Detailed Fitment and Application

DP1390 is a direct-fit cooling system component for vehicles that rely on precise water pump matching to maintain circulation through the engine. The fitment data includes International 4400 and 4400LP from 2004-2016, International 4300 and 4300LP from 2003-2013, International 7300 and 7400 from 2004-2012, and additional coverage for International 3200, 7500, 8500 TranStar, CXT, 3000RE, 3800, 4700, 4700LP, 4800, and Genesis RE. It also covers IC Corporation CE Commercial and CE School Bus models from 2003-2004.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Coolant circulation loss from a worn pump
• Overheating caused by reduced coolant flow
• Leakage at the pump housing or seal area
• Noisy operation from bearing wear
• Service replacement on high-mileage cooling systems

Installation Notes

Verify the mounting style before ordering, especially on applications that note 5-bolt mounting. Confirm the vehicle model and year against the fitment table, since DP1390 is used across multiple International platforms with different mounting notes. Always inspect the cooling system condition during replacement and follow the vehicle service procedure for coolant refill and bleed.

Quality Assurance

Dayco supplies cooling system components for professional repair use, and DP1390 is cataloged for exact application matching across commercial-duty platforms. Confirm fitment by model, year, and mounting note before installation.
