Mounting the Oil Cooler

How to Install the Oil to Water Cooler on Brz

Locate a suitable spot on the front of the engine bay where you can mount the oil cooler. The ideal location should provide good airflow and be close to the oil filter.
Use the mounting brackets and hardware included in the oil cooler kit to securely attach the cooler to the chosen location. Ensure the cooler is level and firmly in place.

Drilling and Tapping the Oil Filter Housing

Determine the exact location on the oil filter housing where you’ll need to drill and tap a hole to accommodate the oil cooler lines. Measure and mark the spot carefully to ensure proper alignment.
Using a 1/8-inch drill bit, carefully drill a hole in the oil filter housing. Be cautious not to damage any surrounding components.
Using a 1/8-27 NPT tap, thread the hole to match the size and pitch of the fittings provided with your oil cooler kit.

Connecting the Oil Cooler Lines

Attach the oil cooler inlet and outlet lines to the fittings on the oil filter housing and the oil cooler using the provided hardware.
Ensure all connections are tight and secure to prevent any leaks.
Route the hoses carefully, avoiding sharp edges or moving components that could potentially damage the lines.

Filling the Oil Cooler

Before starting the engine, fill the oil cooler with the recommended type and quantity of engine oil, as specified by the oil cooler manufacturer.
Refer to the oil cooler kit’s instructions for the exact oil capacity and type to use.

Testing the Installation

Start the engine and let it run for a few minutes to allow the oil to circulate through the cooler.
Carefully inspect the entire installation for any signs of leaks or issues.
Check the engine’s oil pressure to ensure it’s within the normal operating range.
