But the air-con on, should come on then.

it will come on when the engine gets hot enough

usually takes ages on 172/182's as people rarely change thermostats

Will come on slow speed with the AC otherwise when the coolant hits 98c iirc. Which will take a while, leave it idling for long enough it will come on eventually but it'll take 30 mins+.

Mine comes on for like 2mins every 20mins or so, if it's just on idle
