The header tank in my sapphire cosworth looks the same as the ones in a 3dr and because of that they appear to be commanding comical prices on teabay... My mechanic has suggested replacing it as it has hairline cracks in (even though it still works fine just now).

What are my options? I can get a new one for a 4x4, can it be made to fit? What exactly is the difference? I don't want an aftermarket looking item if possible as the car is standard.

 

IIRC you will just need to change the top hose which is larger diameter than 2wds at the header tank end of the hose if you go down the 4x4 tank route.

 

Use a 4x4 one and buy the convertor hose from Roose in black and it will all look original, easy job.

 

Cheers for advice, I'll get a new one ordered
