i am  replacing my 1987 thermostat housing. does any know what size bolts
holds it  on to the engine. is it allen,torx or triple square??? also if there
any tips  in replacing this?

Patrick,  those bolts may be hard to remove.  They are allen head.  Insert an
 allen head socket key with a long extension and then bang on it hard with a
heavy hammer to try to loosen the threads and corrosion around the shaft of
the  bolt before trying to turn it out.  Going slowly left & right may be of
some help to loosen them also.  If you get them out, replace them with
stainless steel ones.  I have them or you can find them locally.  From  my _Vanagon
