Disunite this connection before remove the condenser in cars with the 5-cylinder engine; inhaling moment: 16.5 N of m.

Connection of the line of coolant to the evaporator

Before tightening a bolt of this connection, be convinced that lines are not pressed. Inhaling moment: 16.0 N of m.

Throttle, removal and installation

PERFORMANCE ORDER
1) disconnect lines of a cooler from the evaporator
