Your Prizm looks just like my 97 Mazda Protoge. The grills look the same. I used the shrink wrap plastic that you put on windows in your house to cover the entire lower grill block. I have a scan guage and never get over 205 degrees.
It cost me $1.64 at home depot. When it starts to warm up I'll watch the temp and if it ever gets over 210 then I can just rip it off. I'll spend another $1.64 next fall.
Check my fuel log and mod history to see the other things I've done.
I know ford and mazda share platforms but your Prizm and my Mazda are real close.
