Slant 6 Coolant Flush

Yes, and if you want to use a chemical flush by pass the rad and plumb the two hoses together.If you run at idle keep a eye on the temp gauge and shut down if it gets to the high end.Slants are cold blooded and as long as the water is circulating you may have as much as 10-15 minutes run time to loosen the gunk in the block.
