks again,

Peter

p.s. the car is a '99 E430
