Engine replacement vs head gasket repair cost
A blown head gasket can cost around $1,500 to fix, but severe overheating damage may require a full engine swap jumping the bill closer to $5,000. Deciding between the two depends on whether the underlying block is warped or damaged, forcing car owners to weigh a costly repair against a total replacement before committing funds.

“So at this point, engine swap, or HG replacement?”source ↗
“I just want to go in eyes wide open. With what I shared, what percentage is it that the engine needs repair in addition to radiator. That will move it from $1500 repair to almost $5k repair so I need to make a decision now.”source ↗
