Engine stops when hot

reg codes only work in UK, use real years..... so ROTW can tell.
please, tell what it does good and bad driving, idling , parked, moviing
hot and cold engine, full power from engine on hills.
stalling (it stalls) but when does it stall, under what conditions. hot or cold engine. only at stop lights hot. or>????
when an engine is cold the RPM is very high (iAC device) and it will not stall cold , if it does that is key.
if it never stalls hot. and runs perfect hot say so.
all these, clues build evidence. to what is wrong.
then we do tests.
PS: ever think to get that 60,000 mile (100km) tuneup>> now be it.

no year stated.
no engine stated, "size"
running 0w oil in an old engine?
what i do us use a real oil pressure gauge to see truth.
the dash gauge is just a crude warning. nice but not instrument grade.
and all gauges, do that on a hot engine,
but not 5psi, my cars run 20psi min. hot...
what engine, what miles on it, what year.
all unknown.

does the temperature gauge show engine is very hot? could be a stuck thermostat, did you check for engine codes? this can be checked for free at most chain auto stores and give you insights into the problem.

check oil level add if low.. check antifreeze level add if low..retest

some vehicles have their thermo fans set on a hot wire, unfortunately when you stop your engine, you stop water flow, after a long drive your engine is hot, turn off your engine, water flow stops, engine transfers more heat from the block, coolant heats up, fans turn on to cool the motor,(the motor only knows that the temprature has gone up

When you stop the engine heat is still being generated inthe engine from all the hot bits. As there is now no water circulation through the radiator these cause local boiling which pushes the watemp right up. The pressure generated by this rise in temperature opens the cap expelling water. I would find the cause of the engine running hot to start with. Faulty fan /fan motor,failed viscous fan hub, thermostat blocked radiator are a few starting points

Have you had the electronics tested for fault codes? That is the 1st step when you have a problem like this.

may be your water pump or a hose, or your radiators broke i recomend not to run it is not a good idea or youll blown the head gasket or worst, have it check and fixed

SOUND LIKE FAULTY IDLE SPEED CONTROL OR FAULTY FUEL INJECTOR OR A INTAKE VACUUM LEAK.IF GETTING HOT WHILE STOPPING.CHECK COOLANT FAN FUSE AND RELAY.IF BOTH GOOD.HOT WIRE COOLING FAN TO CAR BATTERY USING JUMPER WIRES.IF COOLING FAN DONT WORK REPLACE THE MOTOR.IF FAN WORKS.COOLANT TEMPERATURE SENSOR IS BAD.ALSO HAVE CAR SCANNED TO SEE WHAT CAUSING CHECK ENGINE LIGHT TO COME ON.

sounds to me like the thermostat may be stuck. i would check the coolant, fan, and belts.
