Jaguar XF Coolant Leak Diagnosis - The Dreaded Plastic Housing

In today's episode of Projects in the Barn, things haven't quite gone to plan with the new Jaguar XF project. After successfully passing its MOT, I took the car for its first real test drive to Dorchester, but it didn't take long for that unmistakable smell of burning coolant to start coming through the vents. ​Upon getting the Jag back to the barn and popping the bonnet, I've discovered a persistent drip coming from a plastic housing right in the "V" of the engine. It looks like the thermostat/coolant outlet housing has failed—a very common issue on these Jaguar and Land Rover V6 diesel engines. ​In this video: ​First drive impressions after the MOT. ​Troubleshooting the "Low Coolant Level" warning. ​Visualizing the leak: See exactly where it's dripping in the engine valley. ​Next steps for the repair and what parts I'll be ordering. ​If you're a Jaguar XF owner and you can smell coolant or notice your levels dropping, this video might help you pinpoint the source of the problem before it leads to overheating. ​Subscribe to follow the full repair process and the rest of the XF restoration! ​#JaguarXF #JaguarRepair #CoolantLeak #CarRestoration #JaguarXF27 #DIYRepair #ProjectsInTheBarn #JaguarOwners #ModernClassic ​3.
