It looks very easy, just unscrew and put new ones in, right?

Is there a set lifespan or replacement interval?

They can be lifespan items, but they do wear out.

If it's cold and you can start your car, then they should be fine. If you have trouble starting your car, try extending the glow plug duration. Just unscrew and replace. Try to use anti-seize.

And of course, the best way to warm your block is with a coolant heater!

Well it couldn't hurt, but if there's nothing wrong then just leave it alone for now.

Just unscrew and put back. Make sure the area around the hole is clean, torque is pretty light.

Be careful not to bang the glow plugs. I read that the newer engines use a ceramic glow plug and it can break off if it get damaged. This will cause engine damage.
