RX 450H Engine Power difference
BROUWERS replied to stecko's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
From Wikipedia: "For the Lexus RX 450h, the compression ratio was 12.5:1. For the Lexus GS 450h, the compression ratio was 13.0:1." https://en.m.wikipedia.org/wiki/Toyota_GR_engine#2GR-FXE -

Rx400h cam belt change.
BROUWERS replied to Keeling54's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
No special tools needed. I only had to buy a puller for the harmonic balancer which I didn't have before. -
RX400h Shock Absorber compatibility
BROUWERS replied to engine's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
I'm looking at replacement shocks as well, but after reading reviews for the KYB and Monroe ones, I'm leaning towards OEM. Price is not too bad: https://www.lexuspartsdirect.co.uk/parts/lexus-rx/lexus-rx-phase-ii-2004-2008/lexus-rx-2004-2008-steering-suspension/lexus-rx-phase-2-n-s-r-shock-absorber/ It seems all 2nd gen RXs share the same shock absorbers looking at the part numbers. -
RX400h and flat main battery
BROUWERS replied to Mickscores's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
I will see if I can provide some numbers testing my small solar panel over next weekend. -
RX400h and flat main battery
BROUWERS replied to Mickscores's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
The OBD port does have a live 12V pin when the key is not in the ignition, so I've been using a solar panel connected to the OBD in the past with good results. As standard, the cigarette lighter sockets are not live when the ignition is off, so dont try and connect a solar panel to one of those. -
Fuel low light - game of nerves :-)
BROUWERS replied to DJ Les's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
Summer temperatures, no highway driving, max tire pressures, minimal luggage on board, no AC, minimal amount of cold starts, pulse and glide where possible, so basically no realistic conditions at all 🙂 Some fair hills on the way though. Calculated actual fuel economy was 51.74 UK mpg. -

BROUWERS replied to DJ Les's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
I once did well over 100 miles with the fuel light on, but that was on an experimental hypermiling run where I averaged 53.5 mpg (685 miles on one tank). I then managed to get 59.65 litres in there before the pump clicked and turned off 1st time, so in theory I could have gone another 60 miles. -
RX400h MP3 Playback

I believe only from the 2007 model year. -
RX400h temp gauge
BROUWERS replied to BROUWERS's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
Thanks for clearing this up guys. I guess only tech freaks like us want accurate information from our cars 🙂 -
RX400h temp gauge
BROUWERS replied to BROUWERS's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
On my other car, a classic Citroën, I do see the needle pointing at a higher temperature before and while the fan is kicking in. Surely it starts operating only from a certain temperature, let's say 95 degrees. It then quickly lowers while the fan is doing its work. My point is, how will I ever know my engine is overheating when a temperature increase enough to let the fan run is not registered by the temp gauge. @Jaystar77@NemesisUK I let the engine run until the fan kicked in as part of the coolant refill/bleeding procedure after changing the timing belt and water pump. A/C was off. -
On the very few occasions my radiator fan came on, I noticed that my temp gauge in the gauge cluster was not showing any higher temperature than during normal driving conditions. For me, this is kind of scary. As we know, the RX400h does not have a warning light for low coolant levels. If the temp gauge doesn't show high coolant temps either, then it has very little use, other than showing when not to stress the engine, because it hasn't yet warmed up properly. Did anyone else notice this?

Intermittent cruise control
BROUWERS replied to Arharh's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
Can't set a speed. I push the stalk into the SET direction, but it won't hold the speed. Happens maybe twice per month. -
Intermittent cruise control
BROUWERS replied to Arharh's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
I have the same issue since I swapped my clock spring for a cheap Ebay one. It will show CRUISE on the dash, but will not hold the speed. -
Rx400h Dip beam headlamps too low?
BROUWERS replied to welland's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
There's a threaded rod with a nut which take care of the adjustment. Pictures can be found in this thread: https://www.lexusownersclub.co.uk/forum/topic/86415-afs-sensor-replacementrepair/ Not sure about the calibration process, you'd have to check the Lexus workshop manual for that. Although I'm sure this can be found somewhere on this forum as well. -

BROUWERS replied to welland's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
Look behind the right hand rear wheel or even take it off to have a better look. It connects to the rear stabilizer bar. -
Starting
BROUWERS replied to Felix Downs's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
If you're saying the engine starts up when cold within 10 seconds of turning the key, that's fully normal. The hybrid system requires the catalysts and the coolant to warm up before going into "full hybrid mode". This, on a cold day can take up to 15 minutes of driving. You can read more about the stages of hybrid operation here: http://www.john2211.nl/Hybride_modi.htm -
URGENT HELP PLEASE
BROUWERS replied to Burroo 67's topic in RX 300 / RX 350 / RX 400h / RX 200t / RX 450h Club
It's necessary to do all those taps. Might take a few tries. -

The buttons aren't visible. It might take a few tries to get into the menu, but I can confirm it works. -

Without a multimeter try the 'secret' menu described in this video. Around the 00:43 mark, the battery voltage is shown: https://youtu.be/zLlh5TfbyRQ
