## Overview

The Prestone AF-KIT-6PK Flush 'N Fill Kit is a professional-grade solution designed to flush the entire cooling system of most cars and light trucks.

With quick antifreeze installation and a comprehensive flush process, this kit helps maintain your vehicle’s cooling efficiency and prevents costly engine damage.

## Description

Prestone Flush 'N Fill Kit professionally back-flushes cooling systems of most cars and light trucks on the road today. Easily installs anti-freeze/coolant in minutes. Rust and dirty coolant that circulates in your car’s cooling system can lead to a clogged radiator, resulting in overheating and engine damage. Draining the radiator alone does not sufficiently remove old coolant, as the radiator may contain 40 percent or less of the coolant. The Prestone Flush 'N Fill Kit allows you to professionally flush the complete cooling system, not just the radiator, in one easy process.

### ⭐⭐⭐⭐⭐ 







  
  
    I have installed countless, they have not failed me yet...
  

*by W***2 on Reviewed in the United States 🇺🇸 on February 10, 2023*

I literally could not tell you how many cars I have installed these on.  Most often, they are of the pavement pounding beater variety, in dire need of a flush.  I cannot think of one time when this kit did not do what I expected of it.  Pro-tip(s):  Don't forget to turn your heat on - you do NOT need to have the blower motor on, but turning it all the way into the red ensures you have coolant running through the heater core.  Remove your thermostat for the best results - when you are running cold hose water, that thermostat may never open and you really aren't flushing the entire system.  Only turn the hose on as much as you need - turn it up until it just starts to overflow.  Your hose at full blast can be 45 to even 80psi, your cooling system runs at just 15psi.  If your heater core is at the end of its life, 45psi can do it in.  If you do blow your heater core out, don't blame this kit - your core was months away from blowing out all on its own!

    If you know what your doing it's simple to use.

Product was sturdy, instructions were a little vague.

    Be Careful If This is Safe to Use on Your Vehicle
  

*by S***N on Reviewed in the United States 🇺🇸 on March 1, 2023*

I bought this to flush the cooling system of my 2010 Ford Fusion but after watching some YT videos it is not recommended to do the sort of flush I had in mind using this product. Don't get me wrong, the product is totally fine and useful for 'older' vehicle cooling system flushing but some modern vehicles needs special procedures (my 2010 Fusion needs to be evacuated and filled using a vacuum type of device) so look before you buy.
