  • Critical Function: Ensures consistent engine performance, helping to avoid overheating.

Weaknesses

  • Wear and Tear: Over time, seals can degrade, and mechanical components can wear out, leading to leaks or failure.
  • Complexity of Replacement: Depending on accessibility, replacing a water pump can be a challenging task, requiring some mechanical proficiency.

Recognizing Symptoms of Water Pump Failure

Identifying issues with your 1997 Jeep Wrangler water pump early can save you from extensive and costly repairs. Here are some common symptoms to look out for:
