Then I open up the airbox and use a small screw to permanently fix the air diverter door in the bottom of the airbox assy in the "cold" position (I screw it shut on the hot side). On virtually any older Volvo, this system is almost guaranteed to be broken and it always fails in the hot position. This makes for worse performance, more wear and more heat in the engine, which is not what you need if you are trying to diagnose an overheating issue.
Everyone who hasn't checked this on their car should do it! A very easy and important modification...

Thanks v8volvo!
I`ll check mine tomorrow. Almost sure it has been done already.
