Hello Everyone,
Since my last post about getting the engine bled I have been accumulating some more spare parts including a used exhaust manifold. I got this used manifold it had no expansion plugs in it (I would call them freeze plugs but Volvo seems to call the expansion plugs). I managed to get what I think are the right expansion plugs (35 mm) and advertised as right for MD11C. The expansion plugs are circular and concave or convex (depending on which side you look at them). It looks like you could put them into the manifold either way (so from the outside of the manifold you would be looking at the convex side or the concave side once installed). My questions are:
which side should be facing outward when into the manifold convex or concave?
Does it matter which side is facing out?
How do I install them?
Looks like you just tap them in with a hammer or something
Do I use some kind of sealant on them when I install them to prevent leakage from them?
I have the plugs and have cleaned out the manifold with a mixture of water and muriatic acid (neutralized afterward with baking soda and water) and am ready to install the plugs but not sure how to proceed. Thanks in advace Carole in FL
