Land Rover is an iconic British company and creator of the second oldest four-wheel drive vehicle in the world, the Land Rover. The LR3 (Discovery 3), produced from 2004 to 2009 is the third generation of this mid-sized SUV. As much as Land Rover owners love this luxury sports utility vehicle, certain problems do arise with them.
One issue that LR3 drivers have experienced is a problem with a coolant leak under the intake manifold. A small coolant leak may be coming from the bleeder hose located under the intake manifold. This is not an uncommon problem and it should be a relatively easy thing to have a mechanic fix. The entire manifold should not require removal, but just the throttle body.
This is something that you may be able to do yourself if you are mechanically inclined, but it depends on the severity of the problem. If it is simply an issue of the bleeder hose failing, then replacing a small part like the brass straight might fix the problem. This part can be purchased at an auto shop. However, this might be more trouble than it is worth, especially if you are unfamiliar with auto repair.
The best course of action to take if you are experiencing a coolant leak is to bring your Land Rover Discovery 3 in to your local Land Rover service expert for an inspection. They will be able to give you an estimate of the repair costs and will probably save you money over a dealership.
Search for a local, independent Land Rover repair shop with Land Rover mechanics that have dealer-level expertise at a fraction of the expense.
