It’s not a hard job to DIY. Biggest pain is removing the crank pulley to get to the last bolt, but even that isn’t too bad. If I remember right, remove the intake tubes, electric radiator fan, belt, disconnect hoses, and remove crank pulley... then replacing the pump is pretty quick.

Also recommend thermostat and hoses if they haven’t been replaced yet.
