FAQ

Q1: Is this water pump a direct fit for my Isuzu 4LE1 engine?
A1: Yes, this part (5-87311148-2) is a direct OE replacement designed for the 4LE1 and 4LE2 engine series. It is a bolt-on component with no modifications required, provided your engine uses the EFI system configuration.

Q2: What maintenance is recommended after installing a new water pump?
A2: After installation, we recommend flushing the cooling system to remove old debris and using the correct coolant mixture (typically 50/50 water and ethylene glycol). Check for leaks after the first 50 hours of operation and ensure the drive belt tension is correct.

Q3: How can I verify this part matches my engine before ordering?
A3: Please cross-reference your old water pump’s part number. The most accurate way is to check the casting number on your old pump. If it reads 5-87311148-2, 5-87311148, or 5873111482, this unit is compatible. You can also verify your engine model (4LE1 or 4LE2) stamped on the engine block.
