Suzuki swift 2005 1,3 petrol overheated .coolant fluid was boiling but didn't seem to leak .started the car again drove a couple of miles and the same again.

check to see if the cooling fans at the rad are working. if so then change the thermostat and refill the system. if not then have the head gasket checked for cracking. make sure the coolant is circulating if its not it could be a plugged cooling system or even a water pump impeller problem.

Van keeps shutting off on its own and overheating

you mean the engine, overheats then the engines stalls.?
that latter symptom is normal for overheating.

(some exceptions, ) my Corvette drops cylinders, 1 by 1 to stop
this.(but is still bad , if this happens)

does it overheat only stopped, only moving or both? (KEY question)

fix the over heat, cause. there are may ways to overheat.
from simple to comlex. and no web bunny on earth can guess it.
ill list the simple:
1: low on coolant, no not the side tank, the actual rad is low,
check only on dead cold engine,below 125F (AZ temp)
2: bad RAD cap. not holding pressure.
3: wrong coolant mix or mixing 1 color coolant with another (bad)
4: water pump belt bad , or slipping or missing.
5: rad tubes clogged
6: fan dead,
7: RAD outside ofcore, blocked with filth.
8: blown head gasket,(or far worse)
9: bad water pump.
10: leaks anywhere, (this really is first)

Hi, My 95 2.8 Pajero (turbo deisel) has been overheating. I have replaced the thermostat, water pump and the rad cap (rad replaced 2 years ago) and still it is boiling over into the expansion bottle. When...

Just a guess but I think their diagnosis was that the head and head gasket was not leaking and not a source of the bubbles you spoke of.
Usually when the head or head gasket is leaking, a unusual amount of water will will be expelled from the tail pipe.

Overheating, loss of coolant, reservoir not working

Sounds like to me your mechanic is on the right track by having the rad cap changed. If the coolant becomes low again in the near future and there is no visible fluid leak on outside of engine or on floor/ground then your problem is internal and possibly a head gasket.

I live in central ny Very cold here. My 99 Cherokee over heated guage warning came on and the cooled back down and overheated again. Resivoir was empty, I filled it and drove 40 miles and it was empty...

hi ,trust me you have a leak somewhere ,first fill the radiator/resiviour with water while your engine is running ,when its full and no more air bubbles are coming out ,put the cap on . now keep the jeep running for at least 30 minutes and every 5 minutes check underneath the engine for escaping water .you should spot the leak this way ,if not ,then your head gasket in your engine is probably leaking water into your exhaust and evaporating your water away without being seen ,this would require a large repair by a mechanic.

Sounds like you have coolant leak if you are loosing coolant or a bad thermostat. I would replace the thermostat, they run about $10. The other fan is an aux fan and will only run when the a/c unit is on.

2002 dodge 1500 still overheating

when your engine is hot,check the temperature of your rad,if you get more than 30/50 degrees difference between the top and the bottom of the rad,you need to have your rad professionaly flushed.If you have a digital laser it will out perform any other temperature testing tool.

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy

Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.

2002 Chev Cavalier 2.2L Engine overheating

Did you let engine run from cold after refill, with rad cap off & heater on (not defrost) until the engine reached operating temperature and rad fan came on a few times? If not, try it, you may just have an air lock, provided your sure thermostat is correct one & back in correct way. Rev engine slightly every once in a while and hold it there for approx 10-20 seconds to help burp the air out & increase circulation to heater.
