🔧 XT5 - Water Pump Replacement

On your XT5, the water pump circulates coolant through the engine and radiator. Replacing it involves draining coolant, removing the drive belt and a few front-engine components, then installing the new pump and refilling/bleeding the cooling system.

Difficulty Level: Advanced | Estimated Time: 3-5 hours


⚠️ Safety & Precautions

  • ⚠️ Let the engine cool fully before opening the coolant reservoir.
  • ⚠️ Support the vehicle securely on jack stands before working underneath.
  • ⚠️ Coolant is toxic—use a drain pan and clean spills immediately.
  • ⚠️ Keep hands/tools clear of the belt path when releasing belt tension.
  • ⚠️ Battery disconnect is recommended if you’ll be working near the starter/alternator wiring.

🔧 Required Tools

You'll need the following tools for this repair:

  • Floor jack (rated 3-ton minimum)
  • Jack stands (rated 3-ton minimum)
  • Wheel chocks
  • Safety glasses
  • Nitrile gloves
  • Drain pan (at least 3-gallon)
  • Funnel
  • 3/8" drive ratchet
  • 1/2" drive ratchet
  • Socket set (8mm-18mm)
  • Extension set (3" and 6")
  • Torque wrench (10-150 ft-lbs range)
  • Serpentine belt tool (specialty)
  • Trim clip removal tool
  • Flat-blade screwdriver
  • Pliers
  • Shop towels

🔩 Required Parts

  • Dex-Cool coolant (premixed 50/50) - Qty: 2-3 gallons
  • Serpentine belt - Qty: 1
  • Hose clamp assortment - Qty: 1

📋 Before You Begin

  • Park on level ground, set the parking brake, and chock the rear wheels.
  • Let the engine cool completely (ideally overnight).
  • Plan to capture and properly dispose of old coolant.
  • If disconnecting the battery: use a 10mm socket to remove the negative terminal and isolate it so it can’t spring back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I give you the exact bolt locations and torque specs for your XT5, I need 2 quick details:

  • Is your XT5 FWD or AWD?
  • Are you replacing the pump due to a leak or due to an overheating issue?

Those two answers change the best access path and checks.


✅ After Repair

  • After refill/bleed, verify the heater blows hot and the engine temperature stays steady.
  • Recheck coolant level after the first full heat cycle and top off as needed.
  • Inspect for leaks around the pump and hoses with the engine running.

💰 DIY vs Shop Cost

Shop Cost: $850-$1,400 (parts + labor)

DIY Cost: $180-$450 (parts only)

You Save: $670-$950 by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 3-5 hours.
