What Coolant Does a Honda Pilot Take?

The Honda Pilot uses Genuine Honda Long-Life Antifreeze/Coolant Type 2 (blue), a 50/50 premixed ethylene glycol coolant that is silicate-free, borate-free, nitrite-free, and amine-free. If OEM Honda coolant is unavailable, use an equivalent “Asian Vehicle” phosphate HOAT formula that explicitly states compatibility with Honda systems. Avoid mixing different coolant chemistries.

The Official Recommendation

Honda specifies its own blue premixed coolant—often labeled as Genuine Honda Long-Life Antifreeze/Coolant Type 2—for the Pilot across model years. This coolant is engineered to protect aluminum components in Honda engines and radiators, provide freeze/boil-over protection, and resist corrosion without the abrasiveness of silicates. Because it is premixed at 50/50 with deionized water, it is ready to pour with no additional dilution needed.

Model-Year Compatibility

All North American Honda Pilots (first generation 2003 through current models) are compatible with Honda Type 2 coolant. Some early manuals may reference Honda green concentrate from older formulations; Honda supersedes those with the current Type 2 blue premix. If your vehicle currently contains a non-Honda or different-color coolant, a full drain-and-fill (not just a top-off) is recommended before switching to Honda Type 2.

When OEM Coolant Isn’t Available

If you cannot source Genuine Honda Type 2, you can safely use an aftermarket coolant that matches Honda’s chemistry. The key is matching the formulation, not the color alone.

  • Base: Ethylene glycol
  • Inhibitors: Phosphate-based (Asian vehicle formula), silicate-free, borate-free, nitrite-free, amine-free
  • Mix: 50/50 premix preferred; if buying concentrate, dilute with distilled water to 50/50
  • Labeling: Must explicitly state “Compatible with Honda/Acura” or “Asian Vehicle (Blue/Pink) Phosphated HOAT”
  • Avoid: “Universal,” high-silicate green coolants; Dex-Cool (orange) and other non-Asian chemistries

Matching these specifications preserves corrosion protection, water-pump seal life, and heater core performance. If in doubt, do not mix; instead, perform a complete drain-and-fill with a known-compatible coolant.

Maintenance Intervals and Practical Notes

Most recent Honda maintenance schedules call for coolant service at 10 years/120,000 miles for the first change, then every 5 years/60,000 miles thereafter (often shown as Maintenance Minder code “5”). Always follow your owner’s manual or Maintenance Minder for your specific year. System capacity varies by model year and drivetrain; use the service manual specs and fill only to the MAX line in the reservoir on a cold engine.

Top-Off and Mixing Guidance

Proper top-off technique helps maintain correct concentration and avoid introducing air into the system.

  1. Only open the radiator cap/reservoir when the engine is completely cold.
  2. Top off with the same Honda Type 2 (blue) premix already in the system; match brand/chemistry when possible.
  3. If you have concentrate, dilute with distilled water to 50/50 before adding.
  4. In an emergency, you may add a small amount of distilled water to reach the reservoir’s MAX line; restore the correct 50/50 mix at the next opportunity.
  5. After any significant coolant service, run the engine with the heater on HOT until the cooling fans cycle, then recheck the level to account for purged air.

Consistent chemistry and careful filling minimize the risk of corrosion, scale, and hot spots caused by air pockets.

How to Tell If the Wrong Coolant Was Used

Using an incompatible coolant can cause performance or durability issues. Watch for these warning signs after a recent service or top-off.

  • Discoloration, sludge, or gel-like deposits in the reservoir
  • Sweet smell with rapid level loss (possible leaks from seal incompatibility)
  • Overheating, erratic temperature gauge behavior, or poor cabin heat
  • Water-pump noise or premature bearing/seal wear

If any of these occur, a complete flush and refill with Honda Type 2 (or a verified compatible Asian phosphate HOAT) is advisable, followed by system bleeding and leak checks.

Summary

The Honda Pilot is designed for Genuine Honda Long-Life Antifreeze/Coolant Type 2 (blue), a 50/50 premixed, phosphate-based ethylene glycol coolant that is silicate-, borate-, nitrite-, and amine-free. Use the OEM fluid or a clearly labeled Asian-vehicle compatible equivalent, avoid mixing chemistries, and follow Honda’s maintenance schedule (typically first at 10 years/120,000 miles, then every 5 years/60,000 miles). This ensures optimal corrosion protection, cooling performance, and component longevity.

What kind of coolant does a Honda Pilot 2025 take?

Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
This coolant is premixed with 50% antifreeze and 50% water.

What color is pilot coolant?

What color coolant does Honda Pilot use? It’s decisive to understand that color doesn’t matter. While most Organic Acid Technology (OAT) coolants are usually orange, yellow, red or purple, Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow.

Does Honda use a special coolant?

Always use Honda All Season Antifreeze/Coolant Type 2. This coolant is pre-mixed with 50 percent antifreeze and 50 percent water. Never add straight antifreeze or plain water. If Honda antifreeze/coolant is not available, you may use another major-brand non-silicate coolant as a temporary replacement.

What kind of coolant does a 2018 Honda Pilot take?

Life Antifreeze Coolant Type 2
Whether you drive a pre-owned Honda Accord or brand-new Pilot, each release year and model has a brand-recommended coolant, with the most common one known as the Long Life Antifreeze Coolant Type 2.
