Radiator problem

Recommended Posts

So my Nissan Rogue radiator was leaking yesterday (this Nissan needs repairs seemingly at least once a month...........) at 140k km.

Looks like aluminum(?) tubes, with a plastic tank across the top, and leaking along the tank..


Any thoughts?  I've only ever had old-fashioned rads go bad before and I just take them to the rad shop.  And there certainly isn't many of them anymore!

Yep, every alumn rad with plastic tanks leak eventually. Seems the "crimp " looses its hold onto the plastic caused  the pressure cycles over time. Under the crimp is the plastic tank and between the tank and alumnium core is a rubber gasket. IV taken this type of rad out of the car/vehicle and "re crimped " those crimps and got lucky a few times. Others I couldn't stop so new rad was needed.
