Just bought a 2003 MB CLK320 (88k miles) for a commuter car. Better than my suburban on gas. Small car, but comfy seats.
Has a cool feature on the climate control. Button labeled REST. It's a residual heat function that turns on a small electric cooling pump (I think) and runs the hvac fan on low to continue heating the car cabin with engine off, or key out. Helpful for a run into a grocery store on a freezing day to help keep the car warm.
However...
I'm thinking even in the summer after a spiteted run, or anytime when parking for a while, I turn it on to help cool the engine, just a schmekle faster. It automatically turns off after 30 minutes or when battery SOC is too low to sustain.
It would effectively recirculate engine coolant and extract the heat through the climate control. Would add heat to cab, but if I'm gonna be parked for a while, say, when I get home from work, the cabin heat will dissipate.
Any foreseeable downsides to using this feature on yhe summer?
