Parts for your 2025 Mitsubishi Eclipse cross-Radiator

2025 Mitsubishi Eclipse Cross Radiator

Yes, a radiator is absolutely fitted to the 2025 Mitsubishi Eclipse Cross. Technical documentation for recent Eclipse Cross models—such as Mitsubishi Motors’ workshop manuals for the 1.5‑litre turbo petrol (liquid-cooled) and the Eclipse Cross PHEV service information—specifies an aluminium cross‑flow radiator as part of the engine cooling system. The PHEV also uses dedicated cooling circuits for the hybrid components alongside the engine’s conventional radiator, as outlined in Mitsubishi service literature and owner’s manuals for the platform.

For everyday owners, that radiator’s job is simple but critical: it sheds heat from the engine coolant so the 1.5T petrol or the PHEV’s petrol engine stays smack in its ideal temperature window. That means stable performance, better fuel economy, and long engine life—especially important in Aussie and Kiwi conditions with long climbs, towing, or stop‑start city traffic under the bonnet’s heat soak.

When it comes to servicing, the radiator and coolant deserve routine attention. At each scheduled service, a tech should check coolant level and condition, inspect the cap and hoses, and look for any traces of seepage around end tanks and fittings. Follow the maintenance schedule in the service book for coolant replacement intervals, using Mitsubishi‑approved long‑life coolant in the correct concentration. For PHEV variants, note there can be separate coolant loops—high‑voltage system cooling should only be handled by trained technicians.

• Watch for warning signs: temperature creeping up on hills, coolant loss, dried crusty residue near the radiator, discoloured or sludgy coolant, or a sweet smell after shutdown.
• If overheating occurs, don’t keep driving—have the system pressure‑tested to pinpoint leaks, cap issues, or a blocked core.
• When replacing a radiator, it’s smart to fit a new cap, fresh coolant, and consider a thermostat and upper/lower hoses if they’re aged.
• After any cooling work, ensure a proper bleed to remove air pockets, and verify fan operation.

A healthy radiator helps the Eclipse Cross run cooler, last longer, and keep its spirited feel. Sticking to the right coolant, tidy hosework, and timely inspections goes a long way—whether it’s a school run in Auckland or a summer road trip across regional NSW.

Popular questions

What coolant should the 2025 Eclipse Cross use?
Mitsubishi specifies a long‑life, ethylene‑glycol coolant that meets the manufacturer’s standards. Use the recommended pre‑mix or mix with demineralised water to the ratio stated in the handbook. For PHEV models, only use the specified coolant for each circuit.

How often should the coolant be changed?
Follow the service schedule in the owner’s manual or service booklet. Long‑life coolant typically has extended intervals, but harsh conditions, towing, or prior overheating can shorten that. A technician can test coolant condition and advise if an early change is wise.

What are signs the radiator needs replacement?
Persistent leaks around the end tanks, repeated overheating, visible fin corrosion or damaged cores, and internal blockage (poor flow on pressure testing) point to a replacement rather than a repair. Pair the job with new hoses and a cap for best results.
