Been thinking about getting the Koyo radiator and was wondering if there are any major issues I need to be concerned about. Car is stock and I know about the radiator cap. I did the search and am doing it mainly doing it for the styling (looks) of the Koyo.

Thanks

 

done and no issues.

water temps are lower which is great on the track.

 

been using a large koyo aluminum rad on my GSR integra for years now, coolant temps are def lower and its worth the money!!

 

Works great! Cheap, reduces temp drastically. OEM ish fit, better quality. Only problem I have is my J's rad cap came apart. acn't blame the rad though.

 

hear its bad if you don't need a reason for it because everything takes longer to get up to temp, besides that its suppose to be bulletproof

 

Had mine for 5 years I think and still works like it should. No complaints.

 

Patience my friend

 

that doesn't make it bad, you just need to cruise for a little longer. it's nothing drastic though...i have the koyo too, and the j's thermostat and fan switch took MUCH longer to warm up.

had to remove them though cause the car would never break 2 bars unless i was sitting in traffic. on the freeway i was running at about 158 deg...too cold.

with the koyo only it's about perfect. freeway, 80 mph it's about 174

 

was it the correct J's cap? there's one for oem radiators and one for aftermarket.

i have a cusco aftermarket rad. cap on mine. no problems at all.

it doesn't do a thing....but no problems at all

 

It's the Koyo specific cap. I had the stock style J's cap when I had a stock rad.
