  1. I think that they were all Mazda by then... anyone? (Crossed post.) Jonathan
  2. What year is it? And can you find a drain plug on the left side in addition to the filler plug? Jonathan
  3. Do you want to drain and replace? Or only check level and top up? And which gearbox is it? Jonathan
  4. Yes, you can fit a new nipple. Bike technology. There are some suggestions in the archives. Jonathan
  5. "A good tip if they are a bit loose is to buy some heartstrings sleeve." Heatshrink? Jonathan
  6. If it's all dry externally ... What's the appearance of the coolant and the engine oil? How are you filling it and trying to make sure that there isn't any air left in there? What sort of thermostat do you have, and does it have the magic hole? Jonathan
  7. I don't understand what you're observing. Black/Green is the usual colour for the feed to the fan. Is there a Black earth in the same connector? I suggest disconnecting at that connector and measuring the voltage between the two terminals on the chassis side of the connector. Ignition OFF. Ignition ON but engine cold. Jonathan
  8. "When cold and the fan not running I get 12v at the fan plug, when it reaches 97 and gets the signal from the ECU it reads 12.5-13.5v is that slight increase in voltage what switches on the fan?" Where are you putting the other probe? And what colours are the wires to the fan motor? Jonathan
  9. If you'd like a wiring diagram please send me a Private Message with your email address. Jonathan
  10. Previous discussion. I can't find a template. Jonathan
  11. "... I would not expect to see 12v while the engine is cranking, given the small battery. It is likely to be nearer 10v." I'd be concerned about the state of the battery by anything below 10.5 V while cranking. And some electronics on some Sevens gets unhappy. Jonathan
  12. Well done. Thanks for the update. And check that loading at the brackets as you remove it! Jonathan
  13. As above. Please let me know if you'd like a copy of the Assembly Guide. Jonathan
  14. "It would also be worth checking the earth side for continuity." Yes. And before removing the pump I'd run a good feed and earth directly to it. Jonathan
  15. Please add a photo. Jonathan
  16. Jonathan Kay

    Fuel Gauge

    Thanks for the update. Jonathan
  17. Discussion with some part numbers. And more from 2019. Jonathan
  18. Caterham Service Schedule (Duratec) Please let me know if you'd like a copy of the Handbook. Jonathan
  19. Welcome to the club within the Club! : - ) Jonathan
  20. NB Club discount at Halfords. Jonathan
  21. As above. But if it's a metal can type you can also transfix it with a screwdriver and then use that as a lever. Jonathan
  22. I try to avoid any sealing compounds for radiators or hoses. Jonathan
  23. Yours doesn't look like the same sort of fault that has recently affected so many aluminium radiators. But I'd still check that there aren't any twisting or bending forces on the radiator from the mountings. It should clamp up nicely without these forces and you can check when you take it out.
