    Anybody know what size hose this is: part# 42? I don't remember seeing one this small listed for the coolant system when I replaced most of the hoses 2 years ago.

    If you can't find 10mm metric hose (I can't seem to locate any local places that sell metric hose), either 3/8" or 7/16" would probably work. If you go with 3/8, and it is tight, try the old soap and water trick, or heat the end of the hose with a blow dryer and it should fit on.

    3/8 fits fine. Get a good look at the nipple on the crossover pipe where it attaches. By now most of them are pretty eaten up by corrosion.

    Thanks guys. I'll be sure and check the cross over pipe too, Brian. Thanks for the tip.
