The Snap-on Cooling System Pressure Tester, No. SVTS272A, is designed to pressure test radiator and cooling systems for leak location. The SVTS272A quickly and efficiently achieves required 35 psi with fewer pump strokes than competing units, the company says. The soft grip knob is comfortable and its knurled shank reduces hand slippage while pumping. It includes the four most common adapters and is designed to resemble caps from the systems they test, allowing technicians to confidently examine nearly every car on the road. It also offers an improved clear-view gauge face, red protective boot, and laser marking and includes a protective case.
