I have a 99 Disco II, which I replaced the thermostat on in July due to my mechanic saying it was "sticking" causing it to overheat, that ia overheating yet again! Any suggestions? I can't drive more than 3 miles without the red light beaming! So hear it sits in my driveway!   Alen Babayan (Alen) Member Username: Alen Post Number: 53 Registered: 11-2002 Posted on Monday, September 29, 2003 - 08:19 am:    Did u ever take it offroading in muddy waters? If so, run high pressure water about three feet from the grill and see if mud comes out.   Carrie (Cgahrville1) New Member Username: Cgahrville1 Post Number: 7 Registered: 07-2003 Posted on Monday, September 29, 2003 - 06:25 pm:    I haven't been off roading (yet). I purchased my Disco used back in April.   jay michaels (Disco99ii) New Member Username: Disco99ii Post Number: 5 Registered: 07-2003 Posted on Monday, September 29, 2003 - 07:16 pm:    carrie, go to www.atlanticbritish.com-click on discovery-then look for TECH TIPS on the menu on the left side of the page--then go to overheating-- skip the thermostat part-you've already changed it- good luck   Chris Browne (Chris_browne) Senior Member Username: Chris_browne Post Number: 356 Registered: 02-2003 Posted on Monday, September 29, 2003 - 07:34 pm:    This one doesn't make much sense Open hood, with engine off and key out of the ignition, remove the top of the fan shroud an see if there is mud, signs of antifreeze leaks etc on the radiator. Those early d2 radiators were junk quality Are you using any coolant? Check too for leaks This overheating happens so fast I'm almost wondering whether the sensor is bad Is the viscous coupling working?
