Russell

Russell went out of his way to assist me with my car when it wouldn't start for me. He called to confirm our appointment and to ask if he could come early. When my car started right away, he still gave me a jump to gauge the battery power level and suggested I bring my car back to the dealer for further servicing since it was still under warranty. Didn't try to pressure me into anything I didn't need. Great service.

All about Radiator Replacement

The radiator performs a critical function; it keeps the engine from overheating. While running, the engine produces heat. Coolant flowing through the system absorbs and removes extra heat from the engine. The coolant then passes through the radiator where it cools off and is later circulated back to the engine to absorb heat again. A radiator has two tanks that are connected to each other through aluminum or brass tubes. When the coolant passes through these tubes, the radiator cooling fan blows air across the radiator to lower the temperature of the coolant. The tank is usually made of plastic, and it is common for it to crack and start leaking coolant. If the tank or the tubes crack, coolant will leak , the vehicle will overheat and could cause severe engine damage. Radiators also tend to clog over time. When this occurs, not enough coolant flows through the radiator leading to heat build-up, causing the engine to overheat.
