The cooling system test kit for passenger cars is ideal for pressure testing, leak testing, and leak detection on the cooling systems of modern passenger cars from numerous European and Asian manufacturers. The cooling system tester with a quick-connect coupling allows for the rapid connection of universal and individual adapters. The integrated drain valve enables the test pressure to be released safely and in a controlled manner.

The ergonomically shaped pump body is made of glass-fiber-reinforced plastic and is designed for daily workshop use. The NG 52 precision pressure gauge with a robust rubber protective cap features a dual-range scale (0–2.5 bar / 0–36 psi) and allows for precise monitoring during testing. The selection of radiator adapters / coolant adapters is based on the vehicle generations of recent years from European and Asian vehicle manufacturers. In total, the test kit includes six connectable adapters, three of which are angle adapters (KW..) for testing situations with limited space in the engine compartment.
