Oil Cooler

Oil Cooler — Heat Control in the Gearbox System

The oil cooler is a component located within the subgroup of the gearbox system in heavy commercial vehicles, transferring the heat generated by the gearbox oil during operation to the outside environment and keeping the oil within its ideal temperature range. Inside the gearbox, gear sets and clutch elements generate intense heat through friction; if this heat is not dissipated in time, it degrades the oil's viscosity, reduces lubrication performance, and accelerates gear wear. The oil cooler steps in at exactly this point, contributing to the long-lasting and efficient operation of the gearbox.

The product range includes complete air-cooled and liquid-cooled oil coolers, cooler core assemblies, connection hoses and fittings, gaskets and sealing elements, as well as supporting parts such as thermostats and pressure valves on the cooler. This wide product range offers solutions suited to both complete replacement and the individual renewal of a faulty component.

• Complete oil cooler assemblies and cooler core
• Connection hose, fitting and pipe elements
• Gasket, o-ring and sealing sets
• Thermostat and pressure control valves

When selecting an oil cooler, the vehicle's gearbox type and cooling capacity needs should be taken into account, and a part with the correct dimensions and connection structure should be chosen with general compatibility with major truck and bus brands in mind. As part of regular maintenance, checking the cooler core for blockage and inspecting the sealing of hoses and gaskets is important for the overall health of the gearbox. Evaluating the oil cooler together with other parts in the gearbox category and selecting the right one is a good starting point for those who want to preserve the vehicle's performance when browsing product options.

Frequently Asked Questions

What is an oil cooler? It is a component located within the subgroup of the gearbox system that transfers the heat generated by gearbox oil during operation to the outside environment, keeping the oil at its ideal temperature.

What are the symptoms of oil cooler failure? Overheating in the gearbox, stiffness during gear shifts, a drop in oil level, and leakage around the cooler are among the typical symptoms of a faulty oil cooler.

When should the oil cooler be replaced? The oil cooler should be replaced when the core is blocked, the housing is cracked, continuous leakage is observed, or the gearbox experiences chronic overheating issues.

How is the correct oil cooler selected? The correct oil cooler is determined by choosing a part suited to the vehicle's gearbox type, cooling capacity needs, and connection dimensions, with verified general compatibility.

How is the oil cooler related to other gearbox parts? The oil cooler works together with components such as the gearbox unit, gear shift tube, position sensor, and neutral position valve, contributing to the gearbox functioning at a safe and balanced temperature.

How is oil cooler maintenance performed? The outer surface of the cooler core should be cleaned against blockage, and hose and gasket connections should be checked regularly for sealing.

What happens if the oil cooler is not installed? The gearbox oil overheats excessively, loses its lubricating properties, and this can lead to accelerated wear on gear sets and clutch elements.
