Parts for your 2024 Mitsubishi Eclipse cross-Radiator

2024 Mitsubishi Eclipse Cross radiator: what it does, and how to look after it

A radiator is absolutely fitted to the 2024 Mitsubishi Eclipse Cross and it’s central to the vehicle’s liquid-cooling system. This is documented in Mitsubishi Motors technical materials including the 2024 Eclipse Cross Owner’s Manual (Cooling System section), the Mitsubishi workshop manual for the 1.5‑litre turbo petrol (4B40) and PHEV powertrains (cooling chapters), and Mitsubishi’s ASA/parts catalogue which lists the radiator assembly and associated hoses, fans, and cap for 2024 models. The PHEV variant also uses additional heat exchangers for the hybrid system, but the conventional engine radiator remains a key component.

What does it do? The radiator sheds heat from the engine coolant, keeping operating temperatures in the sweet spot for performance, reliability, and emissions. Coolant cycles through the engine, absorbs heat, then passes through the radiator where air flow and electric fans pull that heat away. It also works in tandem with other front-end heat exchangers, like the A/C condenser and, on some specs, transmission or hybrid coolers.

Looking after the Eclipse Cross radiator is straightforward and fits neatly into regular servicing:

• Check coolant level and condition at each service. Top up only with Mitsubishi‑approved long‑life coolant, pre‑mixed to the right ratio as per the owner’s manual.
• Inspect the radiator cap, hoses, clamps and the plastic end tanks for seepage, crusty residue, or swelling. Replace any tired components before they become a drama.
• Keep the grille and the front of the radiator clear of leaves, bugs and road grime for healthy airflow. Never blast fins with high‑pressure water—use gentle rinse and a soft brush.
• Follow the logbook for coolant change intervals. If a flush is due, use the correct bleed procedure to avoid air pockets and overheating. A vacuum fill tool is ideal.

When it’s time to replace the radiator—because of leaks, impact damage, or persistent overheating—opt for quality OEM or equivalent, new cap and fresh hoses. Pressure‑test after installation, confirm fan operation, and road‑test to temperature. For PHEV models, note there are multiple cooling circuits, stick to the factory procedure and, for any high‑voltage components, leave it to a trained technician.

Tell‑tales the radiator needs attention include rising temps under load, sweet coolant smell, pink/green residue around end tanks, low coolant without obvious external leaks, or gurgling sounds after shut‑down.

Does the 2024 Eclipse Cross (petrol and PHEV) actually have a radiator?

Yes. Both the 1.5‑litre turbo petrol and the PHEV use a conventional engine radiator. Mitsubishi documentation (owner’s manual, workshop manual, and parts catalogue) details the radiator, fans, hoses, and cap, and the PHEV adds extra cooling hardware for the hybrid system.

What coolant should be used, and how often should it be changed?

Use Mitsubishi‑approved long‑life coolant as specified in the owner’s manual, typically supplied pre‑mixed. Don’t mix different coolant chemistries or colours. Inspect level and condition at each service and change coolant as per the logbook for your market and variant.

What are the common signs the radiator needs replacement?

Look for persistent overheating, visible leaks or staining at the end tanks, a perished cap or hoses, low coolant with no clear external leak, or repeated need to top up. After any front‑end impact, have the radiator and condenser checked for fin damage and core integrity.
