2000 Cherokee XJ 4.0L water pump: 6 bolts, 11 qt coolant
The 4.0L Power Tech I6 in the XJ uses an iron-body water pump with a stamped steel impeller, mounted with six bolts to the timing chain cover. The pump shaft is sealed with a conventional packed bearing and ceramic seal.
OEM water pump: Mopar 5012366AA or Gates 43026 — iron body, clockwise rotation, 5/8" pilot shaft, includes new gasket
Mounting bolts: (6) 3/8"-16 x 1-1/4" hex head bolts arranged in a circle around the hub — torque to 30 ft-lb in a star pattern to seal the gasket evenly
Gasket: Use Fel-Pro 35373 or OEM paper gasket with a thin coat of Permatex Aviation Form-A-Gasket No. 3 on both sides — do NOT use RTV silicone as it squeezes into the coolant passages
Coolant capacity: 11 quarts total (2.75 gallons) for the 4.0L with heater core — drain at the radiator petcock and the block drain (3/8" NPT on driver side of block) for complete replacement
Fan clutch removal: The fan clutch nut is 36mm and has reverse (left-hand) threads — use a 36mm wrench and a hammer to loosen; the clutch must be removed to access the pump pulley bolts
Pulley bolts: (4) 1/2"-20 x 3/4" bolts hold the pulley to the hub, torque to 20 ft-lb — hold the pulley with a strap wrench to prevent rotation

- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
What the Pros Prefer: 2000 Jeep Cherokee Water Pump Workflow
Controlled coolant capture, mating surface prep, and cooling system purging.
Pulley Bolt Pre-Loosening & Coolant Drain
Shop Tip:Loosen the water pump pulley mounting bolts 1 turn while the serpentine belt is still under full tension. The belt grip prevents the pulley from spinning freely in your hand.
Pump Extraction & Catch Pan Placement
Shop Tip:Place your drain bucket directly beneath the pump before unbolting. Significant trapped coolant remains behind the pump cavity even after draining the radiator.
Mating Surface Decontamination
Shop Tip:Scrape all residual paper and dried RTV until the aluminum surface is clean, smooth, and dry. Wipe with brake cleaner so the new gasket bonds flat.
Torque Pattern & Air Bleed Funnel
Shop Tip:Small M6 and M8 water pump bolts have low torque ratings (7–15 lb-ft). Overtightening snaps bolts in the block. Use a spill-free funnel to purge air pockets on refill.
