Parts for your 2020 Mitsubishi Eclipse cross-Radiator

2020 Mitsubishi Eclipse Cross radiator — what it does and how to look after it

Yes, the 2020 Mitsubishi Eclipse Cross absolutely uses a radiator. Mitsubishi’s Eclipse Cross Workshop Manual (Group 14 – Cooling) and the Mitsubishi Genuine Parts/EPC listings for the GK/GL series specify a pressurised, liquid-cooled system with an aluminium crossflow radiator, electric fans, thermostat, and expansion tank. Whether running the 1.5L turbo-petrol with CVT or market-specific 2.0L petrol, the radiator is a core cooling component on this model.

The radiator’s job is simple but critical: it pulls heat out of the engine coolant and dumps it into the air flowing through the fins. That keeps engine temps stable under the bonnet, protects the turbo on 1.5T variants during hard pulls, and helps maintain oil and emissions control performance. On some trims, the cooling package also works with a transmission heat exchanger or separate CVT cooler to keep drivability smooth in Aussie and Kiwi summers.

As part of regular servicing, the radiator and cooling system deserve a quick once-over. They’re not high-drama parts when looked after, but neglect can get expensive fast. A good workshop will check for leaks, clogged fins, fan operation, cap condition, and hose integrity, and will test the coolant’s protection level. Coolant should be Mitsubishi-approved long-life type, mixing chemistries is a no-go. Follow the service schedule in the owner’s manual for change intervals, and top up only when the engine is cold.

• Watch for tell-tales: rising temp gauge, sweet coolant smell, pink/green residue on tanks, low reservoir level, or the fans running constantly.
• Keep the condenser and radiator fins clear of bugs and debris — a gentle hose from the engine side out does wonders.
• Replace ageing hoses and the cap proactively, especially past high kilometres or after any overheating episode.

Needing a replacement radiator? Quality, vehicle-specific units will drop into the factory mounts. A proper job involves draining coolant, disconnecting the fans and hoses (and any cooler lines if fitted), lifting the radiator straight up, vacuum-filling fresh coolant, bleeding the system, and confirming fan cut-in and thermostat behaviour. After installation, a pressure test and a road test under load (A/C on, hills if possible) help confirm it’s spot on. Using the correct coolant mix and renewing the cap seals confidence in long-term reliability.

FAQs

Does the 2020 Eclipse Cross have a radiator?
Yes. Mitsubishi’s Workshop Manual (Cooling section) and the Mitsubishi Genuine Parts/EPC for the GK/GL Eclipse Cross specify an aluminium radiator as part of the factory liquid-cooling system.

When should the coolant be changed?
Follow the maintenance schedule in the owner’s handbook for the market and engine fitted. Many late-model Mitsubishis using long-life coolant go long on the first change, then shorter intervals thereafter. Always use Mitsubishi-approved coolant and avoid mixing types.

Can a capable DIYer replace the radiator at home?
It’s doable for a confident DIYer with proper tools, but using a vacuum filler and following the bleed procedure from the workshop manual is key. If the vehicle has auxiliary cooler lines, cap them cleanly and torque fittings to spec. Dispose of old coolant responsibly.
