Hi All I've always been in the camp that prefers not to use stainless in the cooling system on the DeLorean - be that the bottle, the pipe in the "valley" or lately, suggestions of replacing all the pipework on the car with stainless (the original ally ones aren't prone to corrosion!). In researching another project, I came across this very useful page discussing material choices for the cooling system on a different aluminium engine - the science is just as valid on the DeLorean. http://www.rjes.com/html/material_choice.html Best Wishes Martin ------------------------------------ To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnewsYahoo!
