Water Pumps, Thermostats, Radiators, Hoses, Fan Clutches, Belts. After 20 years as a radiator shop in Huntington Beach, Westminster and the Fountsin Valley area, and working on radiators as big as Volkswagon Bugs (they have radiators now), we have more experience in radiator and cooling system repair than 99% of the auto shops in Huntington Beach.
A failure can be as small as a loose hose clamp, as big as a cracked head or block. Either one can bring the car to a stop. Preventative maintenance is your best bet and a little vigilances by looking at your temperature gauge on a regular basis. Remember, besides tires and gas, the single biggest reason for on road failure is the cooling system!
