182 cooling system



Hiya all

Quick question

When doing a coolant change on a 182. Is there any bleed nipples to undo or not??
Or do it normal way with cap off and highish revs to bleed??

Anybody know???

Theres a bleed bolt on the thermostat housing that must be removed when your filling it. As you can't fill the rad up with the thermostat closed you'll need to fill it cold then run the engine with the expansion tank cap off and get ready to add more coolant quickly when the thermostat opens as it'll drop pretty fast. Need to keep your eye on the extra filling needed or it'll just draw a load of air in.
