You don't say if you checked your vehicles viscous fan was fully functioning, so we have to assume you did. There are only three failures the pump can have, a leaking indicated by a drips from the weep hole, a faulty impeller shaft bearing, an a broken impeller which has be mentioned in forum...

The bracket shown is ETC5576 for mounting an alternator on a V8 carburettor engine. My 3.9 has a serpentine belt so in that area there is a power steering pump mounted with a small alloy bracket. https://www.paddockspares.com/etc5576-bracket-alternator.html

🤔 Depends on its size and it’s location, Stillson’s and before starting a splash of Plus gas comes to mind. 😊

Ok that will work, it looks like a D1 wheel which was part number NTC5193PM. As you say the existing spare wheel is alloy so why not replace the vinyl cover? I understand it protects the tyre from sun damage. I’m now on a third cover, original plus two replacements

Correct, those cover discs (ANR4751) were supplied when the D1 was equipped with a steel spare with a size 235 Goodyear tyre fitted. Steel wheel mounting nut is ANR3116 plus a plastic washers. I saw some D1s with a steel spare an a main dealer when I purchased my vehicle … fitted normally a...

The brake pad wear lamp should never be on when the handbrake was applied. It only happened a couple times in the 100,000 miles I did In my 1987 RR, as it should, indicating a brake pad was worn somewhere when the brakes are applied. Early disco had the same electrical system as the early RR so...

Screwed into the thermostat housing just where the housing is bolted to the cylinder head, there are other sensors (a/c) also in the thermostat housing. A replacement for the temp guage is AMR1425. A another temp gauge what ever it displays won’t stop a head gasket failing, cause & effect...

To start with I’d fully charge my battery and disconnect it from the vehicle overnight, then in the morning get a voltage reading, that would tell me which way to go.

No… next question 😊

Only manuals have a flywheel and if its EDC equipped then its an automatic.

Thats correct. EDC was introduced with the 1996MY D1 to give an increase in power in Tdi automatic models

Bargain 😊 Genuine Parts are advertised to be £450 a set. I’m surprised that D1 genuine half shafts are still available.

Just a logical thing the switch is very basic, a maybe again but just tighten the screw it may work. Wiper drive seized is not unknown 😗

This is the diagnostic access for the mfu test I have used and it works perfectly if correctly followed. Close all doors and the tailgate. NOTE: If the oil pressure switch goes open circuit (engine is started) during the following procedure, the MFU will exit the diagnostic mode immediately...

On starting, the wipers would jolt - other than that they won’t run. Don’t know, earth issue maybe The passenger window was opening on start up. After driving it for a while I then couldn’t get it back up. As above The rear fog light switch blinks, when turning from ignition point one to...

I’m sure you know the reason for using twisted pair wire. As you will be using less than 2 metres of cable, normal copper flat twin or fig 8 cable will do. But if you think there could be a issue in you particular vehicle you may wish to use a twisted pair cable then use normal data cable UTP...

I never found the dash illumination an issue and sometimes used the dimming function, also some items have a fibre optic for illumination the for the associated master bulb could be iffy. For genuine illumination there only four bulbs, and white if I remember correctly, also because of the...

The D1 automatic gearbox dipstick has has two markings, max and low and and the fluid level should be checked ‘cold’ with the engine running at idle and after moving the selector from position ‘1’ and back to ‘P’. Depending where you are in the world at an ambient temp 20c.

FTC3908 is the part number for the whole selector kit, it costs more than my D 1 is worth. https://www.johncraddockltd.co.uk/ftc3908-lever.html The early RR may work, its not that dissimilar from the disco, the RR has a buttons on the side of the selector leaver, the disco has a lever underneath.

It’s possible the security system is set and now in an alarm condition, hence th hazard flash, but the alarm sounder/wiring is missing, so no alarm sound. With your disco model the security system is set via micro switches in the drivers door and set the alarm and immobiliser. So u can either...
