I don't claim to know as much as the Mercedes engineers and I know that around town with the auxiliary fans in operation the shroud will allow the aux fans to force more air through the coils. But since 90% of my driving is on the highway and it seems like lots more air would be forced through in that situation, I'm of the opinion that I'm better off shroudless. Does anyone have experience or input on this?
A cursory driveabout this evening showed marginally colder vent temps and I let it idle in the driveway for a while with no overheating but I am reserving final judgement until I drive to and from work in 90-100 deg weather.
For the record, I have the dual fan setup.
Thanks for any and all commentary.
Chuck.
