How To: Replace The Thermostat And Reseal The Housing On A 2002-2009 Lexus GX470

[@heykala9131]

Your video was a lifesaver.. my husband changed the thermostat in the parking lot of Advance Auto Parts...lol! Ty Bud! You're the best!

[@HowtoAutomotive]

Hey Kala glad to help. Thank you and your husband for watching!

[@benten6301]

how you know it’s thermostat. my 2010 lexus overheat

[@heykala9131]

@@benten6301 your right.. it did end up being more as of two days ago actually. The cooling fan went out, along with the water pump. If you're experiencing those type symptoms definitely get to a shop where they can check it out. Our's finished breaking down while we were trying to Evacuate Hurricane Dorian.. been a nightmare two days. We found a good mechanic that fit us right in.

[@benten6301]

Wow. I found out the coolant were low and no leaks so I top it and went for a ride the. I top off with coolant again. I think it should be alright going forward. Good luck with Dorian coming down in your area. Take care. Thanks for the response.

@@benten6301 Np at All! I really hope that solves it for ya! Best Wishes and Ty for the kind words. 🤗

[@Paiadakine]

Thanks man. I have the exact issue with my GX. You video is golden. Subscribed.

[@AccuFast2D]

Very useful content. Appreciate the way you presented your video repair. The links were very helpful in purchasing the OEM parts and other useful consumables.

[@robhow6105]

Amazing video. Everything very clear and concise. Could do without the Milwaukee M 18 fuel 3/8 impact every time you use the drill but you got to do what you Gotta do to get free tools

[@HowtoAutomotive]

robert howell Yeah I was a little pushy with that. I’m much better with that now. Thank you for watching!

[@tools4spoons]

Thanks for sharing.. What coolant do you recommend for an 2004 GX470?

[@Teague-k8v]

Great step by step video! Very helpful

[@raphaelness1239]

Hey there, I'm actually needing this process done on my vehicle and wondering what you feel is considered a fair price for this job you are showing? Let us know, thanks

[@caddylover3510]

perfect video for what i need! I couldn't figure out where the leak was on my wife's 2003 Sequoia until i pressure tested it and found the leak at the o-ring on the housing. When it was cold out (0F) it would leak and when warm out (32F +) it wouldn't. The expansion of the o-ring in the varying temps was throwing me off. Housing is the same and process is relatively the same for the o-ring replacement. Won't bother with the thermostat, but will pull the whole thing off in any case to do it right when it comes to cleaning and new RTV for the housing. Do you know what the torque specs are for the bolts?

[@brianf215]

This seems to be exactly my issue on my GX470. Finally found it... Always happened when cold on mine as well!

[@zp9814]

Same, only happens when cold. Thankfully it doesn’t leak when driving.

[@zp9814]

Super helpful, thank you! Does anyone have the torque specs?

[@nofd1977]

Great info brother! Im not sure if its my Thermostat or not. I got the bubbles out the system and checked the hoses etc. I will say before it starts to overheats from being on for about 10 minutes i checked both hoses and the big one going from thermostat to thr radiator is hot while the one coming out of the thermostats other side is still cold. Does thst mean its a thermostat problem? thanks

[@HowtoAutomotive]

nofd1977 sounds like the thermostat is stuck closed.So pretty common for them to be stuck on this particular model. It’s only three nuts and it pops off.

[@bobbybenn8822]

thanks for the video saves from buying the stretch tool. I hope that same procedure works on my son 2010 camaro ss

[@HowtoAutomotive]

Bobby Benn glad to help. Thank you for watching!

[@alainp1020]

Question: When you removed the upper radiator at 1:10 how much coolant do you expect to leak out? I'm planning to just replace the hose clamp with an OEM as I noticed there is coolant formation where hose meets thermostat housing and once in a while after driving I get out the vehicle and I smell coolant but there is no leaking on the ground. So once again how much coolant should I expect to leak out as I'd rather not drain the coolant completely from radiator as some people have said that I need to do. Thank you

[@bobbybenn8822]

great video. do you have any videos of 2001 acura 3.2 tl

[@Shalmaneser1]

I'm looking for information on replacing temperature sensor.

[@travisburk5193]

I don’t know where my coolant is going. Temp gets hot then goes back to half. Up and down constantly. I don’t see any leaks but I have to constantly add coolant. When I turn it off, the coolant in the reservoir is bubbling like crazy. Could this be a thermostat issue? No water in the oil or anywhere else for that matter.

[@HowtoAutomotive]

It’s a cool is low it is leaking somewhere. It’s possible the radiator cap is self is the cars. Also a thermostat in stock will cause overheating that could cause it to overflow out of the reservoir.

[@stevegantenbein979]

Very nice... Thank u!

[@largemouthbassman5628]

Thanks for this vid

[@HowtoAutomotive]

Thank you for watching!

[@willisholdenjr.9482]

Also you can clean throttle body,while you have everything taken off.

[@sowhydontyou5061]

Thanks for the video!

Thank you for watching!

[@refuse2lose_ceo_]

My radiator upper hose get really firm like it’s gonna bust. Any idea??

[@apesintanks162]

Did you find out y?

[@speakingfacts9271]

So my gx470 the radiator gauge goes up and down so I’m guess this is the reason why it’s stuck on open?

[@Marcos-ll5fs]

My wife's is doing the same thing. Was it your thermostat?

[@MS-ij1tq]

Thanks!

[@HowtoAutomotive]

Thank you very much!

[@jhovene16]

Thank you.

[@Brother_Lander]

My brother. You should do a video on a gx470 radiator replacement. With the coolant drain from the radiator and the engine. There's no good video tutorials on this. They're all terrible. Please!

[@splitadutchnfillerup5437]

Nioce!

[@Ron-Noc]

You got all that coolant on the belt. :(

[@grockmalano9455]

Why use the.. Right Stuff gasket sealent, rather than using the proper gasket?

[@HowtoAutomotive]

For the Portion where the silicone goes there is no gasket. From the factory it is silicone

[@timesofyourlife1]

I was thinnking the same thing and after reading the comment I figured it was designed with no gasket. I think I have the same exact problem.

[@timesofyourlife1]

@@HowtoAutomotive This was an awesome video, same exact engine. Every morning when I look under the GX on the passenger side I see a small puddle of coolant but I never actually see it leaking when the engine is running. So some one wrote that he had the same exact problem and that the O-ring for the housing expands when the engine is hot and then when it cools off the next day as it shrinks it will leak, so this is why I never see it leaking. I sure hope that's the problem since you made this repair seem so easy! I will go to Auto zone and do a pressure test to make sure. Thank-you!

[@ThiccJungles]

Seems like the GX470s are pretty easy to work on

[@Paiadakine]

Wait till you have to replace the starter.

[@brianf215]

The alternator is in a terrible spot, the starter is impossible to get to, and then there's the timing belt and water pump (which I won't do myself). Other than that, they aren't too bad.
