Do It Yourself (DIY) Guidepost


I would like to take a fresh look at reorganizing the Do-It-Yourself threads here, by:
1) finding/identifying the best ones
2) providing a dedicated thread for nominations of newer/better ones
3) adding rudimentary keyword tags above each link (which may not be in the title)

If you know about a post that is superior/complementary to one already listed, or if you know about a new one, please post here with:
- the link
- some keywords for reference

Better yet, if you are motivated to create a better-written / more-accurate version of a DIY here, please do so, and let this thread know about it.

Gustav has added a "DIY" prefix which you can apply at the time you post your new DIY thread.

Thanks for the help.

When to do it?

Note: The following intervals are meant only as very general guidelines, and may not be suitable for your car or your driving style.

Again, I’m seeding this with information I have cataloged for my own purposes, based on observations made about when owners addressed them. That starting point may or may not be correct. Please post replies with errors and additions.

Air filter – every 15k miles / 25k km
Brake fluid – every 2 years, or less
Coolant – every 3 years, or less

Think about at 50k miles / 80k km, if not already done:
Transmission fluid
Pre-cat oxygen sensors

Think about at 70k miles / 110k km, if not already done:
Fuel filter
Thrust arm bushings
Power steering fluid
Wheel bearings

Think about at 90k miles / 145k km, if not already done:
Fan clutch, radiator
Fuel pump

Think about at 100k miles / 160k km, if not already done:
Rod bearings

Absolutely, many thanks for this. I reckon a lot of members on here hold the DIY's in very high regard and they are extremely useful, they must be saving us £1k's in labour costs.

Great idea to sort them out a bit.

2001 E39 M5 : Silverstone Blue, 19" Breyton Spirits (horribly rashed...Genuine BBS LM's to go on), Philips Silverline Indicator Bulbs, Intravee II and Alpine KCA-420i (in a box in the house) and 160GB iPod Classic , Evolve headers and race cats to go on, otherwise standard at the mo...

"I look at it like this. Owning an M5 is kind of like dating a slamming hot big-t...ed blonde, who is a pain in the *****, drains your cash, but screws like there's no tomorrow. Owning a Honda Civic or the like, is akin to dating a girl who is fat, ugly, smells a bit where she shouldn't, is a cheap date and doesn't screw at all (you don't mind). So yeah, I'll take the blonde." (Courtsey of Jetpilot718)

The thread of my car and it's progression to mechanical perfection... : if I ever get around to anything...

Cabin Filters 6/3/11, Bosch wipers 21/5/11, OEM air filters 24/5/11 (110,920), Oil Change, Oil Seperators and Thermostat 07/08/11 (112,699), Final Stage Resistor, Coolant Temp Sensor, Silvered Indicator Bulbs 21/08/11 (114,110), Private Plate 23/10/11, Came home from storage 13/02/13
