Removing the coolant hose from the heater unit
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The hose is too short to be left in place when lowering the engine.
Turn the quick-release connector slightly in the direction of the arrow. At the same time, pull the hose towards you.
Collect the coolant that flows out.
