Hey Mohamed, I am not sure, if this is what you want, but you can import different PEG molecules from coot's "File-> Get monomer". A list of different length PEGs three letter codes can be found on page 1278 of this paper:
Naschberger et al., (2016) http://doi.org/10.1107/S205979831601723X. I think you must have ccp4 installed, for this to work, but I am not 100% sure.
