My 91 has developed a leak from the plastic radiator head tank.

The leak is right on the top in the center of the radiator.
There appears to be a flat spot where a label would have been placed. The leak is from a slight crack on the bottom of the flat spot.

I have tried two methods of sealing the plastic tank. neither has been successful. first was a plastic plumbing pipe of the proper diameter, cut in half, glued with multi purpose plumbing cement. It did not hold. the second attempt was fiberglass - done twice -both have eventually failed.

Question- what will stick to this plastic tank.

the location of the crack is left of the coolant sensor.

Thanks,

Hate to be the bearer of bad news, but its new radiator time...

that plastic has gotten brittle, and will soon pretty much disintegrate...

I had the same crack.
I used a dremmel cut-off wheel to open the crack and patched it with Bondo Marine Epoxy putty stick.
The patch held, but another crack opened at the crimp connection to the core about 3 months later.
