Owner reviews for engine radiator

I just installed a nissens. went fine, good fit.

I run the Koyorad 38mm radiator on my NB, with just regular Prestone green concentrate and distilled water 50/50, and OEM Mazda cap and thermostat. Coolant temps stay in the 190's at all times. It very rarely gets above 200 except on the hottest summer days, usually when sitting in traffic.

No issues for years on mine. Turbocharged with a coolant reroute at 250whp. Had their products in my civic and diesel trucks in the past and had no complaints. Going on 10 years with their stuff.

I've had one in my car for a decade of track use with no issue...I've got a new Denso I'm replacing it with when I get a chance since it's 10+ years old now (though its still black and shows no signs of aging really.)

Currently have one in a 97 for about 3 years, I don’t drive the car super hard so there’s no problems at all.

i once put an cheap aftermarket radiator into my audi a4 b5 and it held up pretty good for years. since the car was 25 years old i chose mid priced aftermarket parts and as for radiators i can say the purchase was worth it. i bought a 61€ part from NRF.

Held out for the koyorad and it's the same size as stock and went in with no troubles.

As for highway driving (when the high speed airflow takes over) I saw little to no difference with my OEM vs Mishimoto All-aluminum radiator. Hot day, w/ and w/o AC temps push 220F easily.

I needed to replace the entire radiator in the GTI to get a check engine light to go away.

my Mishimoto leaked/falied apx 10-11 years after I bought it. and keep the receipt, or your lifetime warranty will not be valid
