OEM Mazda Radiator Cooling Parts

Refine Results

What do car radiators do? They use antifreeze to collect excess engine heat, and then they help dissipate it. This helps prevent engine overheats.

How does a car radiator work? The process begins with the antifreeze. It flows through inlet and outlet hoses, a radiator cap pressurizes it, and it absorbs as much heat as it can as it travels. Flat, fin-style aluminum tubes expel the heat, and a fan scatters it into the air nearby.

Some radiators do the job with extra fins, called turbulators. They dissipate heat better. Others do the job for transmissions, too, using side-mounted tanks called transmission coolers. Instead of releasing excess transmission heat into the air, they transfer it to the antifreeze.

Unfortunately, radiators can eventually develop problems. Luckily, if you think yours is failing or has already gone bad, there are signs that'll tell you. They include:

  • Strange engine noises
  • A syrupy ethylene glycol odor
  • Dirty or gooey antifreeze
  • Antifreeze leaks
  • Car HVAC malfunctions
  • Unusually high readings on your temperature gauge

The ethylene glycol smell usually means you've got leaking coolant. To figure out what exactly is happening, do an inspection.
