Parts for your 2014 Mitsubishi Asx-Radiator

2014 Mitsubishi ASX Radiator — What it does and how to look after it

Yes, the 2014 Mitsubishi ASX uses a radiator. Technical documentation backs this up: the Mitsubishi Motors Service Manual for ASX/RVR/Outlander Sport (GA#W series, 2010–2015) details the liquid-cooled system with an aluminium crossflow radiator and electric fans, and the Mitsubishi ASA electronic parts catalogue lists specific radiator assemblies for 2014 ASX variants (petrol, diesel, manual, and CVT). Reputable aftermarket catalogues in AU/NZ also carry direct-fit radiators for this model, confirming it’s a standard, essential component.

The radiator’s job is simple but vital: it sheds the engine’s heat. Coolant absorbs heat in the engine, flows through the radiator, and dumps that heat to the air with help from the fans and vehicle speed. It works with the thermostat and water pump to keep the ASX in its happy temperature zone, ensuring smooth performance, good fuel economy, and long engine life.

As part of servicing a 2014 ASX, it’s smart to keep an eye on the radiator and the whole cooling system. Look for tell-tales like rising temperature under load, a sweet coolant smell under the bonnet, staining or white crust around end tanks, damp patches on the undertray, or discoloured/sludgy coolant. Poor cabin heater output can also point to low coolant or air in the system.

Coolant should be refreshed in line with the logbook—commonly around every 5 years or about 100,000 km, depending on the exact engine and market schedule. Use the correct Mitsubishi long-life coolant (often the blue SLLC) and don’t mix types. If using concentrate, mix with demineralised water. When refilling, bleed the system properly: run the engine with the heater on hot, top up via the correct point, and check for airlocks. A new pressure cap (around 0.9–1.1 bar) and fresh radiator hoses are cheap insurance if the originals are ageing.

When replacing the radiator, choose a quality unit matched to your drivetrain. Many ASX CVT/auto models route transmission fluid through an integrated cooler in the radiator—so cap lines when swapping, use new sealing washers, and check for any signs of cross-contamination. Reuse fan shrouds carefully, avoid fin damage, and inspect the thermostat, water pump weep hole, and cooling fans while you’re there. After the job, pressure-test, verify the fans cycle correctly, and dispose of old coolant responsibly.

• Top up only with the correct spec coolant
• Keep fins clear of debris and bugs
• Check hoses, clamps, and the cap at every service

Popular questions about the 2014 Mitsubishi ASX radiator

How often should the coolant be changed on a 2014 ASX?

Follow the vehicle’s service schedule, many ASX models call for coolant replacement roughly every 5 years or around 100,000 km. Heavy towing, lots of stop–start city driving, or harsh climates can justify earlier changes. Always refill with the Mitsubishi-approved long-life coolant and avoid mixing different types.

What are common signs the radiator needs attention?

Watch for rising engine temperature, frequent cooling-fan operation, visible leaks or dried coolant residue on end tanks, low coolant levels, a sweet smell under the bonnet, discoloured/sludgy coolant, or weak cabin heat. Any of these warrant inspection and, if needed, pressure testing.

Is it safe to drive with a small radiator leak?

Not recommended. Even a slow leak can quickly lead to overheating and serious engine damage. For CVT-equipped ASX models, a cooler leak can also risk transmission-fluid contamination. If a leak is suspected, top up only to get off the road and organise a tow rather than driving on.
