Installation and Operation

Replacing the water pump housing requires precision. Before starting work, ensure the engine is cool and the cooling system is disconnected from the water supply. During installation, pay close attention to the condition of the seals – their correct placement is crucial for the tightness of the entire system. We do not recommend reusing old seals, even if they appear intact, as they may cause leaks shortly after operation. After installing the new SIERRA 118-3363 housing, start the engine and thoroughly check for leaks at the connection point. Regular inspection of the water pump prevents engine overheating, which is one of the most common causes of breakdowns during the season.
