I like them, good quality and sure will last a long time.I did re-use the constant tension hose clamps that came factory installed, no reason to go back in time with worm-clamps.Before putting them on I cleaned the barbs at the engine side from accumulated dirt and rust so that the new hoses have a nice smooth surface to seal on.Also I did re-use spring inside the suction hose, it is there for a reason.Last but not least, 2" longer upper hose then the gates one. Fits like the factory one.No leaks, no collapsing hoses, no problems with a little bit of common mechanic sense.

My truck has been overheating due to the age of my radiator hoses and the suction hose collapsing at higher RPMs.When I got these hoses, I immediately saw a problem with how easy to crush they were. I can collapse the suction side hose with lung power. So, I did a side by side with the rubber hoses that have lasted since 2016 and ordered new ones for the pictured test. Not onlt do the rubber hoses ones say *Made in USA" and as you can see the Mishimoto is made in China, but they are so soft. I am sure they have great heat and burst ratings and may last, but if we are not flushing our coolant out in 7 years for an opportunity to fit new hoses then that's an issue IMO.Some lower hoses come with internal springs to keep them from collapsing while others do not require them. The hose that came with the truck had one. You would think they would have made a high quality stainless spring if their hose was going to be this supple. I cannot in good conscience install this hose. Pretty as it is.I am a big fan of mishimoto and their products are all over my truck. All companies have hits and misses and I believe these to be a miss. They are going back.

Great fit and super high quality material. Very happy. If you are serious about keeping your vehicle running tip top, this is good to ensure no leaks! Been running these with a mishimoto radiator and haven’t had any issues. Installed them myself. About 2-3hrs to do radiator and hoses

Description says it fits 2003-2010, but when parts arrived, they were way too big for our 2007. And paperwork said it fit 03/04

Perfect fit, I took the spring from my stock lower hose and put it in the new one since it does not come with one.

They were expensive as all hell and don't even come with clamps. I gave them three stars because they appear to be very well made and look very good. The sylicone appears much stronger and stout than the OE material. For some reason my lower hose started a stubborn leak where it connects to the radiator barb. I have tightened it several times wonder if sylicone is not plyable enough and dosen' t seal like a conventional rubber hose. They are so expensive and unrelyable, definately not worth the cost. A year later and several different clamps later I think I finally stopped the leak. I was wrong, adjusted my rating to one star because there was no lower option. These hoses leak like crazy don't take any long trips you are better off with some Auto Zone or crusty junk yard hoses.
