It's probably the heater control valve that's leaking as the cores are fully sealed up (though I'm sure they do break down over time too). THere are a few places they can leak from, but the most common ones are the join between the two halves of the valve body and from the top where the sliding 'pinion' (which is what the control shaft moves) comes out.SaabArrogance said:It's leaking. Puddles on left hand floor. Where can I get replacements that won't interfere with current driver's pedal?
It depends on how much it is leaking outside the car. If the valve is leaking a small amount of fluid can run along the bottom of the pipes and, if the bulkhead seal is not perfect, can continue along the pipes 'till it reaches the lowest point and drips off.SaabArrogance said:Why would it be leaking outside the car as well? Would the valve do that or could it be a bad water pump as well? I'm dying here, and so is my car.
