  1. Thanks for your help everyone. £317 for the pump and £50 for my local Indy to fit it and normal service has resumed. No fuses blowing. No error messages. Pump clearly running when I open the coolant cap. Thank you everyone. Sent from my iPhone using Tapatalk
  2. Given that no errors pop up until it’s been driven for 15 minutes even with blown fuses I suspect the only feedback to the ECU is via a thermostat telling it the inverter is getting too hot. I should get underneath to have a look at pump tonight. Sent from my iPhone using Tapatalk
  3. Sounds like you know what you’re talking about. So new pump required you think? There’s apparently no outstanding recall for my car. Should there be? Sent from my iPhone using Tapatalk
  4. Thanks for the help so far folks. Some progress today following the advice above... Its eating 10AMP inverter water pump fuses within seconds. I’m still looking for an image or diagram of the location of the inverter cooling pump if anyone can point me in the general direction of one? I suspect pump is jammed.

  5. Does anyone have any drawings of the cooling system or a how to for swapping the pump? Out of curiosity, where’s the cooling reservoir for my engine if this is just for the inverter cooling system? Sent from my iPhone using Tapatalk
  6. Thanks guys. Does anyone have a diagram or drawing of the pump? Tracing the pipes, I’m assuming pump is in the scary looking box with orange cables and a cover saying ‘this isn’t a battery you tit, it’s in the boot. Stay away from this scary high voltage thing if you don’t know what you’re doing’ or words to that effect. The coolant reservoir seems to be linked in my GS for engine and inverter coolant. My OBD reader tells me temperature data but I think it’s just for engine coolant rather than anything else. Sent from my iPhone using Tapatalk
  7. Thanks guys. Plenty coolant in the reservoir I can see, not sure if it’s engine or inverter coolant. How easy is the pump to change? Is it an eBay and DIY job or a Lexus main dealer thing? Any easy way to diagnose? I’ve got an OBD reader if that’s any use. Or can I test the pump in place or on a work bench? It had a main dealer service at 110k but local garage did basics since then, just oil and filter stuff. Have been meaning to get the hybrid system checked to get the warranty but haven’t been in yet. I’m not sure if coolant pump would be covered. The ‘almost certainly’ wording inspires confidence. Thanks! Sent from my iPhone using Tapatalk
  8. Anyone got any hints or tips to diagnose this issue on a 2009 GS450h with 130k on the clock? Comes up after around 15 minutes driving. Clears after 12v battery removed. Doesn’t come on if you drove sub 15 minute journeys. Sent from my iPhone using Tapatalk
  9. Are these still available? Sent from my iPhone using Tapatalk
  10. I got about 15000 out of the rears (and I drive like a *****). Another set going on soon after an alloy refurb. Fronts half worn, if that. Sent from my iPhone using Tapatalk
  11. Has anyone got any experience of coolant leaks on a 2007 RX350? Is it common and easy to pinpoint what the issue is? Sent from my iPhone using Tapatalk
  12. Thank you Is there a summary of the various common torque settings for the DIY stuff anywhere? Thanks. I got the cabin filter from ECP for about £8. It’s in the glove box isn’t it? Sent from my iPhone using Tapatalk
  13. I must have done at least 1000 miles in varied Scottish August weather by now. So far they’re very good. Had tracking done at the same time so will keep an eye on wear. Sent from my iPhone using Tapatalk
  14. Hi all I picked up discs and pads with 50% off at ECP. £150 for front discs and brembo pads including cabin filter and some air con bombs seemed too good to pass up. Does anyone have the relevant torque settings for a front disc & pad change please? Come to think of it can anyone point me in the direction of a service guide for a 2009 GS450h please so I can find cabin filter and other bits and bobs too please? Sent from my iPhone using Tapatalk
  15. I need to change front discs on my GS450h. I’ve done it before on x-trails, Disco3, IS200. Is there anything unusual or strange I should be aware of on the GS450h? I take it it’s worth replacing calliper pins while I’m at it? Will do pads too obviously. Weird discs are sold as single front left/right. Never seen that before. Usually just pairs.
