so my 5th gen cali SE is leaking coolant.
mechanic hooked up a hand pump pressure thingy and it's leaking from a corner of the plastic tubing that runs across the top of the radiator, just under the air intake scoop.
my question is this, will jb weld work??? does it even adhere to plastic and if so how would i perform with pressure?

i'm sure i'm not the first one to leak coolant.

any help or ideas is appreciated.

thanks.

 

Just replace the radiator.

JB weld or quick steel will help slow the leak allot but isnt a permanent fix, I used some on mine when i had to wait for my koyo to get shipped. Also more leaks will start to show up on your radiator, i noticed after i sealed up the leak on mine i noticed where coolant was starting leaking in a few other spots.

 

Ok I just found out I have a very similar problem. Now where did you buy your radiator and how much is install

 

Man I've noticed the cooling system is the worst in the Maxima. I've replaced thermostat, both radiator hoses, and BOTH freakin fans to fix an overheating problem I had a year ago. Now it seems like the radiator.

 

+2 on replacing the radiator.
Delaying that may cause overheating issues which will lead to co$$$tly engine damage (taken straight from my experience on a Camry I used to have years ago).
