Oil cooler inlet hose for Land Rover Engine oil coolant tube OE LR001442 Oil cooler upper hose

Product Description:

Oil coolant inlet hose

OE NO.: LR001442

Applicable vehicle type: For Land Rover

The oil cooler inlet hose connects the engine to the oil cooler, serving as the primary conduit for delivering uncooled hot engine oil to the cooler. As the first channel in the oil circulation cooling system, it ensures high-temperature oil efficiently enters the cooler for heat exchange, maintaining oil temperature within the optimal operating range.

1. Positioned between the engine lubrication system and the oil cooler, it transports high-temperature oil to the cooler for heat exchange before returning via the return line to the oil pan or main oil gallery.
2. This high-pressure, high-temperature hose typically operates at 0.3-0.8 MPa system pressure, with instantaneous peaks reaching 1.5 MPa. Oil temperatures commonly range from 100-150°C, rising to 180°C during brief periods in turbocharged vehicles.
3. Leaks can cause sudden oil pressure drops, engine cylinder scoring, or even vehicle fires, making it a critical safety component.
