Hey guys just a question about flushing my whole cooling system. I am changing my T-stat so I figured I would do a full flush. My question is how do I fill the whole system with 50/50? I understand I could fill the radiator, but does that fill the "whole system?

 

You have to keep filling. I take off the radiator "spud" and fill radiator, and the coolant jug to the mid point and idle engine, with right tire on a ramp or curb. When coolant comes out the radiator from expansion I put the plug back in. Goal is full system and no bubble sounds under the dash.

No, you just use 50/50 premixed coolant. Comes that way from the store. Get the green color.

 

Like Buzz said buy the 50/50 premixed stuff, you will need 3 gal.
I use Wal-Mart brand, it is actually Peak.

 

Cool guys thanks so much. My worries come when starting it and there is no coolant besides inside the radiator. Much appreciation guys thank you.

 

You fill the radiator, then fill the coolant tank, then bleed the system.
