Parts for your 2014 Mitsubishi Asx-Radiator hose

2014 Mitsubishi ASX radiator hose — purpose, care, and when to replace

Yes, the 2014 Mitsubishi ASX uses radiator hoses. Mitsubishi’s own technical literature—the Mitsubishi Motors Workshop Manual for the GA-series ASX/RVR/Outlander Sport (Cooling System section) and the Mitsubishi ASA electronic parts catalogue for MY2014—lists conventional upper and lower radiator hoses for both petrol and diesel variants. So a radiator hose is absolutely relevant to this model.

The radiator hose does a simple but critical job: it carries coolant between the engine and the radiator, letting heat escape so the engine runs at the right temperature. The upper hose feeds hot coolant to the radiator, the lower returns cooled fluid back to the block. Made from heat- and pressure-rated EPDM rubber, these hoses live a hard life—heat cycles, vibration, and exposure to oil can age them, and failure usually shows up as soft spots, cracking, swelling, or leaks at the clamps.

As part of routine servicing on a 2014 ASX, it’s smart to inspect the hoses at every service interval (about every 12 months/15,000 kilometres). Squeeze them gently when the engine is cold, they should feel firm and springy, not mushy or rock-hard. Check for:

• Cracks, glazing, bulges, or kinks along the hose body
• Coolant crust or staining around hose ends and clamps
• Oil contamination (oil degrades rubber quickly)
• Loose, corroded, or mis-positioned clamps

Replacement timing depends on age, kilometres, climate, and condition. Many owners plan for hoses at around 6–10 years or 100,000–150,000 km, or sooner if any wear signs show. When replacing, it’s good practice to do hoses in pairs (upper and lower), fit quality spring-band or constant-tension clamps, and refresh the coolant with the correct Mitsubishi-approved long-life coolant (often blue). Avoid mixing coolant types and use demineralised water if using concentrate.

1. Only work on a fully cooled engine, relieve pressure by opening the radiator cap carefully.
2. Drain enough coolant to drop below hose level.
3. Remove clamps, twist the old hose to break the seal, and pull it off.
4. Clean the necks, fit the new hose with the arrows/orientation marks aligned, and position clamps behind the bead.
5. Refill, follow the factory bleed procedure, run the heater on hot, and top up as needed. Check for leaks after a proper warm-up drive.

For peace of mind, keep an eye on temperature readings and coolant level under the bonnet over the next few trips. If the ASX tows, sees gravel roads, or works in hot Aussie or Kiwi summers, those checks matter even more.

Popular questions about 2014 Mitsubishi ASX radiator hoses

How often should radiator hoses be replaced on a 2014 ASX?
They should be inspected at every service and replaced based on condition, typically around 6–10 years or 100,000–150,000 km. Harsh heat, lots of stop–start driving, or oil exposure can bring that forward.

What coolant should be used after changing the hoses?
Use Mitsubishi-approved long-life coolant specified in the owner’s manual (commonly a blue long-life type). If it’s concentrate, mix with demineralised water to the correct ratio, don’t mix different coolant chemistries.

Are petrol and diesel ASX radiator hoses the same?
No. Routing and part numbers differ by engine and build (petrol vs diesel, and some market variations). Always match by VIN or engine code to ensure the correct upper and lower hoses and clamps.
