Inspecting For Inlet Restrictions
WARNING: This page is about a different variant/trim than selected.
Inadequate heater performance may be caused by a metal casting restriction in the heater hose inlet.
DO NOT WASTE reusable coolant. If solution is clean, drain the coolant into a clean container for reuse.
WARNING:
Do not loosen the radiator draincock with the system hot and under pressure. Serious burns from the coolant can occur.
- Drain sufficient coolant from the radiator to decrease the level below the heater hose inlet.
- Remove the heater hose.
- Inspect the inlet for metal casting flash or other restrictions.
