Hi Folks have just been under the astra (2.2 hatch) to change the fuel filter and noticed my centre section exhaust shield is hanging off. So tried to botch it with some large washers as the bolts were ok. Then managed to shear off 4 of the mounting bolts (and yes before u ask I soaked them in WD etc..) So the heat shield is only held by 2 bolts.
Do I need the heat shield?
Could I get some heat proof flexible sheeting that will stick on instead of the HS?
If I have to re mount a new HS could I just drill into where the bolts were welded with self tappers (or will it come through into the internal floor pan?
Any advice would be welcomed.
