Hi Guys.

About 10mm crack on the neck (brass) of header tank.
Any chance to fix it by using some glue such as epoxy etc. or welding is my only option ?

Thank You

 

The amount of pressure and temp id say weld is the only realy safe option, epoxy etc have a max temp usually of like 100, i wouldnt want to risk a leak really with epoxy

 

it may be ok as a quick fix but as the system is under pressure its not ideal and may fail at any time.
a second hand header tank isnt very expensive and surely the best option

 

Thanks guys.
I knew that welding is the best bet but had I little hope that there is...
Never mind, will take it off and find a place that could repair it for me locally.

Ps. This is my new (second hand) header tank I've just bought :-(
Didn't check properly on collection and discovered this while fitting. Seller said that will refund me the amount spent on repair.
How un lucky was this ??!!
Needed a header tank ASAP to have a car running on Monday, travelled 35 miles each way and finally have no use from it because of this...
AAAARRRGGGGHHHH !!!!

 

Send it back to seller for full refund and get another one. That is what I would do.

 

I can't really :-(
I need the car today so if I'll send it back, that would take at least 2 days.

 

Braising would be the only and best option , bit of good luck getting a refund though, lesson learnt i suppose check thoroughly before buying.

 

+1 .I would Braise it or replace it

 

Just had the same problem and ended up putting a new top on the tank.

 

Id fit an alloy one from a newage car.
You can pick them up cheap second hand and they wont split

 

Sorted :-)
My local Radiator company fit the new top saying that crack was too big to be welded/soldered. It cost me £30 which I've informed the seller about. He replied saying that's OK and give me a call tomorrow due to being busy ATM. We will see. Hopefully I'll get £30 back.
