Water Pump Tester Kit 0-15 PSI Cooling System Flow Gauge

A water pump tester kit for checking coolant circulation in situ without removing parts from the vehicle. It uses a low-pressure 0-15 PSI gauge to show the small pressure rises created as coolant moves around the engine block while the engine is running.

Used for cooling system fault finding during vehicle maintenance and garage diagnostics, this kit helps when investigating poor heater performance, suspected circulation problems or general cooling system issues. It suits workshop use as well as home mechanics carrying out servicing and repair work, especially when you want a clearer indication of coolant flow before committing to strip-down.

The kit includes the main analyser components needed for flow checks, with rubber pipe seals, blanking plugs, a 2 part pipe connector body, and a 2 metre nylon hose with male connector. The low-pressure gauge range is suited to reading the smaller pressure changes involved in coolant movement rather than higher-pressure system testing. The hose length gives flexibility when positioning the gauge during checks, and the included sealing and connector parts help with setting the kit up for repeat diagnostic use. A practical option for regular cooling system assessment where quick in-place checks can save time.
