Replacing coolant recovery tank on Onan generator

[tankcj]

For those of you that have replaced the coolant recovery tank on your Onan generator, how did you remove the hose clamps? They look like they are a one shot deal and I will be replacing with a standard screw on band clamp but just wondering what the best method is for removing them.

I think op is wanting to change the plastic coolant tank and if I had a guess it's leaking because of a brass fitting splitting the tank.

Is this a common issue? I have had a small leak on mine for about a month now. It seems to leak as much as I put in the reservoir.

I have an Onan 7500 so I cant only see a sliver of the tank. Is there an easy way to check if this is my issue too?

Yes this is a fairly common issue for the QD7500-QD8500s where a small crack (or cracks) appear where the hoses attaches to the tank.

Ok, I found this video that shows one option for removing the crimp/pinch clamps.
