Coolant Tank Source

[DarrenD]

I'm just in the process of doing a bunch of work to my 2.5L to prepare for DE track season so I have the engine out of my '99 Boxster. I have the nagging feeling that I should replace my coolant tank. It's not currently leaking but I have no idea if it's ever been done and its definitely discoloured.

I looked into a new one from Porsche and it's $500(cdn) with taxes. That seems rather steep to me. I have one here from Rock Auto but the build quality is terrible, I'd rather leave the old one in.

Keeping in mind that I'm in Canada, Is there another good source for these or is OEM Porsche my only option?

Thanks
