The Kohler AEGIS LH775 is a high-performance, liquid-cooled, horizontal-shaft V-twin engine. Unlike the air-cooled Kohler Command series, its liquid-cooling system provides more consistent temperatures, which results in better power, improved fuel economy, and a longer engine life.

This engine is commonly found in commercial and heavy-duty equipment, such as utility vehicles, industrial machinery, and agricultural equipment. It is equipped with advanced features like Electronic Fuel Injection (EFI) for easier starting and a more efficient fuel burn.

Common problems

Although the LH775 is a robust engine, potential issues are often related to its fuel and cooling systems.

Starting issues: Problems with starting are often related to the EFI system, such as a faulty fuel pump relay, a bad speed sensor, or a throttle position sensor.
Fuel system faults: Failures of the electronic fuel pump or blockages in the fuel system can cause rough running, sputtering, or a loss of power.
Cooling system issues: Although liquid-cooled, problems can occur with the water pump or heat exchanger, which may lead to overheating if not addressed.
Oil leaks: As with many engines, aging gaskets or seals can eventually lead to oil leaks.

Replacement parts and manuals

Due to its commercial applications, parts for the LH775 are readily available from power equipment retailers.

Short Blocks: New short block assemblies, such as the Kohler 66 522 13-S, are available for purchase.
