Coolant Expansion Tank/Reservoir for OM616

Has anyone added a coolant expansion tank / reservoir to an OM616? I hate the fact that it just drains out on the ground when it gets hot.

Any suggestions?

First step would be to consider fixing whatever is making it get hot.

The easiest thing would be to simply install an "overflow" bottle (different than an expansion tank). This simply will catch any spillage, and you can dispose of it or pour it back in the radiator. You can get universal overflow bottles at any auto parts store. Or, you can make one from any plastic bottle.

If you want a true, stock looking, expansion tank you can install a 300D turbo radiator and expansion tank. Beyond those parts, you'll need the hoses that go from the radiator to the expansion tank, and the bracket that holds the expansion tank to the passenger side fender.

An expansion tank properly designed is a great help to cooling...
as it allows the system to purge itself of all air...
