  1. You'd recover more energy from spinning a turbine with exhaust gas.

  2.  @kevinrusch3627  I'm not really optimistic due to the Stirling's low power to weight ratio. Essentially having a Stirling using the hot coolant coming off the engine would probably not eliminate the radiator unless you were hauling multiple Stirlings in tandem, and there's so much mass and area it actually ends up cooling the fluid. Just the fact that the radiator is still needed to actually cool the liquid properly before it's pumped into the engine again means most energy is still wasted towards the atmosphere. If I'm not mistaken there's cars that do use engine heat to provide cabin heat, which skips the losses in efficiency. In terms of exhaust, I don't think the exhaust would be well used with the coolant (you don't want to re-heat the coolant nor cool the exhaust) so that would mean another Stirling being hauled.
