I like the hose over all – I did have a slight problem during install on my 2007 Chevy Silverado 2500 HD – I could not get the aluminum collar to fit onto the lower port of my radiator. The install video makes it look VERY easy, just “pops” on.So – I called customer service, and they were willing to send me a brand new kit – just because I was having problems installing. I was VERY surprised.What I finally got to work – the customer support guy was helpful, but I had to take the chance at what I did. I had to use a heat gun to heat up the gasket inside the aluminum collar – and the plastic port on the lower part of the radiator – and it finally “popped” into place. I installed this hose right before Christmas 2017 (so today is 3 April 2018) no problems so far – almost 4 months old.The only reason why I put 4 stars is because that collar was hard to install. Of course the video didn’t actually have the radiator mounted in a vehicle, therefore possibly being WAY easier to install when on a bench instead of on a vehicle.

Hose quality is great, parts quality is great, part fitment? Absolute hot garbage. I wouldn’t buy this for again if it was on sale HALF OFF. I cannot even tell you how much stress and frustration the lower stainless coupler caused me. The other review said pain in the ass, I say it is impossible unless you pull the radiator and beat it on with a hammer. I tried insane amounts of heat, lube, oil, hammer, I tried everything I could imagine to get this lower coupler to fit. I probably spent 7 HOURS trimming the internal o-ring that sits inside the stainless coupler that connects to the passenger side radiator outlet. I probably had to shave away over half of the o ring to BARELY get it to fit. Even though I shaved half of it away with a file, I still had to use every muscle in my body to twist and squeeze and slide the coupler on with half the o ring being gone. I can ASSURE you it’s too large because after install it doesn’t leak a drop.I have had nothing but good things to say about mishimoto up until this point. I have bought parts and hoses from them for years for other vehicles with absolutely no complaints. They need a serous quality assure check with their diesel products, this caused me incredible amounts of unneeded blood sweat and tears.

To those who will purchase. When you get ready to install, make sure to remove the plastic wheel well cover on the passenger side. Slide the driver side of hose through first, down and around and up to connection point. I tried from underneath,and take my word for it, that duck dont hunt. Other than that. Awesome product.

Installed on a 2006 LBZ. Everything fit just like it should. The aluminum adapter to the radiator is a tight fit if you go in dry, but some lube/grease on the rubber o-ring and some LIGHT taps with a rubber mallet will fix that.Came with 4 large clamps for the main block and radiator hose connections, but not for the smaller 2 connections to the heater hose and coolant bottle. I would also recommend a new spring clip for the aluminum connector to the radiator.Overall, I’m very satisfied. This is not my first Mishimoto product and it will not be my last.

Good quality. Note to stay away from the PPE hoses. Wasted alot if money and after suffering with leaks around the T from the water pump replaced this brand. Only issue is the band clamp was too small at the water pump side.

Got this for a 2007 Chevrolet silverado 2500hd classic 6.6 duramax. Only issue was the coupling being too tight. With a little persuasion from a wooden block, hammer and a little lube, it all worked out at the end.
