What spare parts do I need on the trail (D90)?

[revor]

Aside from what has already been mentioned here, there is a goofy plastic plug for the radiator that you may want a spare. I actually don't know if the D90 uses it, but the Range Rover of the same vintage does. This is not the cap for the expansion tank, this is actually in the brass of the radiator. It is easy to damage if you remove and replace it. Brass caps are available for the radiator, too.

I always carried one, thereby ensuring I would never need it.

Buy a Stainless of Brass 1/2" NPT pipe plug to replace the plastic plugs, Or 1/2" British straight pipe thread if you can find it.. The 1/2 taper piep works fine.

Bring some fluids and don't worry about the rest.. Replace the Oil Cooler lines.

They're really reliable.

On a Gems engine if the Crankshaft sensor or the cam shaft sensor fail, there is no spark to the engine the engine will not run, you will be limping home on the end of a tow rope. The Gems system will go into default mode with the TPS,(limiting to around 2500rpm- unless it fails in the closed possition when the engine may not run at all) The MAFS will also "go into default mode" but with limited performance -spare is affordable and worth carrying. The factory workshop manual or RAVE gives a usefull overview/explanation of how the various sensors work/ default /limp home mode etc. Again info only applies to GEMS engine.

Your the first person I have run into that carries them. No Defender owners in the CLRC nor most folks on D-90.com carry them. Hell, most Disco owners I know with years of experience don't carry them either. Unless your using cheap parts, failure of the sensors doesn't appear to be common place. Most folks on D-90 post up at around the end of the useful life, but I have yet to see a post where one failed out of the blue. All of mine are original and still work perfectly. I'm only at 40k on the clock.

Unless I am going 3+ weeks out west in the middle of nowhere, I wouldn't bother with them. Most people wouldn't be able to properly diagnose the problem without a code reader anyway...

God I gotta call that buyer and get this POS coiler out of my Garage so I can get to the leafer promised land...
