Notes regarding installation:
-
Tightening torques of bolts -A-: 10 Nm (7 ft lb)
-
Connect coolant hoses to the heater core correctly (bottom hose coolant supply, top hose coolant return).
-
The coolant pump -V50- of the pump valve unit must not be operated until the cooling system has been bled (dry running will damage the pump).
For this reason, do not connect the 2-pin connector to pump valve unit until after bleeding the cooling system.
-
Connect coolant hoses to the engine correctly (pay attention to markings made).
-
Bleed cooling system.
-
Check that grommet between engine compartment and plenum is correctly located after installing.
