- Take my advice,
if you own a Lexus LS400 and you are having issues with your cluster and you believe your vehicle might be overheating…
Send your cluster out to get the CAPACITORS REPLACED first.
This very common problem will cause all sorts of weird issues with your cluster, making it unreliable.

By the way you can drain the engine old cooling from two drain holes under the engine , the location near the upper oxygen sensors.
Because old cooling will still remains in the engine if you didn't do drain through drain holes
Also you can fill it up with new cooling , without removing the upper filling bolt .
And that happens if you fill cooling before putting the new thermostat.
I did all what you did in this video.
Good work 👍
Good to know!! 👍🏻
My advice to you : do the ECU capacitors from now , before you are facing unnecessary issues.
Its very easy .
Just take off the ECU .
Open it .
Take the board with capacitors out .
Go to the capacitor store .
As for exactly the same .
Take the board to a laptop's workshop.
Let them replace it for you.
It should be very cheap.
Good luck 🤞
I need to try this my Ls has a dead speedo and temperature only gas reads lol
💯 it’s the cluster capacitors, sent it out to get repaired
Something I didn’t follow in this video. I had a 1995 LS400 with a thermostat that opened at about 195-200F and that’s where the car sat at operating temperature. And the cluster needle sat right where it was in your video. I understand using the heat gun on the radiator hose but wouldn’t the exterior of the hose be a little cooler than what is inside it assuming it has at least some insulation properties?
That’s correct, that’s why the gun reads 165f +- , operating temp on a 1996 ls400 is about 180f max. So what’s there not to understand, the computer at times said the vehicle was at 215f (which would indicate a overheating condition)
The point of the video if you watch the whole thing is that regardless of your ls400 condition, get the pcm and cluster capacitors replaced.
Very well know problem.
(They leak overtime, creating all sorts of issues)
im the same way with the rad hose clamps! Always put them back in their witness mark!!!!
Absolutely!!
Shows you have pride in your work.
Thank you for watching!! 🙏🏻
Not ocd at all. Those kinds of things wink loudly at you once you have worked on cars even for a little bit.
Very true! Force of habit.
Why didn’t you hook up a scanner at the beginning?
I did Budd
What year...how many miles on the car. Thanks for posting.
It’s a 1996 with 135k miles. 👍🏻
those thermostats are rated for a certain temp anyway. you can get them to open at higher or lower temps than OEM but bases on the needle on your dash i would assume the new one is working. I guess that little digital tool is giving a false reading like you said.
Yup, until those capacitors on both the cluster and the PCM are replaced. All of the readings are inaccurate.
What did u use to take off the sensors?
Sockets wrenches, whatever fits.
Just got a 91 today scared
Good luck!!
You have bleed bolt there on top were you replace the short hose
Yes I sure do 👍🏻
Thank you 🙏
Great video!
I think the FJ Cruiser is easier to maintain than the LS400. Do you agree?
Oh my friend, do I agree!! 💯
(Out of the projects I’ve taken, since starting this UA-cam venture, I lost the most $$ with that Lexus)
No longer my problem.
@@VikingsGarageSorry to hear, that was one of the reason I had sold my 20 old IS300. It was a great car but age made it a time bomb waiting to be disastrous with full of electronics….I dislike cars with too much electronics…what a contrast to problem free Toyota Corolla or Camry of that same year 1990.
@Thankyou_3 unfortunately very true, LS400 is a great car but get ready to have a constant electric riddle. What I didn’t mention in the video is that the same type of issue also affects the PCM.
For those reasons and more a much simpler and just as reliable Camry of the same era is indeed a much smarter car to own. 🤷🏼♂️
Did it fix the speedometer
It did not.
1993 with 255K maybe I’m lucky I have cero issues with it
You mean Zero…
