Jon, You said that you had your radiator routed. Do you know the best way to flush a radiator without removing it from the bus? What type of flush is best? My 8v92 is beginning to heat up in the western mountains during the summer on I-8 from Eloy, Az to San Diego. My temp gets to 205 and I then pull over to cool down. May be forced to remove the radiator but will wait for your advise. Thanks for the post on manifold gaskets. Replaced my gasket yesterday. Glad you told about anti-freeze when bolt and stud are both removed. I drained the radiator before starting. Replacing the manifold gasket was not as hard as I thought it would be. Thanks
