Griffin Small Dual-Pass Fluid Cooler with 9" SPAL Fan
CXU-00002
The Griffin Dual-Pass Fluid Cooler with 9" SPAL Fan is a compact, high-performance cooling solution for transmission fluid, engine oil, differential fluid, and power steering systems. Built from heavy-duty extruded aluminum tube and fin construction, the dual-pass core keeps fluid in contact with the cooler longer to improve heat rejection in demanding off-road, towing, and race applications.
An integrated aluminum fan shroud and high-output 9" SPAL electric fan provide consistent airflow across the cooler core, even during low-speed rock crawling, technical trail use, or extended idle conditions. Two 1/2" NPT female ports allow the inlet and outlet to be configured from either side, making the cooler easier to integrate into custom plumbing layouts.
Includes:
- (1) Griffin Dual-Pass Extruded Aluminum Fluid Cooler
- (1) Integrated Aluminum Fan Shroud
- (1) 9" SPAL Electric Fan
- Mounting Brackets
Note: Fittings, hoses, wiring, relays, thermostatic controls, and fluid adapters are not listed as included.

Fitment Notes:
- Universal fitment for custom fluid cooling systems.
- Verify available mounting space using the complete cooler dimensions, including the fan and brackets.
- Select fittings and hose sizes appropriate for the fluid type, required flow rate, operating temperature, and system pressure.
- Mount the cooler where the fan can receive and discharge air without excessive restriction.
- Keep hoses away from exhaust heat, sharp edges, suspension movement, and driveline components.
- Transmission and engine oil installations may require a thermostat or bypass system depending on operating conditions.
- For dedicated race vehicles, higher-horsepower builds, or sustained severe-load use, a larger race cooler is recommended.
FAQ
Why use a dual-pass fluid cooler?
A dual-pass cooler routes fluid through the core twice before it exits. This increases the amount of time the fluid spends inside the cooler and can improve heat transfer compared with a similarly sized single-pass design.
Why is the integrated fan important?
Airflow through a cooler drops significantly at low vehicle speeds. The integrated SPAL fan keeps air moving across the core while crawling, idling, towing slowly, or working through technical terrain where natural airflow is limited.
What fluids can this cooler handle?
This cooler can be integrated into transmission, engine oil, differential, power steering, and other hydraulic fluid systems, provided the hoses, fittings, seals, and installation method are compatible with the selected fluid and operating pressure.
Why does the aluminum shroud matter?
The shroud helps direct fan airflow across more of the core surface instead of allowing air to bypass the cooler. More even airflow improves the effectiveness of the complete core, especially when the vehicle is moving slowly.
How should the cooler be mounted?
Mount the cooler in a location with adequate clearance around both the inlet and discharge sides of the fan. Avoid placing it directly against a solid panel, and protect it from tire debris, rocks, exhaust heat, and chassis movement.
When should a larger cooler be used?
A larger race cooler is a better choice for sustained high-RPM operation, high-horsepower applications, long-duration racing, heavy towing, or systems that consistently generate more heat than this compact cooler can reject.
Should the fan run continuously?
Fan control depends on the application. Many systems use a thermostatic switch, ECU output, manual switch, or relay-controlled circuit so the fan operates only when fluid temperature requires additional airflow.
