1998 Volkswagen Jetta Question: Coolant leak
A coolant leak will not unfortunately get better. I would have the cooling system pressurized to determine the source of the leak. A repair shop will use something that resembles a bicycle to put pressure in the cooling system that simulates the engine running conditions and so it should be simple to verify exactly where the cooling system is leaking from. It is better to deal with the problem now than have the engine overheat in the middle of no where and have to be towed to a repair facility that you may have to choice at random.It is not worth potentially damaging your engine. . - patrick mannion
