I brought a Mishimoto Automotive aluminum radiator for my 2006 Dodge Ram 3500 in 2017 from XtremeDiesel. I installed this radiator in the Fall of 2017 and immediately started loosing antifreeze. But I did not know why. There were no puddles under my truck. By 2018, I was having to buy more antifreeze and ad it on a weekly basis.
I finally in 2019 by examining my engine cavity, decided to wrap paper towels around the cap. And every week when I went to get a load of hay it would be wet and the same color as the Mishimoto antifreeze. I started examining the cap and figure out that the tabs that hold the cap down were just flat bent aluminum and were too high to hold the cap closed. So I tapped them down, trying to get them to seal and hold in the fluid. But NOTHING worked as this flat aluminum tab is way to weak to hold it's place, regardless of where you put it. It has "1.3 Barr" on it, but it is NOT even close to that.
The radiator was not leaking, the cap was and it does NOT appear to be individually defective. It appears to just be a Crappy worthless design & manufacturing. There is NO way this cap could have ever worked based on it's design & materials.
So I called them. and they suggest that I tap down these tabs, which I told them I already had. So they told me to go out any buy a radiator cap for a Subaru WRX 2005 model and try that. I asked if they had a cap that would work that they could send me and I was told FLATLY NO. They had nothing to solve this problem. So much for their falsely claimed Warrantee. It's 100% Bullsh*t Lies.
For any warrantee to have any value, it must be honored when it's needed, not just before you start legal action action against a company that has screwed you to help their legal team. This is NOT an open ended agreement that they can do just when ever it please them to. They have to honor their warrantee when they have been informed that their product(s) have FAILED. They did NOT!
I can not drive more than about 75 miles before I loose too much coolant/water to go any further & I'm having to put in about 24 ounces ever time I drive it. I can't even leave my local county. So I went out and bought a 1.3 bar racing radiator cap for a 2005 Subaru WRX for $35 and it would NOT seal the radiator either. I lost more through that cap than the crappy aluminum one.
When I got this high dollar radiator that made all these claims of being 33% better, it was made in China, NOT Japan. The size is 1.37" thick core, which is even less than stock's 1 ⅝", so how can it be 33% better. It is NOT even as good as Stock & never was. And that was using their way "overpriced" antifreeze too. Compared to Evans, it does NOT come close to that level of performance, but cost about 33% MORE (a Yakusa Premium).
IMHO, this apparent Yakusa company is running a SCAM and selling dysfunctional Crap sandwiched between massive amounts of BullSh*t (False) marketing. Be Aware …. don't be scammed by them.
I'm not some young inexperienced kid. I'm highly educated (Magna c*m Laude in Engineering), experienced, mature and do much of my own work on my vehicles, house, computers, etc ....
