Frequently Asked Questions
Founded with the needs of the modern UK workshop in mind, CoolTest was born from a simple frustration: the persistent, time-consuming challenge of diagnosing elusive radiator leaks and the headaches of air-locked cooling systems after routine maintenance. We know that time on the ramp is money, and comeback jobs due to overheating are a mechanic's worst nightmare.
Our flagship 28-piece universal kits are designed to rival the durability of traditional workshop staples like Sealey or Laser Tools, but without the prohibitive price tags or the need to buy separate specialist adapters. We engineered a true 2-in-1 solution that combines precision pressure testing with powerful vacuum purge technology. This ensures that every independent garage, mobile mechanic, and dedicated DIYer has the exact fitment they need for almost any vehicle on UK roads.
At CoolTest, we believe in providing robust, pressure-safe components with clearly calibrated gauges and comprehensive compatibility. Every kit is dispatched from our UK warehouse, backed by a solid 12-month warranty, and designed to help you diagnose faults accurately, refill systems cleanly, and get vehicles back on the road safely.
