Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Systems of heating, ventilation and conditioning>> Search of malfunctions>> Heater radiator
Leakage of cooling liquid of the engine in salon testifies to malfunction of a radiator of a heater. Probably, leak is caused by a leaky joint of hoses of a radiator, however this reason is improbable. Attentively examine a rug and a site about ventilating openings of a floor, check presence of signs of moisture or cooling liquid. Leak signs, though less convincing, are a sweetish smell of antifreeze in salon, or a constant easy zapotevaniye of a windscreen.
Excessively high internal pressure can be the reason of leakage of a radiator.
Removal and replacement of a radiator of a heater are interfaced to depressurization of central air and dismantling of an airdistributing box under the dashboard.
