I was looking through the vehicle mods again and I started thinking: given the way most of us drive, would a smaller radiator help FE? A lower overall volume of water and smaller radiator surface area should improve warm-up times. Additionally, a shorter water path should decrease the back pressure on the water pump, meaning less power is required to pump the same volume of water.

The downside is obvious. We could increase the risk of overheating. So I'm not suggesting cutting the radiator size in half. It is also more likely that your fan will kick on more often.

What are your thoughts?
