Where is my coolant temp sensor on my 1998 blazer?

On a 1998 Chevrolet Blazer, the coolant temperature sensor is typically located on the engine block, near the thermostat housing. It is usually found on the driver's side of the engine, close to the intake manifold. To access it, you may need to remove any obstructing components, such as the air intake duct. Always consult your vehicle's service manual for precise locations and guidance.
