My 1993 dodge shadow overheats and the coolant just dissapears
Every time I get in my car I have to add more collant and water. It doesn't leak as far as I can tell. I did notice one time when I was adding more flueds that the reserve tank was over filled. The funny thing is that 5 miles before when I added my fuleds before I left it was in between the low and Max. . . the car was over heating at the time. Do you know what is wrong?I didn't leave the car for a second so no one could have over filled it where did the fluid come from and is that why it over heats??

Sounds to me like a blockage in ur pipes. its not uncommon for thermostat/ water pumps to rust out and cause problems. I would remove the return hose from radiator at home, run a hose into ratiator and flush. start motor for a minute or two and make sure you are getting flow through.

A lot depends on where the leak originated. If it's the water pump, it will only get worse, circulation will be impaired, engine can easily overheat...won't ;last long.
If it's an external leak, and you don't let the coolant get too low, it can go a l;ong time, with daily or regular topping up of the radiator.
If it's a blown head gasket and leaking internally, its days are definitely numbered. If its a head gasket and leaking externally, a little safer, but iffy: the head gasket may keep eroding and the leak get bigger. Overheating of the engine may occur.
SOUND LIKE ENGINE COOLANT LEVEL LOW.CHECK COOLANT SURGE TANK.IF LOW MORE LIKELY RADIATOR COOLANT LEVEL LOW.ADD COOLANT TO COOLANT SURGE TANK UNTIL COOLANT LEVEL STAY AT FULL COLD MARK DONT OVERFILL OVERFLOW JUG.
If you have to add water everytime that means you have a leak in the cooling system.If your cooling system is in propor order you should never have to add water.As far as where it is actually leaking from is very hard to say.There are several components that can leak coolant.If you are getting low on coolant far enough that will cause your truck to overheat.
Is the reserve tank cracked or have a deteriorated hose going to the radiator? Remove the tank to find out. A bad seal on the radiator cap can also lose fluid. A coolant leak anywhere can deplete the coolant level in the radiator and reserve tank. Check your owners manual for antifreeze type and mix ratio with water.
check your coolant and oil. if the coolant is chunky (this can happen if it's been in there a very long time) try draining it and flushing it. obviously replace the oil if it's dirty/low. these cars do have some minor problems with leaking valve cover gaskets.
if your coolant is extremely low compared to where you last left it check for leaks. cranking the heat up to high and blasting the fans will usually help you spot them.
if all of these things are fine try replacing the thermostat, they're about $4-12 depending which one you get and very easy to replace. don't forget the gasket for it. the old one's probably melted if it's been in there a while.
****note: any time the coolant is emptied/ replaced you need to bleed the block or it will continue to overheat. it's bolt above where you install the thermostat and where the coolant goes in and out of the block. it uses an allen wrench and can be hard to unstick without a torque wrench allen. be sure to leave it open until coolant starts to leak out, and not to cross thread when retightening.****
