Hey sorry I have been trying to find this information for hours and I just can't seem to figure it out.

I need to replace my engine coolant and intercooler coolant for my 2019 IS300 but I can't figure out how many gallons I need for each, would anyone have that information?

Also need to drain and fill my Automatic Transmission Fluid, how much fluid would I need for that as well?

Apologize for these stupid questions I just can't seem to find how much I need.

Why do you need to change these?

For the transmission fluid, I found this part number on an ebay listing: 83673KGBH
The bottle has a label reading "Toyota ATF WS". I think you'll need 9.2 quarts - but for a flush, you would probably want to use 10 anyway. (source: https://www.nalleylexussmyrna.com/20...t%207706187908.)

For the coolant, I found this one on parts.toyota.com: 00272-SLLC2
It's called "Genuine Toyota Super Long Life Coolant". True to its name, you probably won't need to replace that until about 100,000 miles have been driven.


It's just maintenance. I will be doing the same on my IS 500 - transmission fluid every 30,000-40,000 miles, and I am not sure yet how often to worry about the coolant.

You can buy a tool to test the radiator fluid.

Factory fill for current (2021 and up) IS': pink or some other color? From what I can tell from the reservoir mine looks...yellow. I know color means nothing in regards to usefulness but can indicate change out of OEM. Coming from FI cars OCI and coolant were tops in keeping, well, on top of.

It should be pink.

I have a random old photo of my IS 350's engine bay for some reason, and in the left of the shot you can just barely see some pink liquid chilling in the coolant reservoir.



Are you looking at brake fluid, maybe? Mine was yellow. The brake fluid filler is located at the back of the engine bay.

Yeah, that's what I thought :-\ I am looking at the reservoir just behind the fan shroud and above the oil type sticker.

So Ill look closer but looks like I might be part of flushing this crap out as I have no idea what it is. Asian cars usually are non-silicate and other chemicals while "NA" cars use silicate based coolants.

So actually looked close with a proper light. Wasnt yellow, just very low. It is pink. Gonna have to keep a closer eye on that.

Got SLL from Toytota where guy said oh we have concentrate. Woo hoo. Then he pulls out a bottle of red. Yeah, no. Not same thing. Ill take premixed. Darn was hoping for a concentrated bottle. Paying so much for distilled water irritates me!

Are you sure that ‘red’ wouldn’t turn to ‘pink’ when diluted?

It doesn't.
