The AAV for a D-jet 1800/140/164 is bolted to the side of the cylinder head and it has a bulb that is exposed to coolant and works it like a coolant thermostat, but in reverse as it closes when it get hot. The 164 AAV is different, but works the same.

Starting with the K-jet/CIS 140, Volvo/Bosch used an AAV with an electric heating element.
