MR127441 Mitsubishi TANK ASSY,RADIATOR C, Price: 36.05$, Weight: 0.435kg

Radiator Coolant Expansion Reservoir for Mitsubishi SUVs and Pickups

Protect your engine with a precise-fit coolant overflow reservoir . This tank stabilizes pressure and fluid volume: when the engine heats up, expanding coolant is routed from the radiator into the bottle; as it cools, vacuum pulls coolant back, keeping the core full and air out. Built to OE geometry (ref MR127441) for correct hose routing and secure mounting.

Why this part is needed

Heat cycles and age make old plastic brittle. Cracks, warped necks, or loose ports cause leaks and pressure loss. Replacing the reservoir restores a sealed cooling system, steady temperature control, and clear level checks ️.

How it works

The cap’s overflow path sends hot coolant to the tank. When the engine cools, negative pressure returns fluid to the radiator, purging air and maintaining optimal fill ️.

What happens if it’s broken

Expect overheating, low coolant, air pockets, weak cabin heat, and possible head gasket damage. Signs include sweet smell, puddles, and dried white stains near the bottle.
