Classic Chevy Cooling System and Belts

Classic Chevy engines can generate a lot of heat. Their cooling systems are what help prevent overheats.

How one works is a process that starts with liquid coolant (antifreeze), which travels between radiator hoses -- inlet and outlet hoses, to be exact. Many different parts make that movement possible -- everything from a water pump, serpentine and/or V-belts, and a belt tensioner to one or more idler pulleys. Even the power steering pump, air conditioning compressor, and alternator factor in. As the fluid travels, a radiator cap pressurizes it, and it traps that excess heat.

When absorption is at its max, a set of fins releases the heat, and a cooling fan helps scatter it. As a result, the engine runs a little cooler: it can keep working as well as vintage can, and a motor that runs right lasts longer.

Unfortunately, though, no cooling system lasts indefinitely. If one goes bad, it'll cause other problems, like heating and AC malfunctions if not outright engine failure. Fortunately, if you're seeing the signs of, say, a bad radiator -- odd engine noises, fin damage, antifreeze turned to sludge, the sweet, syrup-like smell of ethylene glycol -- our auto parts store has what your repair or restoration project needs.

Get Cooling System Repairs Done Right -- Choose Classic Chevy Parts

Whether you need a fan shroud for a Chevrolet Impala from the mid-1960s, a mounting panel for a 1970s Chevy Camaro, or something in between, you'll find it here. Ditto for installation accessories -- everything from fittings and bolts to seals and clamps. You can order it all online, too, in a few easy clicks. Buy now -- we ship and deliver fast, right to your address.
