Tundra 2019 coolant

I found the coolant level a little low - should I use Toyota coolant only or an aftermarket coolant?

 

Just add H20 Water and get the reservoir up to level @zeenith
There is enough coolant that a cup or 2 wont dilute it too much.

Keep an eye on the level

 

Toyota coolants are already diluted. It may not hurt it but I wouldn’t add more water. Use the right stuff on a brand new truck. For fuck sake.

 

There ya go @zeenith 2 assholes 2 different opinions.................... Survey Says Do what ever you want because the your the one that has to decide if its worth the drive to the dealer for coolant or service to top it off warranty for you.

 

Definitely bugged me that Toyota didn't top off my coolant when I took my truck in for a ToyotaCare oil change and tire rotation. So much for that 150 point inspection...

 

When we got our truck in 2019 I noticed the coolant was a little low the next day after it had been sitting over night.
The handbook says between upper & lower marks on expansion tank, for correct level, which in fairness it was.
My OCD got the better of me and I topped it off to the upper level mark with the Toyota coolant.
OCD is a bitch but I live with it. My wife thinks I'm nuts and she is probably not far wrong.
I do not use Toyota Care

 

You think that's bad. You should see me try to get the tire pressures exact using a tire gauge and the display. Either the truck or my gauge is off by some.

 

I’ll bite….what is your definition of “little low” and when did you check it, after it sat for awhile or before.

 

WOW !

 

Which ever PINK coolant is closest/easiest to get to.

I've used all the aftermarket PINK brands for top offs and coolant changes on all the Toyota's that come thru my garage. Works just fine.
