In the Volvo S40, the coolant temperature sensor is typically located near the thermostat housing. It is usually positioned on the engine block, often on the cylinder head or near the intake manifold. Accessing it may require removing some components for better visibility, depending on the specific engine model and year. Always consult the vehicle's repair manual for precise location and removal instructions.

For a 2001 Volvo S40, it is recommended to use a 50/50 mixture of Volvo Genuine Antifreeze/Coolant (which is typically orange or green) and distilled water. If Volvo coolant is unavailable, you can use a high-quality ethylene glycol-based coolant that meets the specifications of ASTM D3306. Always ensure to check the owner's manual for specific recommendations and guidelines. Additionally, avoid mixing different types of coolant to prevent chemical reactions.
