End of life no parts anymore

Failing that, just cut off the current cooler pipes somewhere convenient, swage the ends and bridge with rubber oil hose and a couple of jubilee clips.

This^ I'm sure the oil will never get too high without towing. Use good oil too. And get an oil temperature gauge if you're that worried about it

Dissimilar metal corrosion would be one reason

Copper doesn't corrode though? 

It oxidises in air, but I can't see an issue with copper pipe with oil on the inside and coolant on the outside? 

It's not like it's got to last decades or anything like that either.

It's a long way down the galvanic scale from aluminium, but then again, so is the stainless steel that the original cooler is made from.

It'll be the aluminium that corrodes, hence the importance of coolant changes.

It's all good saying that but who will make one,

No idea 


A more cost effective alternative would be to find one of similar dimensions and modify the bracketry so that it fits in place of the original.

These folks will even sell you some shiny new hoses to connect it to the block.

This no use?

I don't see the dreaded "out of stock" tag so might be worth a shout, although it might be contact for enquiry only as I don't see a buy button.

theres always a few breakers about. either on here on on ebay the engines were well used in various cars including saabs
.a second hand  cooler should be fine if the cost of new is putting you off..after all every omega is fitted with one !   in fact every used car  out there is a collection of used parts bolted together !
or as mentioned a replacement could be fabricated (or bypassed)
nothing to make me think the car should be scrapped especially if its a good example otherwise.

Weren't post facelifts stainless steel anyway, and I guess anything in any other vx/saab of that era the same?
