Engine radiator Koyo or Nissens

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.

Koyo for top quality, mishimoto for normal quality. Both will do the job well

I just bought a Koyo, goes in tomorrow and appears to be great quality

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

Seems like a loose ground, my s13 did this when the grounds randomly came loose. That said my s13 cluster is so damn slow to react so I run an aftermarket gauge. I have a koyo rad which came with a slot for an aftermarket sensor.

Also i would hope it's not the case, however you mentioned this after an alternator change. I had a 96 civic with a turbo setup and I had an alternator with a failed voltage regulator, all of my aftermarket gauges and temp gauge was acting like this. I would check the volts from the alternator if this is the case, it also ballooned the hell out of my battery..

If you can\u2019t afford the OE Modine radiator, get a Nissens one from FCPEURO with BMW hoses (NOT Rein which are absolute junk). Stay far away from Mahle radiators which are also junk and not worth your time.

my car's radiator is $200 for an underperforming Nissens radiator.
