How to tell if radiator has been updated on my 2010?

Postby paradigm » Wed May 02, 2018 10:53 am

Is there a part number I can look at on my 2010 pathfinder radiator to determine if the radiator has been updated to prevent the mixing of the transmission fluid with rad fluid.

Or should I do the bypass regardless?

If it's a Nissan radiator, there should be a Calsonic sticker on the very top of the top tank, on the driver's side of the radiator neck. The ones we usually see have a lot of failures are ones that have the 10-digit part number end in -EA215 and -EA265. Keep in mind Nissan never released a list of the problem prone radiators. If there is no Calsonic sticker, there is a likely chance it has been replaced with an aftermarket unit. Personally, I prefer replacing the radiator rather than the bypass as aftermarket replacements can be had for under $100, but bypassing is still better than nothing if you have an original radiator that is potentially prone to failing.

Thanks.

It is a Calsonic radiator, part number 21460-ZL11A. Anyway to tell if this is an updated unit?

That's one of the later part numbers and it is the factory installed radiator. Failures on these are very rare, but I have heard of at least one of that part number that had a cooler failure over the last several years. So, you'd likely be fine with it, but can I say with 100% confidence? Unfortunately, "no." It's really your call.
