Fitment Notes

  • Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.

Installation / Use / Maintenance Tips

  • Compare the new expansion tank to the removed unit before installation to confirm port positions, cap fitment, and mounting geometry match.
  • Transfer the existing water level sensor from the old tank, or order the sensor separately if required.
  • Inspect related hoses, clamps, and the cap seal for wear before fitting the new tank.
  • Fill with the correct coolant mixture specified for the application and bleed the cooling system fully. Do not overfill — fill only to the marked level.
  • After installation, check for leaks and verify correct coolant level during a warm-up cycle.

Centurion D5 - no more official support.

Since the Centurion D5 isn't supported at all anymore by Centurion Systems, I bought this scarce item as a "backup" for the day I need it. (Along with refurbished D5 CP80 controller, from another supplier though.)
Much easier to replace just the gate sensor & harness - or CP80 - than de-wire / re-wire all connections than replacing the entire D5 gate motor!
Arrive perfectly & securely wrapped and courier service was very quick.
Thank you!

Great Quality Cup Handle – Stylish and Well Made

Excellent quality cup handle with a clean brushed satin nickel finish. It feels sturdy, was easy to install, and gives cabinets and drawers a modern, premium look. The 64mm size fit perfectly, and the finish looks great while helping to hide fingerprints. Very happy with the purchase and would definitely recommend it.
