Q1: Is this water pump a direct replacement for my Doosan DH225-7 excavator?
A: Yes, this pump (part numbers 65.06500-6124D and 65.06500-6142) is designed as a direct OEM replacement for the Doosan DE12 and DE12TIS engines found in DH220-3, DH225-7, and DH370-7 models.

Q2: What maintenance should I perform when replacing the water pump?
A: We recommend replacing the coolant, thermostat, and all associated gaskets and seals simultaneously. Flush the cooling system thoroughly before installing the new pump to remove debris and old coolant residue. Check the fan belt and tensioner for wear, as a slipping belt can reduce pump efficiency and cause overheating.

A: While this pump fits DE12 and DE12TIS engines generally, minor design variations may exist across production years. Please provide your engine serial number or machine VIN to our sales team for a final compatibility check.
