For those with 5th and 5.5s, how many of you guys installed a Koyo rad? Are they still going strong and staying sealed after many years?

Mine is almost 2 years old, and not sure if it's normal, but I see a tiny bit of white powder (caked coolant) on a small portion of the top housing where you could see the toothed metal. Just noticed it today as I was going to renew the engine coolant and had my Lisle spill-free funnel kit ready for service.

I'm curious if this seemingly-mild seepage is normal. If not, maybe I'll hold off on the coolant service and wait for it to get worse before replacing again.

Thanks!

I put a Koyo in my 97 in Feb of 2009. No seepage.
I put a Koyo in my 2000 in March 2011. No seepage.

Maxima 97 SE

I put a Koyorad on my 97 maxima as well and no problems and it runs strong and its the same exact design as the oem nissan radiator.

I installed a koyorad on my 4th gen 1996. Two years, no problems. It looked like it was a quality product. The 5th gen radiator would not be much different.

some parts that hold coolant seep like that resulting in powdery dried up stuff, thermostat housings etc can do that. unless you see wet coolant at the seams, i wouldnt worry about the powder

if the powder is still bugging you, seeing as its an all-metal radiator you can put JB weld on the seam where the powder is. maybe 4-5 thin coats, i ended up doing that on my Supra on a few spots that seeped coolant and that fixed it
