Why Coolant & Radiator Hose replacement is so important.

Car or truck motors need to keep cool if they are to maintain operational status. That's why your Audi 100 Series engine has a system of cooling hoses transferring water and ethylene glycol throughout the engine. The radiator hoses under your hood connect the radiator to the water pump and to the engine block, while other coolant hoses direct coolant through the coolant expansion tank, heater core, and thermostat housing. If a Audi 100 Series radiator or coolant hose develops a leak, then the motor will not be able to cool itself and the temperature will increase; leading to engine failure.
