ok, I have a 1998 ES300 and I was wondering about the collant. The manual just says use only ETHYLENE GLYCOL (EG) which is green I believe but my car has red collant (ELC) in it.

I know you can not switch back and forth due to see and pump issues so does toyota/ lexus make some sort of red collant but is EG?

Need some help

 

The factory coolant that came in my 92 LS, and is still there, is a redish color. I suppose they just keep adding red dye #3 until they get the tint they want.

 

Good one! I asked lexus and they are clueless on this issue.

I know EG collant is green and Extended Life Collants are normally red, orange, and purple). You CAN NOT mix them. ELC is dex-cool kindof.

Lexus said it is EG collant just dyed red. okay.
