2D project - player respawn delay problem

Hello there! I making some simple 2D side-scroller. Because I'm noob in programming, all my C# scripts for small systems are based on GamesPlusJames tutorials (youtube). Problem starts when I want to add some delay and make my player to dissappear.

Gamesplusjames had only one sprite renderer attach to player/character (etc) object, but my player is build with more sprites in more separate objects. The main problem is "character.renderer.enabled". Any ideas what I've should type instead?

 public void RespawnCharacter()
      {
                  StartCoroutine ("RespawnCharacterCo");
          }
  
      public IEnumerator RespawnCharacterCo()
      {
          Instantiate (deathParticle, character.transform.position, character.transform.rotation);
          character.enabled = false;
          character.renderer.enabled = false;
          ScoreManager.AddPoints(-pointPenaltyOnDeath);
          Debug.Log ("Character Respawn");
          yield return new WaitForSeconds (respawnDelay);
          character.transform.position = currentCheckpoint.transform.position;
          character.enabled = true;
          character.renderer.enabled = true;
          Instantiate (respawnParticle, currentCheckpoint.transform.position, currentCheckpoint.transform.rotation);
      }
