If it's a newer car with an ECM/PCM, you'd better not go any lower than a 180. If the engine never reaches a set temp, it will stay in open loop and get horrible milage, and wear the engine out faster. Even the oil needs to be at a certain temp. before it fully protects your engine...Which is why I never hotrod until it's fully warmed up...

As far as vatozone 'n' Ho-reilly, If it's a pump with stamped steel anywhere on it, turn around and walk out. I bought a pump at autozone for my car that had a stamped steel impeller. It was a piece of crap. I took it back and got one with a cast impeller. It al has to do with the quality, not so much as where you spend your money..
