A thermostat is a valve that regulates the amount of coolant flowing through the cooling system radiator to maintain a normal engine temperature. The typical sign of a faulty thermostat is rapid overheating of the car engine. To fix this problem, remove the thermostat from the system, and install a compatible replacement thermostat. The accumulation of air in the cooling system reduces the efficiency of the cooling system by hindering the coolant flow through the system. Troubleshooting this problem involves eliminating the air from the system by bleeding.

A leakage in the radiator hoses may result from wear and tear. Fixing this problem involves replacing the faulty hoses with new ones. Replacing the hoses at a certain time interval regardless of whether there is a leakage or not helps to prevent this problem. Another option is to patch the hose, although this repair is usually temporary.
