Buying advice

When buying cooling and water pump tools, consider the primary tasks you need to perform. For leak diagnosis, a pressure tester kit (like OTC 6615) is essential. For water pump removal, strap wrenches (Astro Pneumatic 7851) or pulley pullers (Gates 33009) are helpful. If you're on a budget, basic spill-free funnels (Lisle 24630) and radiator cap testers (OEMTOOLS 24427) offer good value. Professionals may prefer comprehensive vacuum/pressure kits (ARES 70362). Always check adapter compatibility with your vehicle.
