Essential DIY Tool for Car Owners—Engine Coolant Flush Kit

Here’s the general process:

1. 1. Open the drain port or remove the lower hose to empty the old coolant
   2. Connect the cooling system flush kit
   3. Run clean water or flushing solution through the system
   4. Stop once the discharged water looks clear
   5. Use a cooling system vacuum filler to create vacuum inside the system
   6. Refill with fresh coolant under vacuum
   7. Start the engine and verify circulation

It’s straightforward, cleaner, and far more efficient than old-school methods.
