electric water pump???

I've had a Mezerie 35 gpm on my car occasional use car for almost 5 years now and never had a cooling issue - actually I have an issue of it running too cool in cool weather. These pumps don't have a bypass on them so you can't run a T-stat unless you drill holes in it. I run an orifice plate in mine and it runs quite cool (typically 180-190 in hot weather, 160 in cool weather)..
