A smart, intelligent and experienced mechanic would have known to replace the cheap but highly needed engine mounts. However, these items are to be discussed as part of any rebuilt engine replacement. You did not mention the year, make, model, engine and transmission and other details of this car. Engine mounts like suspension, electrical work, etc. are all part of a process depending on the age, miles and condition of the vehicle. Much like a house painter can just paint without proper preparation of the surface, it is much wiser and smarter to have the surfaces, if needed, prepared and primed adequately before the last layer of color is applied, the paint.

A good mechanic should factor that into his labor and parts . Original motor mounts may already be compromised , removing and replacing an engine can further damage or compromise the mount and it is the LABOR COST of REMOVING AND REPLACING THE ENGINE not the motor mount itself that is costly.

It is pennywise POUND FOOLISH to install a new engine on an old motor mount( just hoping the engine mount doesn't fail) . If it DOES FAIL , you end up paying to remove and replace the engine TWICE...PLUS a new set of motor mounts anyway. How dumb is that?

Technically, the mechanic could claim that a motor mount failed because it wasn't replaced and "technically" not a required part of the job. On the other hand, you could claim that it failed because of a poor installation job and trauma to it during install/removal . Frankly, that is a "slippery slope" for both of you , and will STILL require more labor and expense.

"Bottom line" ?....replace the mounts . THEN, if they DO fail , the mechanic will have to correct it at HIS expense. Peace.

While replacing engine mounts might be convenient when the engine is out, that isn't always part of replacing the engine. Replace what you need to replace.

No but it is a good time to replace them, while the engine is out.

got a new engine replaced a couple of weeks ago and a few days later the engine mount was broken so would that be the mechanic fault?

Never. Engine mounts cut vibration between the sub-frame and engine.

Nope, sorry, no compo for you. It is up to the vehicle owner to request new engine mounts if getting a new engine,

When replacing an engine do you get a new driver installed too? Sounds like your car needs one that can think!!

No. No peripherals are part of the job. Included would be mounts, radiator, fan, hoses, transmission, A/C components, PS components and so on. These parts must be approved by the owner first. Some stuff is included such as oil and filter.

Nope. That's part of the car, not the engine. Besides, they vary depending on exactly which car body you put the engine in.

No, it's an added cost if the mounts need to be replaced.

Only if they need to be replaced, its not normally part of it

doesnt need replacing unless it broken . that isnt routine maintenance

nope.

no
