Mobil Coolant

[Kite]

I am completing a timing belt/water pump replacement on the family hauler (thanks to OTRAMM for the guidance and directions). I have searched coolants extensively on the forum and most users recommend sticking with Toyota Red or Pink in some cases. I have access to Mobil Delvac Extended Life coolant and Mobil Heavy Duty SCA Precharged coolant. The Delvac is pink and the Heavy Duty is red. Reading through everything, it would appear the Delvac should work but I was hoping someone more well versed in this area would chime in with their thoughts. Thanks everyone.

In doing some more research, the Heavy Duty has nitrite in it so that is out. The Delvac appears to be OK.

Why? Toyota Red or Pink are the same price, why not use something you can buy in most any city?
