Description

Product Details

Keep your cooling system running at peak performance with this OEM‑quality coolant flange, designed to replace worn or brittle factory units. Over time, years of exposure to engine bay heat and hot coolant can cause the original ABS plastic flange to crack, warp, or fatigue. This often leads to coolant leaks, loss of fluid, and even engine overheating.

Replacing the flange is an essential preventative maintenance step to restore proper cooling function and ensure long‑lasting reliability.

🔹 Features & Benefits:

  • Direct replacement coolant flange
  • Manufactured with durable, heat‑resistant materials
  • Prevents coolant leaks and protects against overheating
  • Includes sealing O‑ring for a secure, leak‑free installation
  • Simple, direct fit—no modifications required

⚠️ Note:
If your vehicle has only one temperature sensor on the flange, you will also need plug ES253103 (sold separately).

Protect your engine and restore your vehicle’s cooling efficiency with this dependable coolant flange replacement.
