Have only realised you made a remark - Not a worthwhile one anyway - stupid or not I have a suspicion that you may think you know more than you actually do, as the car is still on the road passed each MOT with flying colours and starts every time so methinks I can make a thread to report my experience. As my level returns to its level thus one can say no water loss your sentiment can be ignored - I wonder how many have followed your advice and thrown away the car? Enjoy Kent and the lorry park on the M20.

Any more news about this issue?

Graham - great info, well done. Update on where wiring is as requested above would be very helpful.

Interesting - no one wants to add to this conversation? Now back to resolving this after knee op- so any advice out there?

Excellent spotting of the leaky radiator. I am still investigating and am sourcing an egr cooler. Definitely not a leak in my scenario - just over pressurising.

James, I had written a Sticky Note - not quite certain how they work, just about to send it in response to you and it disappeared. In a nutshell we have a friend who has moved to Telford, so could try to pop-in to chat over a cuppa mid-november. Once we have a cunning plan sorted will make contact. Keep the faith with the Lexus.

Resevoir is good - loss of water only through the exhaust port. Have met another chap who had a crack like you suggest. Also replaced pressure cap to make sure. Confident in egr cooler - now working out a method of testing this whilst on engine if possible.

Passed MoT with flying colours - No worries the inspector said.

Hi James, you sound a little dejected with your Lexus, a pity as they are really good cars. My love affair with Lexus started 4 years ago when after reading good reports about them found a battered GS450h and rebuilt it over a winter when recovering from a broken collarbone. I am not a mammoth expert on them but have learnt to maintain them with self-learning about the electronics to overcome many minor irritations that have been experienced. Where in Staffordshire are you? I leave Ireland on Wednesday and return to Somerset on Thursday via Pembroke / Bristol (M4/M5). I should explain all of the Lexus cars my wife and I own have a story behind them - some funny, some wierd, and some mad. We are just general run o the mill folk who have bought some Lexus for enjoyment as well as work. The IS220d car with this problem has only 107k and is staying in NI while I consider the options. I have a second IS220d - black '08' and only 123k - runs like a dream and used to get me up and down the M-way for work until Feb this year when I finished the contract. If you fancy a project I have a '58' IS250 in the garden awaiting my attention - stupidly won it on fleabay (long story) and forgot to check if a wheelnut key was with it. So stood up in back of garden waiting for me to get the wheels off. Should you want some knowledge about GS450h have you considered options and year? I have an '06', black SEL? I also have a '59' SE that wife really enjoyed until she decided it was too large - so I got a Ct200h for her and kept the GS as it has only done 32k. Should you want a trip to Somerset - Taunton, for a chat and an adventure please let me know. Bring the IS220d and maybe we can resolve the issue you have. Cheers. Stan

My initial start to resolve this problem was to visit a local scrapyard to remove a cooler - little did I realise how awkward it would be. After an hour had to leave as he wanted to close - as it was 12 noon. Had to learn on the go - removing the exhaust manifold is not simple as to access one bolt under the manifold outlet is a torment. To displace the turbo to get to the cooler is also a headache with all the ancillary pipes. Reviewed options and found some coolers for sale on fleabay. Noticed a circular seal is needed between engine block and cooler and thought oops - perhaps a new one would be needed as most coolers being sold do not have it on. Now thinking about how to test the cooler before making purchase - to confirm it will work correctly our thoughts are to pressurise the exhaust inlet, blank the out, then listen if noise is heard in water inlet. Any thoughts by others welcome. Possible option is to place in bowl of water to see if bubble come out of water inlet. Discuss anyone.

Hello Colin, Many Thanks for this idea - I suspect this is the cause in my scenario. I shall be investigating this once time allows after MoT on Sunday (Yes Sunday - in NI they have a huge backlog). Hope the item is easily removed.

Experiencing same problem - on 07 IS220d, only 107k, MOT on Sunday - here in NI, hope it passes. Cannot find info on changing head gasket - strange omission on this forum site - or is it me?

I also have an 07 with same issue - would like to know where gasket fails - if the location is the same for most of these problems.

Just changed the front pads on GS450h after 31k - pads are similar in size to a Ford Focus, so even with Brake assistance from motor regeneration the wear is similar to a typical car. Car often driven by wife who treats it like a pussycat, whilst I drive it with gusto at times. All pads wore evenly and true.

Have you found a solution?
