Not sure Rainsey, I'm for from mechanically minded, but do believe new cars that have thermo's work the same way. See you point, with not cooling the block when switched off. I guess at least if it starts 2 get hot, you can switch it off and have the fans running cooling the radiator before is pops the cap and looses coolant
