Engine radiator OEM BMW or Nissens

Nissens rads are very good tbh, better than OEM,

I've recently replaced my original oem one with Nissens, no issues so far, works perfectly. it was a super easy install and no issues so far.

I got a Nissens radiator in mine after it had to be replaced last year, and it’s been serving me very very well

The Nissens are inexpensive and mine has been trouble free for ten years.

I put a Nissens in my 1992 325i cabrio and it fit perfectly. It’s been in there for seven years now and all is great. My car was an automatic when I bought the radiator. I later had the car swapped to manual and plugged off the transmission cooler ports on the radiator.

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.

just replaced one and aside from slight issues with the drain plug alignment that needed some finessing, seemed fine and held pressure.

Nissens lasted the longest for me. I was only getting about 2 years out of Behr's.

Don’t use that shitty Nissens radiator. That always leaks, ended up returning mine.

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.
