Cooling-System Pressure Testers

Our pick

CTA Manufacturing 9376 - Adjustable Radiator Pressure Tester Kit

Choose the CTA Manufacturing 9376 for a first cooling-system tester with tapered adapters.1

Why this one

  • The CTA 9376 includes a pump and gauge, so you are buying a testing kit rather than an adapter pack for a pump you already own.1
  • Its four included adapters use a tapered fitting approach; check their fit against your vehicle’s filler neck before buying.12

The alternatives

Other contenders

  • ATD ATD-3302

    Choose the ATD 3302 if you prefer make-specific adapters and can confirm the exact fitting for your vehicle.36

For your first cooling-system tester

A first tester needs the pump and connection adapters together, rather than an adapter-only pack.1 Choose the CTA 9376 complete kit if its tapered adapters match your vehicle’s filler neck.1

For testing the radiator cap itself

A radiator-cap test function matters when you want to test the cap as well as the cooling system.7 Choose the FJC 43645 when radiator-cap testing is a priority and its listed vehicle adapters match your application.57
