Description

Overview

Carrier Transicold Water Pump Kubota V2203 is an engine water pump assembly for compatible Carrier Vector units using the Kubota V2203 platform in the CT4-134 family. It circulates coolant through the engine and heat exchanger circuit to maintain operating temperature and support normal unit performance.

Check the engine and unit identification before ordering, as this pump suits Tier 1 to early Tier 2 builds. If the existing pump shows shaft leakage, bearing noise or poor coolant flow, replace it and inspect belt tension and coolant condition at the same time.

Features

• Engine water pump assembly for Kubota V2203 based Carrier applications
• Restores coolant circulation when the original pump is worn or leaking
• Suits Carrier Vector units using Tier 1 to early Tier 2 engine builds
• Part of the engine cooling system on CT4-134 family platforms

Specifications and Materials

Part number: CA-25-37581-10-AM.

Use the Carrier Transicold V2203 engine service parts list to check water pump placement and related cooling components.

Compatibility and Fitment

Match the engine build and pulley setup before ordering, as Carrier used more than one cooling arrangement across Vector generations. When fitting the pump, clean the gasket faces, tighten fasteners evenly, and bleed air from the cooling system after refill.
