Is It Easy To Pull a Duramax Engine By Myself?

No, You can’t.

You won’t be able to handle the weight of the engine.

But if you need to pull the engine out while replacing, I suggest you must use an instrument like a pully to pull the engine out from your vehicle.

Or go to your dealer or experienced mechanic to replace the engine.

I advise you not to attempt to replace the engine by yourself if you don’t have past experience.

You need to take help from others to pull it out or you need to use special tools to pull the heavy-weight engine.

So, don’t try to pull the engine without a special tool for pulling the engine.
