The 2017 Honda HR-V uses Honda Long-Life Coolant Type 2 (blue), an ethylene glycol–based HOAT coolant. Use Honda Genuine Long-Life Coolant Type 2 or an equivalent that meets Honda specifications, and avoid mixing different coolant types.
Understanding Honda’s Long-Life Type 2 coolant
Honda’s Type 2 coolant is an extended-life, silicate-free formulation designed to protect aluminum and other metals in the cooling system. It typically comes blue in color and is intended for long service intervals when used as directed by Honda.
What is Type 2 coolant?
Type 2 coolant is a protected, extended-life coolant that uses Hybrid Organic Additive Technology (HOAT) or Organic Additive Technology (OAT) chemistry and an ethylene glycol base. It is formulated to be compatible with Honda engines and radiators and to resist corrosion without relying on silicates.
For the HR-V, this means selecting a product that explicitly states it meets Honda specification for Type 2 long-life coolant, rather than older Type 1 (green) formulations or universal mixes that may contain incompatible additives.
Compatibility and labeling essentials
To ensure proper protection and avoid damage to your cooling system, focus on labeling and compatibility when shopping for coolant.
Before shopping for coolant, consider these compatibility guidelines
- Use Honda Genuine Long-Life Coolant Type 2 or an equivalent labeled as meeting Honda specification for Type 2 coolant.
- Choose an ethylene glycol–based coolant that is silicate-free and formulated for use with aluminum engine components.
- Avoid traditional green “Type 1” coolant or universal coolants that contain silicates or phosphate additives not compatible with Honda Type 2 requirements.
- Opt for a pre-diluted 50/50 mix or a concentrate that you dilute with distilled water according to the product instructions (60/40 or other ratios are common in some markets, but 50/50 is standard for many Honda applications).
Using the correct coolant formulation helps protect the cooling system from corrosion and overheating, and it supports long-term reliability for the HR-V.
Maintenance and replacement guidelines
Knowing when and how to replace or refresh coolant is important for maintaining engine temperature control and preventing damage.
Before maintenance and replacement, keep these guidelines in mind
- Consult the owner’s manual for the recommended coolant service interval. Type 2 long-life coolant is designed for extended life, but exact intervals can vary by market and model year; Honda typically suggests long intervals such as around 10 years or 120,000 miles under normal conditions, with confirmation in the manual.
- If you are refilling, use a 50/50 mix with distilled water (or as specified on the product label) unless the coolant you purchase is pre-mixed.
- If you are changing from a different coolant type (for example, Type 1 green) to Type 2, have the system flushed to remove old additives that could react with the new coolant.
- After refilling, bleed/vent the cooling system as directed in the service manual to remove air pockets and ensure proper circulation.
Adhering to these steps helps maintain optimal cooling performance and reduces the risk of overheating or component damage.
Summary
For the 2017 HR-V, the recommended coolant is Honda Long-Life Coolant Type 2 (blue), a silicate-free, HOAT/OOAT formulation based on ethylene glycol. Use Honda Genuine Type 2 or an equivalent that meets Honda specifications, avoid mixing coolant types, and follow the owner’s manual for service intervals and proper mixing and bleeding procedures.
