Upper Filler To Radiator Hose 1370A138 For Mitsubishi Outlander ZG ZH 4B12 2.4L

Upper Filler to Radiator Hose — Mitsubishi Outlander ZG ZH 4B12 2.4L

New aftermarket upper coolant hose (filler neck to radiator) to suit the Mitsubishi Outlander ZG and ZH series with the 4B12 2.4L petrol engine (November 2006 – November 2012).

Radiator hoses degrade over time — swelling, cracking, and splitting under heat and pressure. A failed hose can cause rapid coolant loss and engine overheating. Replace yours before it becomes a roadside emergency.

Frequently Asked Questions

Will this hose fit my Mitsubishi Outlander ZG or ZH?
Yes — this hose is designed to fit the Mitsubishi Outlander ZG and ZH series with the 4B12 2.4L petrol engine, built between November 2006 and November 2012, in both FWD and AWD variants. Always confirm your chassis code and build date before ordering.

Is this a genuine Mitsubishi part?
No — this is a quality aftermarket replacement part, not a genuine Mitsubishi OEM component. It is manufactured to equivalent specifications and is cross-referenced to OEM part number 1370A138.

What is the difference between this hose and part 1370A137?
Part 1370A137 is the upper radiator hose (from the engine to the radiator). This part (1370A138) is the upper filler neck to radiator hose — a separate hose in the same cooling circuit. Both are required for a complete upper hose replacement on the ZG/ZH Outlander.

Are clamps included?
No — clamps are not included. Reuse your existing clamps if they are in good condition, or purchase new clamps separately.

What warranty is included?
This part comes with a 12-month warranty against manufacturing defects.

How do I know if my radiator hose needs replacing?
Common signs include visible cracks or swelling in the hose, a coolant smell under the bonnet, coolant puddles under the vehicle, or the engine running hotter than normal. If in doubt, have your cooling system inspected by a qualified mechanic.
