Hello:

I was recently given 3 complete Thermoking Refer Units. They all have the Mercedes OM636 engines in them. They all need overhauled and are complete.

1. Where is the best place in the USA to get parts? Thermoking has individual parts but no type of kit.

2. How do these engines compare to the Isuzu c201 engines when it comes to how many hours before overhaul?

I was told these were phased out because Isuzu engines cost less. I plan on using these for generators.
