Good afternoon gents!
I need a pair of expansion tanks, does anybody know where i can get them from?
The need.....

pressure cap, because the rads dont have them
1x15mm ish drain at the bottom,
3x8mm ish pipes on the side, 2 near the the top, and 1 near the bottom

Looked on ebay theres nothing which suits

They will both be mounted next to each other so need to be symmetrical really

have you tried alloy fabrications?

give james a call at alloy racing fabs he would make you a pair tell him i told you to call him cheers paul

2 mounted next to each other? interesting
yep Jim at alloy racing fabrications is your man

Unless you have two engines with separate rads only use 1 tank 1 pressure cap or you will get airlocks, normal plumbing is:

Air bleed from cylinder head(s) and top of rad T'eed together in to the top expansion tank.

Return from bottom of header tank to bottom hose or bottom of radiator.

thanks guys, the second rad is for a charge cooler setup, 1 rad & header for engine

I have one that fits your description, came off a shiny newish (bent) Corsa in the scrappy.
