1998 Honda Accord 2.3L F23A1 Water Pump Replacement
The 1998 Accord's 2.3L F23A1 uses a timing-belt-driven water pump tucked behind the front cover. Because the F23A1 is an interference engine, the timing belt must come off — plan to replace both together.
OEM water pump: 19200-PAA-A01; common aftermarket: Aisin WPH-013 or Gates 42029.
Timing belt kit with tensioner: ContiTech TB245K1 or Aisin TKF-003.
Pump mounting bolts torque to 8.7 ft-lb (106 in-lb) — do NOT over-torque into aluminum.
Crankshaft pulley bolt: 181 ft-lb; use a breaker bar and chain wrench or impact.
Timing belt tensioner bolt: 33 ft-lb; verify auto-tensioner pin releases smoothly.
Refill with Honda Genuine Type 2 coolant (OL999-9011) — capacity is 6.2 quarts.
Torque the cam sprocket bolt to 27 ft-lb and confirm timing marks align at TDC.

- • 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: 1998 Honda Accord 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.
