Leaking Radiator Neck

[aamarakoon]

There is a small leak from the neck of the radiator where it joins the upper tank. Leaks only when hot. Not a drop leaks when the engine is cold. ( model - 2001 sylphy) Radiator cap new. Both fans working properly.

1. Is it possible to stop the leak using a glue or an epoxy?

2. If,so whats the best product?

3. Or, do I need a new radiator?

Thanks in advance!

I too had a similar issue and it turned out to be a cracked top tank, it was only leaking when the engine was hot. Had to replace the top tank since the crack was a little too big to fix with glue. Total damage around Rs 6000

Take the car to a garage and ask the mechanic to inspect.

You might need to replace your header. Top tank I mean. Get it done in copper (or brass?) newer cars have it in plastic and tends to crack very early. There's a radiator guy on Stratford avenue opposite gandhara. He's good

Replaced the top tank of my lancer a few months back with a plastic one. Went to radiator house nawinna. Cost - 7000, they cleaned the radiator as well, the job took < 1 hour.

Hi,

Commonly speaking, if it is a copper one, most probebly can be able to repair but it has to be done by a good mechanic (specilized on copper welding and radiators) I think becouse it gets hot and is a part that need to handle with care. If it is a plastic one, the best thing is to replace as I see. But when you do the repair, it is possible to get the radiator cleaned with both tanks and checking the horses as well.
