Product Details: Transmission Oil Pipe (OE No. 30748822)

This transmission oil pipe (OE No. 30748822) is a critical component in the hydraulic system of Volvo transmissions, designed to circulate transmission oil (ATF) between key components such as oil pumps, valve bodies, and radiators. It ensures smooth hydraulic transmission for gear shifting, lubricates friction parts (e.g., gears, bearings), and facilitates heat dissipation to maintain optimal oil temperature (80-120℃), directly impacting transmission performance and longevity.

Core Specifications

• Material: Constructed with a metal hard pipe (steel/aluminum alloy) for fixed sections near the transmission, and reinforced rubber hoses (inner NBR/FKM rubber, outer braided steel wire) for vibration-adaptive segments. This combination offers high pressure resistance (≥15bar) and temperature tolerance (-40℃ to 150℃).
• Function: Enables stable oil pressure transmission (3-10bar) for seamless gear shifts, prevents oil leakage via O-ring/metal cone seals, and supports efficient heat exchange to avoid oil degradation.

Frequently Asked Questions (FAQ)

Q1: How to determine if the thermostat is faulty?

A1: A thermostat failure usually causes the following symptoms:

Engine overheating: The thermostat is stuck in the closed state, preventing the coolant from entering the radiator.

Slow engine heating: The thermostat is stuck in the open state, and the coolant is always circulating, causing the engine to be unable to reach normal operating temperature for a long time.

Increased fuel consumption: The engine does not work at the optimal temperature, the combustion efficiency will be reduced, resulting in increased fuel consumption.

Q2: What should be paid attention to when replacing the LR062498 thermostat?

A2: It is recommended to be replaced by a professional technician, and pay attention to the following points:

Operate when the engine is cold to prevent burns.

Drain the old coolant correctly.

Make sure the seal is installed in place during installation to prevent coolant leakage.

After replacement, the cooling system needs to be vented to prevent "air blockage" from affecting the cooling effect.
