Title: Maintenance Guide Index
Post by Jimbob on 23. Nov 2009 at 19:16
Read before following any guides

Obviously safety is paramount. These guides are all written by members who have done the jobs themselves, none of whom are professional technical authors. Therfore, they are to be read on the merit of items that will assist you rather than a precise 'follow this to the letter' type guide.

Whilst every care is taken to ensure the accuracy of these guides, you should satisfy yourself that they are applicable to your vehicle, you have the necessary skills to carry out the task and that you follow the usual safety procedures associated with working on any car. That is, you secure the vehicle using brakes, chocks and wedges where necessary and that you NEVER work on an car supported only by jacks. Always use axle stands positioned appropriately.

If you have any doubts regarding safety, ask BEFORE you attempt any job on your vehicle.

None of these guides are endorsed by the owners or administrators of this forum. You follow any of these guides at your own risk

Submitting Guides

This section is by no means complete.

There is always room for new, or improved guides (just because we have a guide, it does not mean it is the best way to do a job, if you know a better way, please create a guide, likewise if you feel a guide is 'missing' feel free to create one).

If you would like to add to this section, please create your guide in the test section, from there we can copy it across, add to the index, and add some copy protection to any photos.  You can either add photos using photobucket etc, or you can email them to the address in my signature.  Photos will be moved onto the OOF servers.

If we see what we consider to be useful posts, we may request you make them into a how to, obviously there is no pressure to do this.

Thanks to all our contributors, past, present and future  :y
