Gummi pflege for the rubber seals or a smear of silicon based grease.
I used to have this for my old cars, the issue is that I'm not sure if the foam pad at the top won't be. Able to reach the window seals because of the plastic covering over them. Effectively the seals are a little recessed. Hopefully the autoglym stuff will work! The window certainly sounded better going up than when it did before I'd cleaned it. Tempting to do the other windows too. I'll probably buy some of that stuff to treat all of the other rubber seals though, so thanks for that!

The Gummi Pelegrín is the stuff to use, where I have difficult to reach areas I use some Cotten buds that I’ve moistened from the applicator

Or something like these

Well, it seems like the problem has been solved. Was only able to take it to 60mph but it was quiet at that so fingers crossed!

The car's MOT is due in around 2 months and I've decided on some preventative maintenance. It is a relatively common issue that the radiators can fail and cause coolant to leak into the gearbox. It is not too expensive for a new radiator, yet a gearbox rebuild will cost over 10x the amount, and that's even if that alone would save it, because it could damage the engine. On the Lexus forums it is recommended by several people, and a few have had the radiator issue and wished they'd have changed it beforehand.

The car was a bit hesitant to start on Friday. The car was fine on the Sunday before but definitely struggled a bit after not being used for 5 days, which isn't usually the case. Again, on Saturday it took a good 2 seconds or so longer to start, I took the car for a 40min drive and it has been fine ever since but I figured that the battery isn't holding charge very well so today I have just had one of these fitted

Pretty much the best spec battery you can get for the car. I tend to do a lot of short trips, the car can often go days without being used but usually once per week or 2 I will do 2x35-40min drives in a day which should be fine, so I think the old battery was on its way out.

Do you have to do anything to tell the car it has a new battery? Lots of newer cars (all of them now?) use coulomb counting to monitor the state of charge of the battery for intelligent management of the alternator and for stop/start; they integrate the current flow in and out of the battery over time so they know how much is in there. When you get a new battery the car might want to know presumably, they it then charges it more conventionally to know it's "full" and goes from there.

I know BMWs like to be told the battery has been changed with the dealer computer system, but I'm not sure what happens if you just don't bother and make it sort it out for itself.

You can probably tell if your car has this because there will be a thing on the positive battery terminal with a connection to the cars wiring loom.

Absolutely no idea! I was told my E65 needed programming, but I didn't bother and it worked absolutely fine for 2.5 years or so until I sold it.....

The car started fine and drove fine smile

Well, if the car fails to start tomorrow I'll let you know hehe

I must say overall I'm really happy with this car. Whilst it may not be especially exciting, I wanted something pretty reliable (in the scheme of old barges with big engines!) that was quiet and comfortable. I've had it for 10.5 months now, it's not let me down yet and I haven't actually had to spend a penny on it. Thanks to me helping someone out I got that battery fitted FOC today. But even if I were to add up the total costs what it WOULD have cost me since owning it, it's probably only a few hundred quid which isn't bad at all!

Did you not pay for the radiator then either? If so, fine work!

They were not able to get the radiator done at such short notice so it will be getting done when it goes for its MOT, which will be approx 4 weeks time. The radiator is purely preventative, but I'm supposed to be going away Saturday (renting a cottage 250 miles away) so I wanted the battery doing ASAP just in case it failed when I was away.

Go for an OEM Denso radiator when you replace, there are a few pattern alternatives, all of dubious quality. I bought mine directly from Lexus at around £300 (an uprated version with a bigger diameter nipple: the originals are easily snapped) but Rock Auto have them at around £180 including shipping to the U.K.

Thanks for this. I did say it was best to get a Lexus OEM piece so that's what it'll be getting. Good to know they have an uprated one, I'll ask for that!

Cheers.

Edit - just had a look there.... Are you sure denso is the OEM, as that appears to be a bit over £100 and a Nissens one is around £180? Thanks.

Denso is the OEM supplier for the LS460 rad. Lexus forum users mostly have dementia and I struggled to ascertain who made them initially. My “can’t be arsed” threshold is pretty low so I ended up ordered the correct part from my local dealer and of course did the research after I spent the money.

This is the rad that came off the car, which I believe was the original. No idea why I took a photo.



You can see the Denso’s underlined “D” logo. The brand new rad was identically stamped, but the top nipple was larger and thicker ( the originals are very easily snapped, usually when other works are carried out. Ask me how I know). so I presume this was an update. The original coolant pipe still fits over, but it’ has to be stretched. Worth ordering a new one.

They are indeed around £100 on Rock Auto with around £80 postage.

Thanks very much for this mate. I'll send the details to "my man"

No prob Ross.

Last aside- you’ll be doing a coolant change at the same time so make sure your man uses the proper Toyota “red” coolant: this could be overlooked and is probably the main reason the radiator innards corrode in the first place.

250 miles through pretty miserable conditions yesterday, but the LS was unflappable. That was the longest journey I've done in the car since getting it. Overall about 4 hours of driving, the last 20 miles took about 45mins due to a very narrow (and long!) B road.

about 1-2 weeks and I'll get it booked in for the new radiator and coolant pipe(s) and MOT. Fingers crossed all is well.
