Owner reviews for engine radiator

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

Mishimoto oem replacement is cheap dependable and lifetime warranty.

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

I have been running an nrf one for four years now and it's still fine.

Bout to hit 300k tomorrow on my 2012 and I’ll I’ve ever replaced is the radiator and a transmission sensor. All the pulleys are oem

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..

Nissens is ok

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.

I had a 1980 Audi 100 (5000 for the US) and the top of the radiator was plastic. I dropped a socket wrench on the overflow bib and broke it off.
