Question: Will letting your car idle for five minutes ruin the engine? Answer: No it won't ruin your engine as long as your cooling system is OK. Cars idle all the time. Think about all the police cars that sit for hours at the scene of emergencies with the engine idleing. Are you asking whether you should idle your car for five minutes to warm it up in the morning? You could, but it wastes gas. You should start the car, let it idle for 30-60 seconds, and then drive slowly and moderately while it warms up.
