Jeep has heat now! This product worked perfect for my situation

This product worked perfectly for me! I have a Jeep Wrangler and I needed to flush out my heater core. I know there's lots of ways you can do it. You could simply use a garden hose, but this worked better. It really does give lots of pressure and just where you need it and it fits into the heater hose much better than a garden hose ever would. The garden hose sprays all over me and the engine and everywhere else because it doesn't actually fit in the heater hose. This coolant system flush gun fit inside the hose so there was no mess. It worked perfectly. It only took me a couple of minutes once I had everything hooked together I put together end of my heater hose into a bucket cause I really did want to see what would come out and I was surprised. I was really surprised how much dirt and settlement was sitting in my heater core. I was having intermittent problems getting heat from my jeep all winter long and I had a feeling I knew exactly what it was since this seems to be a typical problem for Jeep owners and sure enough this coolant system flush gun fix the problem immediately right away. I had way more heat than normal. This thing worked great for me. It's easy to set up and it's inexpensive. It's not one of those things you're gonna use every day but if you need to flush out your cooling system and everybody does at some point if you keep your car for a long time, this is the perfect companion and I would absolutely purchased it again for the price and the quality and the ease of use I'd say this is a five star product 100%.
