water leaking from reservoir's cap
Hello friends,
My 1995 140k miles disco is leaking a lot of water from the water reservoir cap. The engine overheats very fast and I need to wait for it to cool down before I add more water to the reservoir. My first reaction was to buy a new cap but I think the head gasket might be the problem. Any advice? At this point I am willing to try anything….
Thanks in advance,
George

If the reservoir is black get a white one if cap leaks buy a new one, are you running g 50/50 mix?
Is the clutch fan working?should roar when hot
Is there debris between read and condenser?
Last time you did the thermostat?
Codes?
Do you have a ultra gauge to see what the actual temp is? Do not go by the factory gauge
Any other coolant leaks? White smoke in exhaust? Coolant in motor oil? Looks like milk

Hi! Thanks for getting back to me. I truly appreciate the help
I do have the black reservoir. I am running 50/50 mix. My fan does get very load when hot. "debris between read and condenser?" Let me check, but I would say no because I take good care of my motor. Last time I changed the Thermostat was about 3 years. I do not have an Ultra gauge, but the temp is very hot. Vapor comes out of the cap. Reservoir makes growling noises? No white smoke from exhaust? no other coolant leaks. I will check for coolant/water in motor oil.
Thanks for the pointer! Will keep you posted.

I will check with old school method for water in the oil.
Thanks,

You can also feel hot rad. To see if there's cool spots
The black reservoir is bad plastic can break/ burst easy get white from newer d1
At this age probly a combination of semi clogged radiator about $200 new on ebay for nice aluminum one direct fit, new thermostat, good flush, newer resivoir and cap
You may have bad hg but these contribute heavily
If the system does not pressurise the coolant boiling temp is lowered some, may want a 180 stat too
Read above is supposed to be rad . Auto correct is pita

I don't know what your experience level is but I'll assume it's not equal to mine because your asking a simple question that an experienced motor head would not. So with that in mind I'll throw you a large bone.......
As you have 140k on it I would go ahead and do a head gasket replacement (and check the liner to deck height) along with update replacements to insure it's sound and will last as long as you want to remain owning it. If your motor was installed with steel head gaskets replace with the same otherwise you will drop compression ratio with a tall composite even after shaving the heads. (3.9's already have a larger cc'd combustion chamber and the heads are spec'd to shave two times without touching valve to piston dome.)
I'll tell you from experience, diving into your motor at this stage of the game will give you all the information you need to keep maintaining it properly. This is my advice and I have 6 years of saving Rover streamlined cinder blocks to prove it.
If you want a good read on what not to do find Savannah Buzz's thread on head gaskets replacement. I'm not picking on SB as he's suggested the same to other members. It was painful for me as head gasket replacement is fairly simple to do (within a weekend) if planned properly.
Good luck and I'll be following along......
