Buick/Olds: 95 Buick Park Ave Belt Tensioner, buick park ave, coolant leaks

Question
Hello Tom,  The belt tensioner on my Park Ave. (non Superch'd) pully bolt threads stripped.  Can I purch a heli coil with a rev thread to fix this.?  There are (2) heater hoses and a plastic pipe) connected to the assembly.  How are they sealed, ( O rings or ? ) I will probably just replace the unit, I just about have it off.  I don't want any coolant leaks when I get it back together.  All suggestions will be appreciated...Pete

Answer
Is it safe to assume that these are 2 seperate questions ?.

Sure you can helicoil the stripped threads, But IF you can, I prefer to drill out to the next larger size and retap the holes.

You stated: There are (2) heater hoses and a plastic pipe)
           connected to the assembly.

Would you please elaborate as 2 heater hoses and a plastic pipe does NOT give me enough information in order to give you an answer.
