Product Overview
The Aeroflow AF64-4111 billet aluminium oil thermostat is designed to control engine oil temperature in external oil cooler systems. It retains oil until operating temperature is reached, then opens to direct flow through the cooler for stable, consistent lubrication performance.
Key Features
- Billet 6061 aluminium construction for strength and durability
- Black anodised finish for corrosion resistance and a clean appearance
- Thermostat fully open at approximately 82°C (180°F)
- Four labelled -10AN ORB ports for plumbing to and from sandwich adapter and oil cooler
- Two 1/8" NPT ports with plugs supplied for auxiliary oil temperature or pressure sensors
- Self-adjusting flow according to oil temperature, similar to a coolant thermostat
Function & Benefits
- Helps engine oil reach operating temperature faster by bypassing the cooler when cold
- Directs oil through the cooler once the thermostat opens to prevent overheating
- Maintains more stable oil temperature for improved engine protection under load
- Compact billet body suits performance and motorsport oil cooler installations
Installation Notes
- Requires a suitable sandwich plate adapter or block adapter on the engine to route lines to the external oil cooler
- Compatible with accessories such as AF64-2108 oil cooler sandwich plate and AF64-2060 sandwich adapter
- Use appropriate -10AN ORB fittings and quality oil hose for all connections
- Ensure correct orientation of labelled inlet and outlet ports during installation
