On my Plus8 I removed a couple of badges to see if any effect on coolant occured. Result was no noticeable effect. I am left with a single central badge and a badge on the ends of the bar. The car does not overheat but in summer the fan kicks in more than I like. I may look at airscoops/ducting for summer use to see if the rad temp can be lowered a bit. The gauge shows 90+ on a run in summer in warm weather but creeps up in traffic.
Winter temp just touches 80 with very rare fan cutting in.
Having seen the video done by someone with tufts of wool to show airflow, the grill edge areas seem to have not much air going in so try your badges towards the outer ends of the badgebar as a start.
Your single badge ? Try mounting in the centre first. I doubt you will affect the coolant temp.
