hi there I just did regular service on my es 300h 2013 model
after changing engine coolant and invertor coolant,engine oil,and transsmission oil .
That task was super fast and easy .
After going around suspension and sway bar bushing lube and checking for freeplay I did notice two plugs for additional liquid just under drive shaft under driver side.
what is those plugs for ???

Does 2013 es 300h has some mini drive shaft lubricant or is for something else looks like 10mm hex bolts ,
veru close to invertor cooland drain plug.one is on top and one on bottom
I have never saw those before.

will post picture next time when I put car in the air in garage.

just wondering what king lubricant or oil goes there.???

The hybrid does have a separate transaxle that takes fluid.

thanx for your reply,but what kind of fluid is it?
is it oil or grease or some coolant,do you know?
I didnt open yet,but also I was thinking could be some measuring port or pressure relife valve.....
this gonna be interesting.....
work in progress

Check the owners manual, I recall it’s the same as the trans, but check to be sure.

Hi again,
here is the pictures of that .

As you can see driveshaft runs thru it. Top plug was marked with yellow ,I assume that is inspection port or fill in Port. Did
anybody checked with mechanic what is that port for?

Here you can see better it's above oxigen sensor....plugs facing passenger side front tire.

Here is couple more images ,


Here you can see top plug is marked with yellow middle one is far left on this picture ,and on the very bottom is plug where I was releasing transmission fluid we.
transsmission fluid was from Toyota WS .

This is drain plug for invertor coolant.just to make sure I did indetified it.
so now there is no confusions,we have location for drain transmission fluid
Drain for invertor coolant
Only those two left ....that I don't know what is it for.

Side view


Drain plug for transmission fluid is located on very bottom ,so the other 2 plugs are above this plug

Now it's better view of all 3 plugs. Bottom one is transmission drain plug. Top two are unknown ,can somebody shed some light here please

Can you please post how you did the transmission oil change and where did you get the transmission oil from?
Thank you.

Also I am sorry I do not know what those other drain bolts are! You are certainly more knowledgeable than me..

ZES transsmison oils I bought gfrom toyota WS transsmission fluid (red colour of the new flud,1 lit blck bottle.)
for this es 300h I have used 4.5 lit.
next time when I have to change transmission oil I will get some pics.picss
it is very simple to do.yu oneed 10mm allen key to unscrew drain and filler plug.

filler plug is located on the driver front side under plastic shield which needs to be removed using soccet 10mm.
allways remove filler plug first to make sure you can add fluid .

I have used small 1/2 lit. injector with small hose to add WS transsmission oil .
Thare is no transsmission oil filter.
I have collecting old fluid in measuring bin that I do know how much new oil to put back in.
all procss on the hoist was about 1/2 hour.
I do change transsmissin oil every 60-70 000 km,
that is just my routine but dealer could recomand different.
oil replacement is much easier on es 300h than on gs450h
next time i will post some pics too.

cheers
