Radiator leaking

Quicksilvers · 08-03-2017, 06:06 AM

For the past two days my radiator has been leaking coolant from under my 370Z. After diagnosis I observed that the coolant is leaking from under my radiator there is a very small crack on the bottom of my radiator and I have to replace it. Right now the weather is very hot and humid. I noticed that my 370Z has been running hotter. Is it worth replacing my radiator with aftermarket aluminum two or three core radiator? Will you notice any difference in overall temperature installing an aftermarket radiator versus a Nissan OEM replacement radiator? What aftermarket radiators do you recommend?

On a 2017' model?

A cracked radiator on a 2017 sounds like a warranty issue to me.

First thing you need to do is check coolant level - if it's leaking in the driveway, it's leaking going down the road. Top off as needed.

Then take it to a dealer to see about getting it replaced under warranty (see Chuck33079's comment above). While getting the repairs made, you can take your time looking for a better radiator.

This is a 2017 370Z and I checked the fluid level and it seems to be a bit low. There is a crack in the stock Nissan radiator according to the Nissan technician. This radiator is covered under the powertrain warranty according to the service advisor at Nissan. Thanks for the advice. I will look into replacing the stock Nissan replacement radiator with a upgraded aluminum radiator if this 370Z runs any warmer than it does now. I am thankful that my 370Z did not overheat with a faulty leaking radiator in this hot and humid weather we are having.
