My header tank is rusting so want to replace it. If anyone has one spare or knows somewhere that they can be found cheap :) I would be grateful.

Also, the cover over the top of the alternator and aircon belt/pulleys is looking a bit sad. Options are to repaint or find someone willing to offer me one for a decent price.

Car is an MY98.

Take off the altenator/air con belt cover and polish it. Strip old paint off and get busy with a dremmel, Cheap as chips!
Was gonna do mine but I forgot until now :-)
Might be able to do same with tank?
