Have recently purchased a 1999 primera Station wagon with the SR20DE
2litre engine. First I wish to change the coolant but cannot find the Engine Coolant drain plug. Second The Owners manual mentions that the Air conditioner air inside the passenger compartment is cleaned by a pollen filter built into the Air conditioner. This filter is supposed to be replaced every 12 months but the manual does not tell you how to access this filter to replace it. Would appreciate any help with the above. Thanks.
