's alright, I understand that many of these things are at my own risk. I'm all for hyper-insulating my engine, but the difference between a 99% and 100% grille block is the difference between not warming up and borderline overheating, even at those temperatures. The Insight has a water jacket in the exhaust manifold and so has larger heat dissipation requirements than you'd expect from a 1L engine, so removing the radiator and relying on the heatercore alone is not something I'm keen to do.
