Radiator & Shutter
Hey all, Iím in the process of working on my very first conversion, a 2003 Blue Bird with a Cummins 5.9 ISB.
Iím doing some mechanical upgrades and preventative maintenance as Iím able in the cold Wisconsin weather, and while working on the front end of the bus I noticed that the piston which actuates the radiator shutters is disconnected from the pin it moves and missing itís retaining ring. Iíve searched the internet and canít seem to find a detailed drawing of this shutter system, so I wondered if any of you have a picture or schematic you could share?
Iím not sure how critical the functionality of this shutter is to the cooling system - which is one of the systems that needs attention. The aging plastic surge tank has a very slow leak when under pressure, and I am searching for a replacement. As well, it seems like I have a pinhole in the radiator; after highway journeys particularly there is some escaping steam from the radiator.
How many of you with the Cummins drive train have experienced and fixed similar issues?
