Drain Coolant and Refill----No Need to Bleed Air From System?
My 03 Silverado 2WD with towing package has 78,000 miles so I figured it is time to service the cooling system.
I was going to open the petcock on the radiator and drain the system and then refill with a 50/50 mix of coolant and distilled water.
Is there no need to bleed the system after I drain/refill to remove air pocket(s)?
Thanks for any tips or replies.

After you drain it you need to run it with the radiator cap off until it gets hot, that will let the air purge out of the coolant system.

I agree with pete. I don't believe there are any othe special procedures required The process he stated above is the same that I have followed on every motor I have ever flushed.Trevor - Huntington Beach, CA

OK, that was pretty easy. It took just less than two gallons of the mixture.
Thanks for the replies.
