A frozen engine usually means that some component, like the engine block or a cylinder head, has cracked due to water expanding as it freezes. This is most likely to happen if the coolant wasn't properly winterized. The severity depends on how extensively the component cracked.
Here's a breakdown:
* Minor Crack: A small crack might be repairable through welding or other methods. The cost will vary widely depending on the specific engine and the location of the crack.
* Major Crack: A large crack or multiple cracks will likely require a complete engine replacement or at least a major rebuild. This can be incredibly expensive, potentially exceeding the car's value.
In short: A frozen engine is a very serious issue. You need to have a qualified mechanic assess the damage. The decision of whether to repair or scrap the car will depend on the extent of the damage and the cost of repair compared to the value of the vehicle.
