Worked

ghettomute November 9, 2024

the flush and fill worked out great. i suggest you purchase new hose when your done flushing remove the hose you cut and replace with new hose before refilling cooling system. this item is made of plastic and it will be the weak link if you leave it.

Not bad for what it is

Brandon November 3, 2024

If ur trying to flush system an want to catch every drop of fluid this is a must. If ur using buckets sn drums this may be more trouble than worth. It's good quality an comes with more than enough an extra fittings to be compatible with most cooling systems

It works as described. I have a car that's been sitting 20 years the antifreeze looked more like mud than coolant , it now is clear.

I bought this because I thought I needed it to flush a radiator, but I just didn't know any better. Turned out to be completely useless for my vehicle. Perhaps other types of vehicles are able to use this somehow. For me, it was a waste of money. But it didn't cost that much and it was my fault for not knowing what I was doing, so I can't give them a horrible rating.

Good Substitute for an Airlift Kit But Slower

William February 13, 2025

Without an airlift kit to flush the engine and radiator in order to throughly remove air bubbles and debris, I recommend this kit. HoweverTAKE NOTE that using this product requires installing the enclosed T-valve that requires the user to cut in half the secondary relief hose leading off the radiator. Personally I don't like having to alter such an important hose, as doing so increases the potential for a later leak from such a new connections. Plus, using this kit will be much more time consuming, while awaiting for a complete and thorough flush of the engine block, as compared to using an airlift kit, which will flush and refill the entire system within minutes. But, like I said, if an airlift kit isn't available, this kit is the next best thing to ensure a proper flush. ALSO NOTE that in order to use this kit you must connect a water hose. Tap water can damage the cooling system of any car, due to minerals and contaminants present in any tap water. It's HIGHLY RECOMMENDED after evacuating the old coolant, and flushing with a garden hose, to use an adequate coolant cleaner to thoroughly remove all traces of tap water from the cooling system BEFORE adding new coolant!!
