1997 Toyota Tacoma Water Pump: 3RZ-FE or 5VZ-FE Fitment
The first-generation Tacoma (1995.5–2004) mounts its water pump to the front timing chain cover. The 2.7L 3RZ-FE and 3.4L 5VZ-FE use different pumps with unique pulley diameters and bolt patterns — engine verification is essential before ordering.
2.7L pump: Aisin WPT-038 or Toyota 16100-79125 with 6 bolts and a stamped steel 6-rib pulley
3.4L pump: Aisin WPT-039 or Toyota 16100-69255 with 8 bolts and a larger cast pulley for the 5VZ-FE
Bolt sizes: 10mm × 30mm and 12mm × 35mm flange bolts — torque to 14 ft-lb (10mm) and 22 ft-lb (12mm)
Gasket: Paper gasket with FIPG (Toyota 00295-00103) at the corners — no dry gasket installation
Fan clutch: 10mm hex on clutch hub; hold the water pump pulley with a strap wrench while loosening
Coolant capacity: 9.5 quarts (3RZ-FE) or 10.1 quarts (5VZ-FE); use Toyota Red Long-Life or equivalent
Tip: The 3RZ-FE timing chain cover gasket often tears at the pump flange — inspect and replace the cover gasket as a set

- • 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: 1997 Toyota Tacoma 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.
