Is Coolant on ground bad and expensive? Should I take it to a repair shop ?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. I would definitely recommend not driving the vehicle until this is resolved. If you have a coolant leak, remember that your cooling system is under pressure and that the leak could become significant rapidly. This could result in engine overheating and possible damage, as well as a mechanical breakdown. A pressure test of the cooling system would be helpful to determine the source of the leak. It is concerning that the heater blow cold, but this could be due to low coolant level in general.
