Honda Jazz/Fit under grill

To improve the speed of warm up I am thinking of blocking the Honda Jazz/Fit under grill. I intend leaving the top grill as it is, for aesthetic reasons.
Has anyone tried this, and if so what were the consequences?

Block the top underneath so you don't see it AND block out the bottom like .....



You want as much air as possible going around the sides of your car, and over the top. Even if your grill block is behind the upper grill, it'll still be very effective because the air won't be smooshing its way through your engine bay and forced to speed up. Blocking on the sides of the lower will force more air to go beside the car. Hope this helps.

Do it, it works great. Helps with warmup times, helps the heater keep up with cold winters, and helps with aerodynamics. You need to watch your coolant temp in warm weather, though.

May give it a try then. I want to put the block on the outside, to begin with, so that I can remove it easily and quickly if the need should arise. It never gets particularly warm here nor, in the winter, does it get particularly cold.

It's possible to over-block the grille even in cold weather. Definitely need to experiment while monitoring coolant temps.

I have a secondary "flap" I can open in seconds - I opened it this week.

I have the ScanGauge that can monitor coolant temp. If I have a device that can clip on and clip off the outside of the grill I can use it for my short trips taking better half to work, then leave it in the garage when I take my longer journeys, when the car gets a chance to heat up. As at least a third of my motoring is trips of 4 miles or less it could make a substantial difference.
