Great tip to maintain the radiator, this will surely help all the 2nd gen GS owners out there, and best part is that you don't need crazy tools for the job. 👍

Boom. I'm doing this tonight. Thank you! Sidenote: My wife has the 2001 GS300 Blue Pearl paint and the GS400 17 inch wheels. Yesterday I found a video on touching up plastic bumper and wing with baby oil and a little mineral spirits. And then you can seal it with ceramic seal. It worked. My wife's blue came back to a correct color appearance with just that. Although I haven't sealed it yet. I'm going to redo it when I seal it.

I just installed a new radiator, timming belt and water pump. My old radiator was just like yours but worse! Definitely something that needed to be addressed.

This guy is a GS400 lifesaver!! Love these videos.

I remember when I pulled mine it was pretty dirty. This is a good thing to do. Anything that can be done as simple as this to increase or improve the performance of your vehicle. Great vid bro!

Love your content Thanks for being a support for the Gs community

This happened to me after a rallycross event in my 1993 gs300. Started overheating halfway through the laps! Ended up buying a new radiator and saw this once i took the old one out. Good video!

I love this guys attention to detail what a channel..

Keep up the great work. Soon as I get off work I’ll be knocking it out. Mines only got 235k.. shouldn’t be too bad lmao 💪💯

Good tip especially after fall! Good vid brother👍

Nice catch bro I recently just replace my radiator since it over heated lol easy fix, also I think the fans might need to be replaced to cause my cooling cap isn’t tight enough it lets coolant come out but it’s good for right now I usually recommend amazon for good parts cheap af

You know what I’m going to do today!! Thanks!

WOW I am checking this out this weekend. Hopefully this works on my LS430 also.

That's the A/C condenser not trans cooler.

notification squad! Thanks for this video, helped a lot!

Your GS is inspirational

keep it up love the content !

Thanks bro!!

Great tip. One suggestion though. If possible, use compressed air to blow the trash out. You can do it without touching the fins and are less likely to bend them. I know I usually bend them just thinking about the radiator. :)

Hey man do you have any tips on taking off the harmonic balancer it pushes out and I believe needs to be replaced the belt slipped. I can not remove the bolt even with a breaker bar and cranking the engine trick.

Hey brother, not trying to be an know it all, but the thing you called a Trans cooler is actually the AC condenser. Loved the videos! Keep them coming!

Can I ask - does the Mk 2 suffer from the bad Radiator syndrome that attacked many Cars including Mercedes around the 2000 period? The Transmission connector running through the Rad used to fail and could result in Coolent going into the transmission? Is it a Japanese built Car and Japanese Radiator in the 2nd series? A Valeo rad isn't used?

If you bend a few fins its not a big deal... theres a tool we use for ac units called a comb... just like for your hair but its 4 tiny different sizes on a key ring and you just comb the fins and they straighten out

How long did it take your radiator to get that buildup? Is that the original radiator? So I'm trying to figure out how long would it take it to get like that because I just changed out all three of my radiator. 🤔

One of the first things I am going to do to the next GS I buy, I am going to replace the 20 year old plastic radiator. (had one blow on my 99 GS300, 260k miles)

Wow! I’ll to do this on my GS300 on my next day off! Thank you!. (225k)

Wow thanks

Hello,does you PWR,ECT,SNOW button light up

I had to put in a new rad about a month ago. The original unit I took out of the car was filthy..

Good info, honestly I thought this video was going to be about the lower ball joints

wow thank u

Mine wasn't so bad when I pulled the rad to do the timing belt early april

I've got 180k on my 99 GS400. I'll have check my radiator.

can this haopen on a 2nd gen ls 400 too?

The GS MKII was so perfect when it came to the Facelift...it was a Facelift in Name only..bcos the new grille and repositioning the rear Indicator lights is Subjective ...it didn't really add anything to the car😆..if you have a MINT early GS you won't swap it for a later model..

You want to be mindful of the condition of your plastic end tanks on the radiator. You don't want a failure to happen while driving. Might as well upgrade to all aluminum 😁

That top tank is old and brown. I'd be looking at a new radiator very soon.

Hey buddy

He damaged the radiator with the vacuuming... When I cleaned mine (2000 GS300) I sprayed it carefully with a water hose, and cleaned with an old toothbrush very carefully; I also very carefully vacuumed lightly with brush attachment. In proper order... Remove what you can by hand. Lightly, and very-very carefully vacuum with brush attachment; use the toothbrush to loosen debris - continue with vacuum as needed. Once you got it good with the vacuum, spray with water on the "Cone" setting if possible. Please people... Be careful when cleaning your radiator or you might as well replace it. You could even avoid vacuuming all together to avoid damage as it's very easy to do - remove what debris you can by hand, toothbrush, and by spraying with water on a safe setting; I use "cone". Sorry... I can ramble.

Awesome thanks!!!! Mine has got only 97,000 miles (1999 model year) But I'mma check that out.

Checkline now

You need to replace your radiator anyway. That tank discolouration will lead to failure soon

Could this be why my ac blows hot air? Ima check it out in the morning

what happened to the swiss cheese mod?

you need to bend those fins back open where you cleaned. otherwise there is no point of cleaning it.

Did this when i swapped out my radiator but mine wasn't anywhere near as bad as yours was.

You did end up up smashing quiet a few of those fins, never a good idea to use any sort of hard tool for it.

Have you ever driven the 1st gen lexus GS?

You need a new radiator, when top turns brown it's more likely to crack.

My Gs brake master cylinder went out last week 😢

Yeah this one was different, Idk I guess it was just that one video. Lol

why not get a blower? and blow it loose?

This is my wife's 2001 Lexus GS300 190k miles and Pearl Blue. I want a GS400. Drive a CT200h now which is really a Prius in disguise. kzfaq.info/get/bejne/bMqiopSU0MjGp2g.html

Where’s the dyno test 🤬

Not too sure how long you've been working on cars... but that is not a trans cooler. And you should never use a brush on a radiator. Simple Green and warm water would have worked a lot better
