My 96 has the booster pump for dash heat as well. I did forget to turn of the Diesel burner one morning on the drive across the country and promptly overheated things. Engine temps wouldn't get below 210. I had to pull over and let things cool off. Thats when I heard the diesel burner kick on, shut it off and problem solved. Right back to 185 where it should be.
