    Oil cooler fittings

    Can anybody tell me what thread size the 2off male fittings are on top of a 3B oil cooler?



    The big ones, not the ones circled. The threads on mine are knackered so I'm looking for a weld on replacement as the brkt is NLA from Audi

    Just for reference the fittings are 12L and they are available from any hydraulic specialist. They are about £4.50 for mild steel or £11.50 in 316 stainless. As the mounting brkt is NLA from Audi I ended up making a new one so I splashed out and had all stainless





    Got a brand new core and seals from VWheritage.

          Nice bit of welding there, if there was such a thing as an "OEM +" stamp of approval surely you'd get a stamp for that handywork.
