After my third one I called it quits. Purchased an OEM on car-part.com and had Nissan in Gainesville, Florida install it for me. No more worries. Aluminum radiator is pretty unnecessary in my opinion, unless you're seriously tracking the Z. Investing in an oil cooler would be a much more appropriate expenditure of funds.

I'd go CSF after my recent debacle with Mishimoto.

I canceled an order via email 5 days before it shipped. Ten minutes after I received the shipping email I called and asked why it shipped if I canceled 5 days previous. I was told they haven't read their email from 5+ days back. I asked what good is having an email account then. I was then told if the shipping department couldn't catch the box before it left the building with the transit company I'd be charged a 10% restock fee. I argued that its no fault of my own that they don't check their email and their response was that's our policy. Of course my final words were that's **** customer service. Called my CC company next and disputed the entire charge.

After this experience I call BS on their whole, "we'll replace if you're in an accident claim."

So there ya go outed over $4, hope they're happy.

I can sing this song all day. CSF = junk

The pics I posted on page 12 says it all. CSF = junk everything as far as I am concerned.

I think I am going to get one of these. I know better than to not get something. I have been down this rabbit hole before. As soon as I get stuck in stop and go traffic in the South Georgia heat the temps will climb and may not stop. It will drive me crazy if I don't do something. I will just classify this as a maintenance cost of going boosted and it will need to replaced every 2 years. Labor will be free. I just don't want to cut holes in my car.

Super old thread, but I remember reading this prior to purchasing a CSF from Z1 back at the end of 2019 so figured I'd provide an update.

I purchased mine in August 2019 and it failed in the same location discussed on here. It was a class 1 leak for maybe three or four weeks. Fluid levels looked fine, but I could smell the coolant and saw the buildup where the fins meet the tank when I inspected it. Today it turned into a class 3 and was losing a little more fluid than I was comfortable with.

It lasted just over 4 years and 23k miles. NA I would see average coolant temps around 220f during the summer in AZ. I put the CSF radiator in at the same time I did the SC, and I don't think I've seen it above 204f during normal operating conditions. Maybe I'm retarded, but I ordered another one despite what I'd consider a short lifespan due to the temp difference.

Mine is still going strong for now. If it has an issue, I will get another one same as you. It's a maintenance item. Now is the time to buy due to Black Friday sales next week.

Saw someone on Facebook who got a shop (or themselves) to attach an OEM condenser to the Koyo radiator.

I swapped from OEM to Koyo this year and it's done well keeping up with my Rotrex SC'd car on track, which has a large intercooler and a short but full width oil cooler in front of the radiator now.

I'm glad you mentioned the condenser! One of the things I forgot to put in my post is they apparently changed from the stock detachable A/C lines to fixed. Kind of annoying for me because I converted the OEM to soft lines because the hard lines won't fit with the intake there.
