نشتی رادیاتور بخاری

The heater matrix inside the dashboard leaking coolant into the cabin. It is a small radiator in the ducting, so its leak arrives in the passenger compartment rather than under the vehicle.

The signs are distinctive and reach the driver first: a sweet smell, a greasy film on the inside of the windscreen that will not clear, and damp carpet in the passenger footwell. Coolant loss with no external leak and a misted screen is this before it is a head gasket. It also blocks, which is the other failure: heating that works on one side or not at all with a hot feed hose, from sediment in a system topped up with water. The labour is the cost — most are behind the dashboard — so confirm properly before committing.
