Wedged the GTI's radiator in. I was pretty worried about the Nissen OE equivalent I bought on FCP euro being enough for the VR6.
i am dealing with radiator business in Turkey, and all i can say is Nissens is good brand. And fins will be okay, i cant see any major damage, but need to make sure check for the leak.
That’s exactly where my OEM radiator started leaking, luckily it was very visible, I strongly recommend changing the radiator, I got Nissens and it’s been working great so far it came highly recommended by my mechanic
I put a nissens radiator off Amazon in mine 3 years and 80,000 kilometers ago and its held up. Multiple cross country trips with it.
Nissen OEM style replacement is good
I installed an aftermarket Nissens rad and the operating temperature dropped by 2⁰C, also great fitment and price wasn't too bad either
2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.
It happened to me once at a night time. I just pulled over, stopped the engine and started again after several minutes and everything was OK.
Edit: After reading other's comments, I realized that mine also related to coolant system. Some time after this incident I replaced radiator because of a coolant leak. May be this warning is related to that.
My first non warranty repair on my B58 540 was a $3k radiator replacement. That was at about 60k miles.
The ~2014 Nissens, with the 15 round tube design just doesn't cut it. From what I can tell the car would've come with the 30 flat tube design. The Nissens just doesn't have enough surface area. On a hot day, with the AC going and highway speeds it just couldn't keep up.
