058 121 058R – Oil Cooler Hose

Description

The 058121058R Oil Cooler Hose serves as a critical hydraulic connection between the engine oil cooler and the coolant return pipe. This molded hose facilitates the steady return of coolant back into the primary cooling circuit, ensuring that thermal energy is effectively dissipated from circulating engine oil. Consequently, maintaining an intact, unrestricted hose assembly preserves vital engine operating temperatures and protects internal lubrication integrity.

Engineered to strict factory specifications, this direct replacement coolant hose matches original factory bends, internal diameters, and connection profiles. Furthermore, its heavy-duty reinforced construction delivers reliable service life under extreme engine bay thermal cycling.

Signs Your Oil Cooler Hose Needs Replacing

Inspect your engine cooling circuit for these common warning signs indicating a degraded return hose:

• Visible surface cracking, checking, or micro-fissures developing across the outer rubber casing.

• Noticeable bulging, swelling, or softness near the oil cooler or metal pipe clamp connections.

• Spongy or collapsed hose sections when squeezed during routine underhood inspection.

• Dried, crusty pink, or blue coolant residue accumulating around the hose barbs and hose clamps.

• Unexplained gradual drops in the coolant expansion tank level without a visible puddle.

• Elevated coolant temperature readings or dash warning lamps during heavy traffic or spirited driving.

Key Features of the 058121058R Oil Cooler Hose

• OE Part Number: 058 121 058 R

• Function: Connects the engine oil cooler to the coolant return hard pipe.

• Material: Multi-layer reinforced high-temperature elastomer resistant to coolant additives and thermal fatigue.

• Design: Precision-molded factory curvature ensures clean routing without kinking or chassis interference.

• Durability: Engineered to withstand cooling system operating pressures and extreme underhood temperature spikes.

• Fitment: Direct OEM-specification replacement requiring no trimming or custom modifications.

Service Notes

Always verify fitment by VIN before ordering. Never service the engine cooling circuit while the system is hot or pressurized, as hot fluid can cause severe burns.

Compatibility

Always verify fitment by VIN before ordering. Compatibility depends on engine displacement, engine code (such as 1.8T longitudinal applications), chassis platform, and original installed hose configuration.
