I recently purchased a 2006 Inspire with the Cat C-9. When I drive the coach a short distance and the engine doesn't get over about 160 degrees, when I stop and shut the engine down it leaks coolant from the area underneath the radiator. If I drive the coach long enough to get the engine to full operating temperature I don't have a coolant leak when I shut the engine down. I've looked over under and around the radiator area as best I can but I cannot spot the leak. Anyone have a similar issue they resolved?
I live in the Sacramento area and would appreciate any recommendations on there to get coach serviced.
Thanks Roger
Hello, did you ever get this resolved? Wondering what the fix was?
These symptoms are indicative of the radiator issues common on many coaches. There are really only two choices, remanufacture or, replace. So far my remanufacture is holding up well, after 7 years.
I have read that the true issue is the way the radiators were mounted. There is a significant difference in the coefficients of expansion between the steel mounting frame and the aluminum radiator. Thus, the radiator literally pulled itself apart during the heating / cooling cycles. Make sure any repair includes modification of the mounting supports to allow freedom of movement.
