On our 2006 the coolant reservoir tank looks discolored. It is yellow and almost can’t tell where the pink fluid level is. Was this white and yellowed over time?
Apparently something got to it my 04 is white still pink fluid In I just changed in it. 09 same. SM-A715F ?
There is a yellow coolant Engine Coolant – Choosing the Right Type for Your Car | Valvoline™<br />
What I want to know is if the plastic was originally white then turned yellow over time or it was like this when new. Washer and brake fluid tanks are white. Here is the picture.
As confirmed in the other posts, it has a yellow color. If you want to see the level easier, shine a flashlight in through the side and it will illuminate the coolant so you can see the level easily.
