Confirming the Correct Replacement
The OE number is useful but not sufficient on vehicles with multiple cooling packages. For MITSUBISHI Delica, cross-check 31248-70302, 31146-00301, engine configuration, fan diameter, center mount and surrounding shroud dimensions.
Service Symptoms and Related Checks
Reduced low-speed cooling can have several causes, including a weak clutch, blocked radiator, damaged shroud or incorrect fan blade. Confirm airflow direction and system condition instead of replacing parts by appearance alone.
Why Blade Condition Matters
31248-70302 is a mechanical airflow part intended to complement the radiator, fan shroud and drive mechanism. Incorrect offset or rotation may reduce airflow or create contact, which is why dimensional confirmation is part of the ordering process.
Damage and Balance Screening
The acceptance process should confirm that the blade rotates without visible wobble once correctly mounted. Any contact with the shroud, radiator or hose requires the installation to be stopped and rechecked.
Parts Enquiry Requirements
Sample approval is recommended before a large replacement program. After 31248-70302 is confirmed, keep the approved OE/SKU and measurement sheet as the reference for repeat orders.
Frequently Asked Questions
When should 31248-70302 be considered for replacement?
Inspect the fan after cracks, missing material, wobble, abnormal noise, contact marks or cooling complaints are found.
Can a new blade solve every overheating problem?
No. The radiator, thermostat, coolant circuit, shroud and fan drive must also be diagnosed.
Why is hub concentricity important?
The blade should rotate around the intended center without visible wobble, reducing vibration and clearance risk.
What should be checked after installation?
Rotate the assembly by hand, verify shroud and radiator clearance, secure the mounting and confirm there is no contact.
How is a mixed-OE enquiry prepared?
List each OE and SKU on a separate line with quantity, vehicle data and destination to avoid product-matching errors.
