I drive a 1984 300 TD in good running order. i recently noticed on a rare long trip form Pittsburgh to Buffalo that the car is using/losing engine coolant. there is no obvious burning, smoking, or leaks evident. there are typically a few small drops of coolant and/or oil hanging at the bottom of the motor near the oil pan. Although parking the vehicle leaves practically no evidence of leaks. my garage floor shows only very minor very small spots and the bottom of the car is almost completely dry. i recently had all of the coolant hoses replaced in the engine compartment due to a coolant leak near the climate control manifold (correct word? where the heating/cooling lines pierce the engine compartment into the passenger cabin) and all evidence of leaks at this location are resolved. i still get a faint coolant smell under normal vehicle operation but i cannot see any evidence of a significant leak or burning of coolant. has anyone had a similar experience or can anyone advise me on this issue? thanks for your help.
