This part number is commonly searched as TS-658 for BMW coolant temperature sender replacement needs.

This part cross-references Walker Products (e.g., 211-2021) for the same application.

What It Is Used For

• Restoring coolant temperature gauge operation
• Replacing a faulty sender that causes inaccurate temperature readings
• Addressing intermittent or no temperature signal at the cluster
• Correcting warning lights related to coolant temperature input
• Servicing BMW cooling system sensor faults on gauge-equipped engines

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Confirm the vehicle’s exact engine and fitment notes, especially for BMW models listed with “With Gauge” or “On Engine” applications. Compare the original sender location and electrical connector to the TS-658 before replacement. For best results, inspect the cooling system connector and surrounding harness for corrosion or damage during service.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TS-658 is cataloged for direct-fit BMW applications and should be matched to the vehicle’s year, model, and fitment notes before installation.
