FAQ:
Q: How does the coolant flow work in a Prius?
A: The second generation Prius, model years 2004-2009, uses a 3-way valve to control coolant flow between the engine, the hot coolant storage tank (thermos), and the heater core. Thus it’s involved in heating the passenger cabin (when requested), as well as reducing cold start emissions (with the coolant storage system).
Q: What kind of antifreeze does a Toyota Prius use?
A: This antifreeze uses organic acids but not 2-EHA and usually include silicates to provide protection for aluminum surfaces, very important for cars such as Prius. The differences are minor but play a big role in how the engine is protected.
Q: How often should I cool my Toyota Prius?
A: This causes leaks and can lead to very costly repairs. This is another reason to do your homework on all your fluids for your vehicle. Due to the nature of this coolant, most manufacturers (including Toyota) recommended a 30,000 mile service interval, which about 90% of consumers more than likely avoided.
Q: What kind of system does a Toyota Prius have?
A: Hybrid vehicles such as the Toyota Prius have two systems that integrate and work with each other. They are a standard gasoline engine and a high voltage system. The High Voltage or HV system requires complete isolation from the other systems. This means that everything about it is special and must be treated as such.
