$3.75 Radiator Flush WOO HOOO!

Went to Advance autoparts and picked up one of their Prestone Radiator Flush kits for $3.75. Works like a charm. Hook up to the garden hose, and start er' up. Only drawback is the overflow tube didn't fit radiator cap on the trac, so a "little" rusty antifreeze got on the driveway. Also, I released the petcock on the bottom on the radiator to drain the gunk. Well I broke it reinstalling it, and had to get it replaced at Autozone ($4.00) It was extremely weak, and broke under low torque.



Man what a difference, and it needed it. There was a ton of rusty crap that came out of the radiator, and hoses. Also the fan doesn't "roar" when running the A/C on full blast (while the truck is hot) anymore. So, im assuming that I will see gas mileage increases. I highly suggest investing in this.

How often should it be flushed?

Ok, the Radiator flush cost you more than $3.75. What about the cost of the coolant? The cost of the replacement drain valve?

Still better then the $100+ is probably cost to have some one do it.
