Installation
Difficulty: Intermediate | Time: 45–90 minutes
-
Disconnect battery negative terminal and allow the cooling system to depressurize (wait 30 minutes after engine shutdown).
-
Drain transmission fluid by removing the sump plug. Capture old fluid in a container for proper disposal.
-
Locate the transmission cooler in the lower front or side of the vehicle (location varies by model; consult your service manual).
-
Disconnect brake hose unions and transmission fluid feed/return lines. Plug lines immediately to prevent air ingress.
-
Remove mounting bolts (typically 2–4 points) securing the old cooler to the chassis or radiator support.
-
Install new cooler in reverse order, ensuring hoses are routed without kinks or pinches and connectors are fully seated.
-
Refill transmission fluid to factory specification (refer to your gearbox oil type; typically Jaguar/Land Rover approved automatic fluid).
-
Reconnect battery, start engine, and check for leaks while the transmission cycles through gears. Allow 10 minutes idle time.
-
Road-test at moderate speeds (15–30 mph) for 5 minutes to circulate fluid and verify smooth shifting. Recheck fluid level after cooling.
⚠️ Important: Transmission fluid is highly flammable. Never work on a hot engine or cooling system. If you're not confident with this task, we recommend professional fitting by a Land Rover-specialist technician. Labour typically costs £200–400 at independent workshops.
