grill blocks
 
I'm thinking about doing a homemade grill block on the Prizm. But while sitting in traffic today(with no A/C running) I notice the temp went up to 202F. If I do a grill block, wouldn't the temp skyrocket while in traffic, even with the rad. fan going?

Oh forgot something. The normal running temp to 188F.

try half grill block and see where you stand...But if your thinking about using your ac, i would not do the half grill block either, wait till fall..

Yeah, I have to use A/C with 100+ and the heat index on top of that. So don't even do a half block right now? Any other simply aero mods that could work right now?

I'll look into those. But most I would wait on until the car is paid off.

My experience: I use a grill block since end 2009 on my black Civic. In summer around 60%, winter 85-95%. I don't suffer the temps you have now in US. But...strangely enough: in summer, if I use the AC my temps (engine and radiator) go down. That's because the fans are forced to run in such case (compressor AC engaged). And with approx. 40% open a lot of air is still sucked in.
Results of this mod are positive, but nothing more than a single % or so. I had much more notible result when going from 10W40 to 0W20 engine oil.
An my last mod was an engine block heater. Also positive result of course, but seem a bit less influencing than the engine oil. Allthough the period I only had the 0W20 without the EBH was very short. So I can't show any hard data as I did my mods a bit to fast one after the other.

i'm going to be creating a aerogrill for my cobalt soon it's not going to completely close off the grill because we need that air flow for a reason but it will allow the air to flow more smoothly compared to getting chopped up by my factory grill

Since GM and Ford are currently advertising cars with automatic grill blocks, I have to think there might be something to them.

If your temperature gauge reads hotter than normal;
1. Radiator shops usually don't charge to test the radiator.
2. After shut-down, pull the fan fuze, and feel the bottom of the radiator. if it is cool it needs replacement.
