Engine radiator Nissens or KOYORAD

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 was recommended Nissens as a OEM quality radiator replacement. No issues so far in 30K miles with lots and lots of hard driving, drifting and 1 track training day on top of dailying it come rain or shine.

Bought a Nissens like I should have in the first place and all was well.

im steady at 75°C (167°F) with stock Ka, koyorad radiator, fanshroud and oe/oestyled clutch fan. and iirc, a stock nissan thermostat. hottest ive seen was like 89°C (192°F) and that was sitting in traffic on a hot summer day. idk how im running so cold lol.

I went with the Koyorad on mine. Everything fit perfectly, no modifications needed, which hasn't always been the case for me

I am running a nissen radiator, no issues 4 years in.

Ive had my car enter limp mode multiple times on a high 80 track days. Coolant temp would spike to the 3/4 marks. When I upgraded the radiator to a koyorad I never had issues again.

I got the thicker Koyorad and managed to get it to fit with some redneck engineering, but it was a squeeze.

I bought a Nissens radiator because it was the highest rated one for my car. Everything went so smooth initially. Bled the system, pressure tested it, drove it for 20 minutes, and it ran beautifully. Checked for leaks, nothing. Then, the moment I drive off the lot, my low coolant light comes on and coolant was pouring out the bottom of the car. I got a (2E83) *Electric coolant pump, reduced power operation* error. The car never overheated or went into limp mode.
