    On my 2010 , I am monitoring the inverter coolant temp with the SCANGAGE2. Has anyone correlated that temp to the MG1 & 2 temperatures? I usually see the inverter temp running 10-20F above ambient temps, and am considering some winter grill blocking but need to know if the inverter temp is a sufficient guide to the temps at the MG sets. Reading over the gen 2 blocking posts, I see some rather high readings with grill blocking . Would only block the lower grills anyway, but want to be sure I am instrumented well enough before I do anything. Thanks

    The inverter radiator is behind the upper grill on the G3. I only block the lower grill myself.

    I block the lower part and monitor it with a ultra-gauge (for now) and notice no problem with higher temps. It does not block too much as the upper grill is still open, you should be ok in the cold.
