Parts for your 2017 Mitsubishi Asx-Radiator

2017 Mitsubishi ASX radiator — purpose, care, and replacement

Based on technical references including the Mitsubishi Motors Service Manual for ASX/Outlander Sport (Group 14 – Cooling), the Mitsubishi Electronic Parts Catalogue (EPC) listings for 2017 model-year ASX petrol and diesel variants, and the factory Owner’s Manual cooling-system instructions, the 2017 Mitsubishi ASX is fitted with a conventional liquid-cooling system that uses a front-mounted aluminium radiator (some variants also incorporate a transmission fluid heat exchanger). So, yes—the radiator is very much relevant and used on the 2017 ASX.

The radiator’s job is simple but critical: it sheds engine heat. Coolant absorbs heat from the engine, runs through the radiator’s core, and the airflow (with help from electric fans) pulls that heat out. Keeping temperatures stable protects the head gasket, plastic housings, sensors, and the CVT or auto trans cooler where fitted. Skipping radiator care can turn a small leak or blocked core into a costly overheat.

As part of servicing, regular cooling-system checks pay off. Radiator fins should be clean and straight for good airflow. Coolant needs to be the correct spec (Mitsubishi SLLC/HOAT-style, typically blue) and the system should be free of air. On higher‑kilometre ASX vehicles, the plastic tank crimps and hose necks can age—worth a close look under the bonnet. When replacing a radiator, choose the right core thickness and outlet layout for the ASX engine/trans variant, swap over the fan shroud and sensors carefully, and always pressure‑test before calling the job done.

• Inspect coolant level/condition at each service, look for leaks, staining, or a sweet smell.
• Keep fins clear of bugs and road grime, avoid high‑pressure spray directly at the core.
• Replace the cap if it won’t hold pressure, a weak cap invites boil‑over.
• Flush and refill with the correct coolant at sensible intervals, using demineralised water if mixing concentrate.
• Bleed air properly after any cooling work, watch the temp gauge on the first drive.

If the ASX runs hotter than normal, the heater blows cool at idle, or the fans are on constantly, it’s time for a system check. A fresh radiator restores stable temps, protects the alloy head, and keeps daily driving drama‑free.

Popular questions

What coolant does a 2017 ASX use, and how much does it take?

The 2017 ASX is designed for Mitsubishi Super Long Life Coolant (blue), an ethylene‑glycol, long‑life type. Capacity varies by engine and whether the heater/core is drained, generally in the 6–7 litre range. Stick with the same type and colour, mixing coolants can shorten service life.

How often should the coolant be changed?

Have the cooling system checked at every service and replace coolant on a time/kilometre basis appropriate for local conditions—many workshops recommend about every 5 years or 100,000 km, or sooner if the coolant is discoloured or contaminated. Follow the factory schedule where available and always bleed air on refill.

What are common signs the radiator needs attention?

Overheating, low coolant, white crust around joins, discoloured coolant, or a sweet smell are classic flags. On CVT models with an integrated cooler, milky fluid or temp warnings also warrant immediate inspection to protect the transmission.
