Product Overview

The water pump circulates coolant through the engine and radiator. Leakage from the vent area, bearing noise, shaft play, overheating, or visible coolant loss around the pump are common reasons to inspect or replace this component.

Carrier references 25-34935-00 / 253493500 for this pump family, and refrigeration-parts catalogs associate it with Supra 4XX/5XX units and the CT2.29 engine. The pump is supplied for engine cooling, not the refrigeration refrigerant circuit.

Key Features & Performance

  • Cooling-system circulation: Restores coolant flow through the engine when the original pump is leaking or mechanically worn.
  • Application-specific mounting: Designed around the matching engine's mounting face, hub/pulley arrangement, and hose connections.
  • Service repair: A practical repair point when pump bearing or seal wear is confirmed rather than replacing unrelated cooling components.

Part Numbers & Specifications

  • Carrier Reference: 253493500
  • Alternate Reference: 25-34935-00 / 25-34935-00SV
  • Related Reference: 29-70052-00 on applicable catalogs
  • Component: Engine coolant water pump

Before You Order

Confirm the refrigeration-unit model, engine tag and original pump number. Compare the hub/pulley and mounting before transferring accessories from the old pump.
