It could be a small enough leak that it evaporates before dripping.
Same color as what?
Find where it is running out and repair the cause.
There's a leak somewhere in your coolant system. Check the radiator and the hoses.
There might be a leak in the water pump, or in the radiator. Maybe even check the radiator hoses for cracks and leaks.
no
probably bad headbolts that have stretched. have a radiator shop pressure test the system to see if coolant is escaping into cylinders.
Water pump out, ruptured tank on radiator, or head gasket blown probably in that order.
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out
Hoses? Intake manifold? Heater? Thermostat housing? Freeze plugs? Radiator? Pressure test system to help find
Yes. If a water pump is leaking, it leaks anti freeze. Anti freeze, (coolant) can also leak from the radiator, or from water hoses.
a hole in the radiator
