it depends on what you asked for on the job. Usually at my work, a engine wont go out without a radiator service and top tank/replacement, new water pump, hoses, thermostat, filters, plugs, even vac lines if they are required and anything else that looks slightly sus (belts, idlers etc)
But most people dont like it when they get a quote for a engine, and it is 6k where everywhere else quotes 4k, so it depends on what you asked for.

If you ask for a job that isnt too expensive, then expect problems in the future. If you tell them to replace anything that they see fit, then expect a large bill, but better reliability
