Engine radiator OEM BMW or Denso

Replaced with original.

24 years is good for me.

The stock piece lasts well over a decade in my experience. That's more than enough for me for a part that fits and functions perfectly.

i used a denso radiator on a benz gle43. Worked out pretty well. I mean they are an oem supplier for many manufacturers.

Denso and other OEM for me. When insurance wanted to throw Napa parts at my radiator replacement destroyed by a napping squirrel in the fan assy, I ponied up the difference to go with the Denso and mechanic confirmed it was a solid choice.

Aisin water pump, Mitsuboshi or Bando belts, and replace the radiator as a preventative measure with a Denso unit.

I replaced mine at 129k miles due to a small leak in the bottom of the radiator. I purchased an OEM Denso one on Amazon for 220 and it's been working great, no issues with trans temp as well.

OEM radiator. Replaced radiator on visit 5 (today). Bmw closed loop network is what eventually led to the radiator being checked as they’ve seen aftermarket radiators actually cool the cars too much, therefore sending the tstat fault in cold weather (this issue occurred first last winter for me, then again 5 times this winter.. all same fault code). Confidence that this is the root cause fix seems to be high so fingers crossed I won’t be updating this in a few days.

I recently did a timing belt job on my is300 and now the car feels weird. I replaced oe denso radiator. The first startup was very rough. After some tinkering with the car by letting it idle for a while, reving it slightly, the car seems to be alright with no check engine light or any missfire codes. However I do feel like the engine vibrates just ever so slightly more than it used to. A barely noticeable difference but I feel like something is not right. The car now also has weird cold starts. The engine only revs up to a 1000rpm and then goes down from there, where it usually would rev up to 1500-1800rpm on cold starts.

The MVP radiator and the Denso aftermarket are identical, both say Denso. The main difference between the OEM and the MVP/Denso is the OEM is 2 Core with a radiator thickness of 1.075 inches thick. The Denso is 1 Core with a radiator thickness of 0.663 inches thick. I measured the thickness using a digital caliper. Another difference is the transmission connection lines, the MVP/Denso looks like a cheaper aluminum, and the OEM is a heftier non aluminum metal. As a side note, after searching the internet and YouTube, some people have leaks at the radiator line after a couple of years with the Denso aftermarket ones. Next time I will be sticking with the OEM model, I just don’t have time to return the Denso and order another OEM one.

I've replaced a radiator on a BMW 2018 3 Series with as little as 22k miles. This particular vehicle was leaking from the side tank of the rad, where the plastic is crimped to the aluminum. Nothing abnormal could be seen, just the crimp failed.
