Parts for your 2020 Mitsubishi Eclipse cross-Coolant

2020 Mitsubishi Eclipse Cross Coolant

Based on Mitsubishi’s technical literature— including the Eclipse Cross Owner’s Manual (MY2020, Cooling System), the Mitsubishi Motors Service Manual (Group 14 – Cooling), and the Mitsubishi Genuine Fluids catalogue — the 2020 Mitsubishi Eclipse Cross is fitted with a liquid engine cooling system and uses a long‑life ethylene glycol coolant (specified as Mitsubishi Genuine Super Long Life Coolant Premium). So yes, coolant is relevant and used on this model.

Coolant does a lot more than just stop freezing and boiling. In the 2020 Eclipse Cross, it carries heat away from the 1.5‑litre turbocharged engine and helps stabilise temperatures under load, in traffic, and on hot Aussie or Kiwi summer days. It also protects internal passages, the water pump and the heater core from corrosion and scale, and supports the turbocharger’s thermal management after spirited drives. With the right concentration, it lifts the boiling point, lowers the freezing point, and keeps the system clean so the alloy components and seals live a long, drama‑free life. The result is consistent performance, reliable cabin heating, and reduced risk of overheating that could otherwise lead to expensive repairs.

For servicing, Mitsubishi specifies a long‑life, silicate‑free coolant, owners should follow the schedule in the vehicle’s maintenance booklet. Factory fill long‑life coolants typically have extended replacement intervals (often up to 160,000 km or around 8–10 years, then shorter intervals thereafter), but always go by the local schedule for Australia/New Zealand and the vehicle’s service history. At every service, the level should be checked cold, the condition assessed (colour and clarity), and the system inspected for leaks. When replacing, use the correct pre‑mixed coolant or mix with demineralised water to the specified ratio. Avoid mixing coolant chemistries or colours. Bleeding air properly and running the heater during refilling helps prevent hot spots and fluctuating temps.

• Check the reservoir level monthly or before long trips, top up only with the correct pre‑mix.
• Look for warning signs: rising temps, low heater output, sweet smell, or pink/white residue around hoses.
• Replace aged hoses and clamps during coolant service if they’re soft, cracked, or swollen.
• If towing or driving hard, let the car cruise gently for the last few minutes to help thermal stabilisation.
• Keep records of dates, kilometres, and the exact coolant used.

Popular question: What coolant type does a 2020 Eclipse Cross use?

Mitsubishi specifies a long‑life, ethylene glycol coolant, commonly referred to as Mitsubishi Genuine Super Long Life Coolant Premium (pre‑mixed). If genuine fluid isn’t available, choose a high‑quality, silicate‑free long‑life coolant meeting recognised standards and don’t mix types.

Popular question: How often should the coolant be changed?

Follow the service schedule in the owner’s manual. Many Eclipse Cross vehicles run extended intervals on factory fill (often up to 160,000 km or around 8–10 years), then shorter intervals. Severe use or previous top‑ups with water can shorten the change window.

Popular question: Can regular tap water be used to top up?

Only use the correct pre‑mix or demineralised water. In an emergency, a small top‑up with demineralised water is acceptable, but restore the proper coolant mix as soon as possible. Avoid tap water due to minerals that can cause scale and corrosion.
