With the engine running open plug on thermostat to bleed system, on the same time pour water into water reservoir for the radiator to keep the water level.

I would recommend that you bleed all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.A heat sensor sending unit which controls activation of the electric fan could also have failed.But is the heat sensor is properly working then check the radiator cap is it properly fitted or got loose.If its loose it will release the pressure and car will overheat.But if the radiator cap is properly closed.Then its time to check the HEAD GASKET.As you have mostly replaced all the possible faults for overheating and if other mentioned possibilities are checked OK.Then its time to check and replace head gasket. Thanks. you can rate this solution and show your appreciation.

I have a 1994 Dodge Ram that keeps overheating.

have you replaced the thermostat , checked for leaks , etc. ? If so, when adding coolant did you bleed the system ? The system has to be bled of air bubbles . Almost all cars have a bleeding screw right at the thermostat housing. It is a regular screwdriver screw. you must bleed the cooling system after adding coolant . If you can't find a bleeding screw, get some thick gloves so you won't burn your hands . Turn the radiator cap until you hear air hiss out. Let it bleed until only coolant wants to come out into the reservoir. The car must be running to operating temperature when you blled the system.

Hi Chamer,

Could be sticking exhaust valves. This sounds like like what you describe and it does rob you of power without generating lots of heat. For Series II Disco's, this is a common problem and requires a valve job to repair. Also can return after every 50,000 miles, depending on how you drive, where you drive and what fuel you purchase. Use the highest Octane you can find (94 at Sunoco). Better for your Disco and the environment too!

Regarding brake work, I use Raybestos on my Series I. No complaints. The series II has wider rotors (lucky you) so you'll have to see if Raybestos carries them. Vented rotors are better - allowing to cool down faster and better stopping ability. If money was a concern, do the brakes yourself! A valve job will run you about $2000US and a complete brake job (at the dealer) will probably be the same. $4000 is too much for me to handle in one bite!

If you do the brakes yourself, expect the following approximate costs: pads $100(fr&bk); rotors $100 each, $15 brake fluid (perform a complete flush); plus your time (0$).

Check around online for the best prices and locations. There are ways of saving and this is one of website I use often:


I found vented rotors for your Disco for $69. Far less than the $300 from your dealer.

Hope i helped.

Alarm goes off intermmitantly when the Disco TDI 300, 1997

First check your battery and connections.There are two alarm units , your dealer will be able to read the fault codes and advise you on what to do.I don't think it's wise to expose the security of your vehicle on line.

Brake failure

Keep reservoir full while you are bleeding brakes. You have probably introduced air at some point.

Start at the furthest, give 2 pumps to pedal only before topping up. If possible - give the job of topping up to a competent helper.

If this resolves the issue, Please rate as Fixya! thanks.
