Question2000 Land Rover Discovery
We are experiencing what sounds like rushing water behind the dashboard of our Disco. Initially, we took it to the dealership for diagnosis and repair. They could not duplicate the problem. The noise appeared on and off until recently when it has become a constant presence. I just returned from a new mechanic I have been going to, to see what he could come up with. He ackowledged the noise but couldn't come up with a definitive solution without pulling off the entire dash. A job he stated should be done at the dealership. So, since I have absolutely no confidence that I will get anywhere with them, I am contacting you for whatever thoughts you might have.
AnswerHi Christian,
Yes, I've heard of this before. It has something to do with the heater hoses located in that area. Its quite possible that you have air in the lines. Have you had work done in that area?
Some owners have complained that swapping the hoses can cause this problem.
Most likely, air was allowed in and that's why you're hearing the coolant slosh around.
Make sure your coolant level is topped up. With the engine cold, fill the reservoir to the top. Start the engine with the reservoir cap off and let the engine warm up. At the same time, turn your heater to the highest heat level and max fan.
Run the engine with an idle speed of about 1500 to 2000 RPMS JUST for a minute or so. Doing this will cause the engine to draw in the needed coolant from the reservoir.
This should fix your water noise problem.
Best of luck,
