  1. Which wire in the roof lining of your 400x did you need to connect to? Was the connection to the battery to provide 12v supply to the caravan for charging leisure battery, etc?
  2. I have just invented a new service schedule for coolant change. The easy method: Instead of changing ALL of the coolant every 5 years, drain the radiator and change ONE THIRD of the coolant every 18 months. (I expect somebody will be along in a minute to tell me about a problem with this method....)
  3. It all looks so easy on the workshop manual: two nice little plugs protruding from the front side of the block. What they don't tell you is what else needs to be removed in order to see these taps / plugs. I can't see anything remotely like those shown in the diagram. What I have spotted is a round metal cover close to the oil filter - slightly higher and to one side - held on with two nuts. What is behind this cover - it does not look in the right place to be related to these drain plugs.
  4. OK Herbie. I've now determined that 3.6l drained, and I'm now in the process of refilling with the old coolant to ensure that it really was full (to save wastage of new coolant). Initially, I couldn't find the relevant section in the workshop manual, but I now have, so no need for you to look it up. There are two drains on the block, apparently.
  5. I noticed that the service schedule for coolant change is 10 years initially, then every 5 years. I was wondering why new coolant does not last as long as that put in when the car is new. Perhaps this is because at coolant change, the change does not actually change all of the coolant - and some (half?) of the old coolant remains?
  6. My drive has a slight gradient and the front of the car is down hill. Is that in any way stopping the system from emptying of coolant? Wondering if I should momentarily start the engine to get it circulating and help it to completely drain?
  7. That's funny, the system has automatically masked my appropriate use of a word deemed to be rude! 🤣 To keep it clean, consider that ***** = tap!
  8. Finally tackling my coolant issue today. I have new coolant and a bottle of rad seal. Will give that a go before changing the radiator. Anyway, I've opened the drain ***** on the radiator, and was surprised that not much coolant has drained. The slow flow has now stopped, and my bucket is less than half full. I'd be surprised if even 5l has drained - but the handbook says capacity is 10.3l. The radiater was full before I started, so coolant was not dangerously low. Is it not possible to completely drain the system - or is there another drain ***** that I've not yet found?
  9. I went to my local camping shop yesterday to try some mirrors. I compared milenco aero and milenco falcon (would suit a star wars fan?). Both fitted almost the same, but at about £20 saving, I decided upon the falcons. My mirrors are not both fitted the same. On the driver's side, the mirror is at the bottom of the housing, so the towing mirror clamps nicely at the top. On the passenger's side, the mirror is slightly higher. The larger gap to the housing is still at the top, but it is slightly too small for one of the towing mirror clamps. I will need to fettle it a bit at the weekend to get a good fit.
  10. Hi All, I need a pair of towing mirrors to fit to my RX400H for my summer holidays. Before I start researching which ones will fit and which won't, I wonder if anyone here has any experience to share? Oh, and if you have any to sell, let me know!
  11. Biggest problems with using a smartphone or tablet are: 1) getting a GPS signal 2) finding a way to mount the device to the screen or dash. How do you do it?
  12. The seller should be able to confirm compatibility with yr car. I bought a new disc for my 2006 rx400h on eBay last year. They come in sets of about 4 discs which each cover different regions in Europe. Some sellers must split the sets and sell the discs individually. I bought only the one disc which I i wanted and it wasnt very expensive.
  13. Herbie, I think that you have demonstrated behaviour in the hybrid that is akin to a non-hybrid. When a non-hybrid engine revs above a certain engine speed, the charging circuit activates and the voltage at the battery terminals rises ( in my experience to 13.xx volts). In your demonstration, you showed the battery voltage rise to 14.xx volts when the inverter became active. I would think this would be sufficient to activate circuits in a caravan. In my testing earlier this week, I was only measuring the voltage on my leisure battery in the caravan: the voltage did not rise when the car was in the Ready state nor when the engine started or the engine revved. I must test again to see how the voltage at the car battery alters, and also the voltage on the output pins on the trailer socket.
  14. Hi All, I have an issue with my trailer electrics when my rx400h is attached to a caravan. I don't seem to be able to charge the leisure battery or run the fridge on 12v when connected to the car and travelling. I believe that the car is outputting 12v on the correct pins, and I believe that the caravan senses this supply, but the fridge and charging of the leisure battery don't seem to work. I'm wondering if the outputted voltage might not be high enough to trip the caravan relay to switch these functions on. Has anybody else had such an issue with their hybrid? On non-hybrids, the battery voltage can rise when the engine revs, but I don't know if this happens on hybrids. Is there a way to keep the engine running and or blip the throttle on the rx400h? Often when stopped, the engjne cuts out (as it's designed to), but this isn't always helpful for testing, or maintenance.
