The cooling system is largely an out –of –sight, out –of –mind scenario with most drivers ignoring it until the temperature gauge goes all the way up, or warning light comes on which is usually too late and results in overheating. If your heater is not putting out hot air but temperature gauge reads normal could indicate low coolant level , insufficient to supply heater core . Puddles or adding coolant frequently indicate leaks, and system should be checked as soon as possible. Feel free to give us a call to schedule an inspection. Just as oil and tire pressures should be checked regularly so also should your cooling system. Maintaining fresh coolant can go a long way in reducing corrosion/ contaminates in the cooling system and extend the life of radiator, heater cores, thermostats and water pumps.
