Consequences of not replacing a bad heater core in 2002 Ford taurus? - 1

Being cold in the wintertime.

Coolant leaking inside the car, possibly leading to engine overheating.

As long as you bypass it, the only consequence is you won't have heat.

Hi simple the labour costs involved in such an enterprise.

Cons = loss of fluid? Staining interior potentially. Smell. Over heating of engine ( due to coolant loss and pressure drop in system) more cost for rectification rather than interceding early. Lack of heating. Lack of heat to windscreen to assist defrosting. Finally if we lose enough coolant we risk engine issues that may be very expensive.

No heat and a wet floor.
