I got all my bits together to do a oil change but on
trying to unscrew the undertray to access the oil
filter the screws that hold it on are stuck solid.

I have snapped two screwdrivers trying to free
the screws, any ideas for easing them?

I have sprayed the screw heads with wd40 from below
and will try again tomorrow but all ideas welcome.

 

i found it best to drive the front of the car over the curb then you have better access, more pull, unless you are on axel stands

 

my old 206 but you can get the idea what i mean

 

It's on stands, arms aching from turning and breaking
the screwdrivers

 

oh, im suprised there not hex bolts on the classic,

 

Ah ****, never thought of that. Kinda awkward to see
and thought they were cross head screws, will try a socket
set.

That's got it, 12mm socket should do the job. Gonna tackle
it tomorrow and will update.

Cheers Dan

 

i think its a 12mm but its been awhile since i fiddled :P

 

Ah well only the two screwdrivers in the bin.

You live and learn eh

 

glad i could help you

 

omce the bolts are out id run a tap through to clean out the threads , and copperslip the bolts on replacement , good luck

 

All sorted now, happy days. Copper greased the nuts
aswell so they come off a little easier next time.
