It connects to a switch on the clutch pedal to shut off the cruise control on a manual gearbox version.

Spare wheel well filling up is usually tailgate seal or rainwater getting in around the rear light seals. About the only place water can get inside the lower tailgate would also be around the rear light seals for the additional light clusters on the tailgate. Maybe someone has taken the lights off in the past and put them back without the seals?

I assume it's the same on a Disco but on a P38 you can take the rear door off and cut through the loop that the latch striker hooks around. Someone made up a tool for doing it using a steel tube with the end of it shaped to fit over the loop then use a drill down the centre of the tube. That stops it slipping off while trying to get the drill started.

is it the relay or the socket? The terminal for the input from the engine ECU went intermittent on my old fusebox so as a work around I poked a wire in the hole and jumpered it to an ignition switched supply until I replaced the fusebox. The old one had already been pulled apart and repaired not long after I got the car so figured it deserved a brand new one. I normally use these https://www.autoelectricsupplies.co.uk/product/169/category/36 and get the ones with the diode. Rated at 40A so better than OE which are only 30A. For replacements for the 5 pin changeover ones, these https://www.autoelectricsupplies.co.uk/product/174/category/36.

But I cruise at 75-80, even with a trailer!! Did you wind it up to the red line?

Agree totally. Mine seems to get smoother and more powerful after the first 30-40 miles so they do need a good thrashing every so often. Seen 105 on the sat nav on mine (showing 106 on the calibrated speedo) once on a long gentle downhill in Germany. Decided it probably wasn't such a good idea and backed off as I had a trailer on the back loaded with two keyboards and a 12 piece drumkit......

Whether there is any truth in it I've no idea (although it could adjust the adaptive values for WOT) but you've got a Sport button, so use it. Always entertaining to poke the button, floor the throttle and watch the tacho run up to 5.5k before the gearbox changes up. Makes you wonder how something with the aerodynamics of a small bungalow can accelerate that fast......

That makes perfect sense. As you say, even though the engine had stopped firing it was still connected and the pump and torque converter was still turning. So my thinking was right, if the engine isn't turning the pump won't be so there's no drive so it isn't possible to tow start an auto, no matter how fast it is moving. I'll carry on keeping a spare starter motor in the boot when I disappear off to the Continent......

So you can tow start an auto if you go fast enough? My understanding was that as the pump isn't turning there's no drive from gearbox output to input.

There's pressurising and over pressurising. When the engine gets hot the coolant expands so the system pressurises. When it cools down again, the pressure is gone. However, if combustion pressure is getting into the cooling system, it will pressurise when hot and remain so when it cools downs. That's your easy check, remove the coolant header tank cap and put it back on to ensure there is no residual pressure in there, squeeze the top hose to confirm no pressure, run it to normal temperature, squeeze the top hose to confirm it is pressurised, switch off and leave the car overnight. By morning, the top hose should be as it was before you started the engine.

If it still has pressure in it, you are getting pressurisation so take the spark plugs out and look at them. If any are cleaner than the others, they are being steam cleaned by coolant. If it is any of the end cylinders (numbers 1, 2, 7 and 8), it is head gasket, if any of the middle ones, it is leaking around a liner. In which case, the stuff you linked to will cure it. However, the active ingredient in Steel Seal is Sodium Silicate, also known as Water Glass and it's much cheaper to buy it without the pretty green dye https://www.ebay.co.uk/itm/Sodium-silicate-Water-Glass-500-ml-Free-Post-in-UK/264718636840

Airtex, Airtex or Airtex, that's the only pump to fit. I wouldn't fit anything from Britpart that critical.

Unless it's new, I would say water pump, but there are a couple of bolts that go through the water jacket and people have suggested coating them with RTV when putting them in.

That's how you should do it although when I've tried to post from Google Drive in the past it didn't work. Most now upload the pictures to Imgur.com and copy and paste the Direct Link from there.

They are for me. Just checked, they are Google photos, maybe they are location limited? Paul posted the same result and pictures on the dark side, maybe pictures from there will work for you https://www.rangerovers.net/threads/heater-core-temperature-sensor.57289/#post-2322902

No, it just goes a bit rubbery. Anyway, if your heater matrix inlet got up to 100C you've got more things to worry about.

I keep around 1/4 tank full in mine all the time. No danger of burning out the petrol pump by running it dry and enough to be able to use it in an emergency to get me to the next LPG station. Admittedly, I've worn out the track on the level sender around the 1/4 full mark so it sometimes reads nothing at all. Waiting for a slightly warmer day with no rain to fit the new pump I bought pre-lockdown.

For some perverse reason it always amuses me seeing the sign that says Wankum Ausfahrt. It also tells me that I'm almost into Holland.......

Yeah, it's mostly links to porn sites and garbage in Russian, predominately being posted in the early hours. So when I refresh my connection while drinking my first coffee of the day I see them and kill them then. The site does have a blocker to prevent someone registering without a valid email address and a couple of other hoops for them to jump through, but still some of them get through. If you look at the memberlist, you'll see an awful lot of registered members that have never posted anything. Some may be genuine and they are just a bit shy, but the ones with user names that don't seem like something a normal person would use, are invariably spammers that haven't posted anything yet. Gordon has a bit of a clearout every so often and deletes a few too.

Nothing comes up searching eBay for those numbers. Thought it might be because I'm using eBay.co.uk but tried .com and got the same. Full link might be good.

??? A P38 doesn't have a rear anti-roll bar. Unless it was an accessory maybe. I know you could get one for the Disco 1, but never seen one on a P38.
