I don't see a lot of CSF rads fail, but Koyo definitely has a lower rate. For me to buy a CFS, it's only $5 more for a Koyo.
I have options on vendors for a 1917, and we monitor what is bought nation wide. APDI is not a vendor that we will buy a 1917 from, however they make plenty of parts that are on the money.
CFS is not a bad radiator manufacturer, they're in the upper end of the scale, actually. They make some good stuff. I'm fairly certain the '84 FJ60 has a CSF, a nice 4 row. Seemed like it cooled just fine last weekend, but it only gets driven a mile every 3-4 months.
If the tank on the CSF does fail, someone will be able to work on it. You might get lucky and JB weld could suffice to repair the leak. Radiator shops can remove/replace plastic tanks, it's just a bit of work, time, and you hope the seal doesn't move when it gets crimped back together. JB weld isn't working on a Koyo, unless it's a row that got knicked. When the seal busts, you're done.
It's the same with the Denso, seal goes, it's done. All Koyo, Denso and CSF 1917 radiators are 3 row. There are other vendors that have 1917 radiators, CRS is one, and it might be better than the Koyo even as a 2 row, but I doubt it. 1917 radiator side by side comparison, the Koyo was more robust, and in my humble opinion, better all around.
Inspect the grommets, replace as needed. The CSF is a brick, house.
