Accurate Aftermarket Coolant Reservoir Tank With Temp Sensor
✔️ 1.8L Capacity Direct Fit Cooling Swap For BMW V8 Models

This aftermarket coolant expansion tank keeps your engine from boiling over when gridlock turns the cabin into a sauna. Designed to bolt straight into stock mounting spots, it swaps out cracked plastic risers without cutting hoses or bending brackets. You get factory level flow control and reliable temp readings for smooth street cruising anytime. Engineers routed coolant internally to minimize external clamp stress, which means fewer drip points when you push the throttle near redline on backroads.

✅ Reference OE codes 17137601948 and 17137575577 for easy catalog lookup
✅ Temperature sensing pin integrates cleanly into the upper housing

💡 What causes cheap coolant reservoirs to crack and leak under heavy loads?

Most inexpensive replacements fracture because makers omit structural glass fibers. You want a tank designed for sustained European V8 heat cycles to keep things handy and trouble free.
