Engine Undertray

Engine undertrays were probably only fitted to some diesels in order to increase their working temperatures.

this shows an old, broken undertray alongside a new Peugeot one

Looking up under front of car . . . .

. . . . this is quite likely how yours looks . . . .

. . . . no undertray

This is the new fixing sold on ebay. I couldn't get them to fit tightly in the square hole and they often dropped out if I didn't line the undertray up accurately. The original Peugeot fixing was much superior, though tended to rust out.

so Plan B was to use these 8mm threaded rivet nut inserts

I had to use 8mm ones which is rather overkill, but they fitted the holes well!

steel ones were very tough to fit, but then I got some aluminium ones which squished well into the square holes.

The new undertray was initially secured by these three original Peugeot clips at the front . . . . . . .

. . . . . . . and six 8mm socket-cap bolts.

. . . . . . . and at the rear is located by the cross-brace

The new undertray was initially secured by the three original Peugeot clips at the front and six 8mm socket-cap bolts.

These clips have been replaced by 6mm button-head bolts   . . . .

and the underneath is now protected from stray stones

The new undertray was initially secured by M8 Allen bolts (1) plus springs and flat washers. The button-head screws (2) looked tidier but also needed washers.

Finally, M8 and M6 flanged socket button head bolts (3) not needing washers made a neater finish
