Product Details

The Stant 12021 Radiator Cap Adapter is a pressure tester accessory designed specifically for testing small diameter radiator caps. This adapter connects to a compatible radiator pressure tester, allowing technicians to accurately verify the release pressure of small-diameter caps commonly found on many import and domestic vehicles.

Key Features:

  • Designed for use with small diameter (45mm OD) radiator caps, including Stant 10227 and 10233
  • Compatible with the Stant 12270 cooling system pressure tester and many other standard pressure testers
  • Simple, no-moving-parts design for reliable, repeatable results
  • Sold individually as a single adapter
  • Backed by a 90-day Stant limited warranty

This adapter is an essential addition to any cooling system diagnostic toolkit. It enables accurate pressure testing of small-diameter radiator caps as found on many late-model Toyota, Nissan, Subaru, Mitsubishi, and Honda vehicles, helping to identify caps that are not releasing at the correct pressure — a common cause of cooling system failures and blown hoses.

Just what I ordered at a great price

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Awesome price! I couldn't find a better bargain anywhere, and I searched for days.

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

Excellent service and the cheapest price that I could find anywhere. Ordered on a Sunday and delivered in record time three days later...basic overground shipping. I will deffinately order from here again!
