The fans are for the aircon and only come if needed at the last moment to assist the cooling of the engine. Normally when it's too late.....Thanks I will give that a go. Do the two small fans in front of the rad have anything to do with cooling the engine or are they just for the heating system. Is there a way of testing them? I’ve never seen them on
