About Heater Valves

The Mazda heater valve is a very important part of a vehicle’s heater system. It’s usually located behind the vehicle dashboard. It works independently of the rest of the cooling system and controls the amount of coolant that is flowing through the heater core. The coolant that flows to the heater core travels through the heater hoses. These hoses connect the engine to the heater core. There are however, some vehicles which don’t use a Mazda heater valve. In this case, the coolant will flow freely from the engine to the heater core via the heater hoses.

The Mazda heater valve can be a manual valve, a vacuum valve or electrical.

The Mazda heater valve can have problems with not opening and closing as it should. This could be caused by it sticking. In this case, some WD40 or other lubricant may help. If it doesn’t however it may need to be replaced. If your heating system isn’t working and is bled properly, it may be an issue with the Mazda heater valve. Alternatively, if the vehicle’s heating is always on it may be an issue with the Mazda heater valve being seized open.

Mazda trivia

  • The attempt by Mazda to make a fast electric car was very successful. The Mazda RX-7 was built in 1979 and could reach an impressive 111.8mph.
  • The first vehicle that Mazda ever produced was a three-wheeled truck called the Mazda-go. Only 66 were built in total for its release in 1931.
  • Mazda has always been big fans of the rotary engine, and although they originally started using them to help distinguish themselves from other car manufacturers, they are still the only car manufacturer to mass-produce rotary engine-powered vehicles.
  • Mazda is the only Japanese car manufacturer not to be based in Tokyo. Instead, they work out of Hiroshima and were there when a nuclear bomb was dropped. The Mazda factories actually survived the atomic bomb thanks to a small mountain being in the way.
  • The name Mazda comes from both the name of the founder (Jujiro Matsuda) and the Zoroastrian God of Wisdom, Ahura Mazda.
