Onan Generator Coolant Change

[fishheadbarandgrill]

Has anyone drained and replaced the coolant on their genset? The manual says every 2 years. Reading up on the procedure and it looks like a real pain in the butt, especially draining the block.

Thanks,

I did that in the spring. Unfortunately, I didn't do the work myself, I had it done while the engine was being serviced. The mechanic commented that the Onan was more difficult than the Volvo, FWIW.
