2016 Mitsubishi ASX Radiator — What It Does and How to Look After It

According to Mitsubishi Motors’ 2016 ASX/Outlander Sport service manual (Cooling System section) and the Mitsubishi ASA electronic parts catalogue, every 2016 Mitsubishi ASX variant—petrol and diesel—uses a conventional liquid-cooling system with an aluminium radiator. It’s an essential component, not an optional extra.

The radiator’s job is straightforward: carry heat away from the engine coolant and dump it into the airstream. In the ASX, an aluminium core with fine fins is paired with electric cooling fans and a thermostat to keep operating temperature steady, helping performance, economy, and engine longevity. On many automatic/CVT models, the radiator assembly also interfaces with a transmission fluid cooler, so it’s a doubly important bit of kit.

As part of regular servicing (as outlined in the ASX owner’s manual maintenance schedule), technicians check coolant level and condition, inspect the radiator cap, hoses and clamps, look for leaks or crusted residue, and make sure the fans kick in at the right temperature. Using the correct Mitsubishi-approved, silicate-free long-life coolant is critical, mixing types can cause gelling or corrosion. Coolant service intervals depend on the exact engine and market guidance, but many AU/NZ workshops follow time-and-kilometre triggers—owners should stick to the schedule shown in their handbook.

When a radiator needs replacement—due to impact damage, corroded tanks, or persistent leaks—best practice includes:

• Draining coolant and safely disposing of it, then disconnecting upper/lower hoses, fan shroud and, where fitted, transmission cooler lines.
• Inspecting the thermostat, radiator cap and hoses, it’s wise to replace tired hoses and the cap at the same time.
• Refilling with the correct premix and bleeding air from the system with the heater on hot, verify both fans cycle and check for leaks under pressure.

Telltales that an ASX radiator needs attention include rising temperature under load, sweet coolant smell, dampness around end tanks, visible fin damage, brown or milky coolant, and repeated low coolant warnings. Ignoring these signs can spiral into overheated heads, warped gaskets and expensive repairs—far costlier than timely radiator work.

For ASX owners in Australia and New Zealand, regular cooling-system checks, genuine or high-quality equivalent parts, and correct coolant go a long way to keeping the 2.0 petrol or diesel engines happily in the green under the bonnet.

Popular questions about the 2016 Mitsubishi ASX radiator

What coolant type and how much does the 2016 ASX take?
Mitsubishi specifies a long-life, silicate-free ethylene glycol coolant that meets its OEM spec, many variants are filled with premixed “Super Long Life” style coolant. Capacity varies slightly by engine and whether the heater core is fully drained, but it’s typically around the mid-6 litre range. The exact figure and spec are listed in the owner’s manual and service manual for the specific engine code.

How often should the coolant be changed?
Intervals depend on the exact coolant and engine, so the owner’s manual schedule is the best guide. In AU/NZ practice, workshops commonly service long-life coolant at roughly 4–5 years or around 80,000–100,000 km, then at shorter intervals thereafter. If the coolant is discoloured, contaminated or the system’s been opened for major work, change it sooner.

Is it okay to drive with a leaking radiator?
It’s risky. Even a slow leak can become a rapid one, leading to overheating and potential head gasket or transmission damage (on models with integrated trans coolers). If there’s active leaking, overheating, or a low-coolant warning, it’s safer to stop and arrange a tow rather than drive on.
