Tom,

I have been closely following this thread. I think that you have stumbled across something that I had not even thought about. Since I bought my bus used, I have no idea of what was done to the radiator fluid before I got it. As I read your posts, you have run into loose bolts along with seriously degraded hoses. We all know what can happen if you get a pin-hole and mist coolant onto a hot turbo.

That caused me to do research on my C-12 Cat engine. In my case the hoses to the filter are a source of many failures.

Since I am a better-safe-than-sorry kinda guy I have come up with a plan:

I am going to get the Cat dealer to dump my existing SCA fluid, flush the radiator, and replace with the Caterpillar OAT fluid. That will eliminate the need for a filter so I will get them to remove the filter and hoses. Finally, I will replace all the existing hoses with the new ones with super-duper clamps. While in there I will get them to verify that all the bolts are tight.

Does this sound like a reasonable plan for a 10+ year old coach?

Cheers,
bill
