Turn your engine over and turn on the A/C on both high and low. Check your cooling fans to make sure they're operating. They are supposed to turn on with the A/C. If they do, you know the cooling fan circuts work so you need to make sure they turn on when the engine reaches temp. After you've reached operating temperature, check your upper radiator hose for flow. Squeeze it and let it go and see if you feel a surge of coolant rush past. You're checking thermostat operation here. If you have never had your cooling system serviced, have your radiator flushed and filled. They may be able to bring any blockage out by the power flush, but your radiator may be partially clogged thus restricting flow. Check the weephole on tour water pump (it may be on the top of the pulley shaft or underneath). If you see water, the seals are wearing out and the pump needs to be replaced. If all these check out, you can rent a Block Tester at Autozone for $25.00 (free loan a tool program, you get the money back when you return the tester) and a lot of test fluid for $8.99 (it will allow you to test multiple times). Remove your radiator cap and put the aspirator (bulb) in the top of the tester after filling it to the line with fluid. Hold this firmly in your radiator cap (you need to remove it before starting the engine). After the engine is within operating temperature, squeeze the aspirator for two minutes and pull air from the coolant into the tester. The fluid will either remain blue or turn to a blue-green, green, or yellow. If the fluid turns color, you have combustion/emissions gases in your coolant and have a bad headgasket or cracked/warped heads or engine block. You can also check for coolant in your oil. With the engine warm, pull out the dipstick and check the oil. If it's a chocolate milk like color and consistency, you probably have a bad head gasket. If all of this comes back as clear, have your cooling system pressure tested by a shop.

Your antifreeze ratio may not be 50/50 (antifreeze/water) and the radiator cap may need to be replaced. The cap should hold 8 lb of pressure but if there is to much water then antifreeze, the coolant will boil over faster but be careful not to have to much antifreeze. Too much antifreeze will gel up and cause over heating. Good luck and hope this helps. Start with the radiator cap replacement and flush out the oil antifreeze and replace with new coolant with a 50/50 mix, you can buy them premixed 50/50 if you not sure how to measure it. The proper amount your car takes is 9.5 liters total fill.

Overflow to water container not functioning model no 2650

This expansion tank is only when coolant builds up so musch temperature and pressure that it needs to release, so it relieves itself from the radiator into the expansion tank.
Then, when coolant returns back to normal operating temperature, the pressurized air contracts, forming a negative pressure or vacuum, sucking the now-cooler coolant mix back in to the radiator and cooling system.
So if your water is not getting to the bottle at all, even when engine is boiling, check the outlet and overflow line for blockages, the stem-valve in the bottle is moving, pressure/water leaks in the cooling system venting water or steam.
Also check radiator cap is correct for the car model and operating.

2008 corsa utility overheating & water is boiling & pushing out through the water bottle

I see two possible causes.
1) Something is blocking air from cooling the radiator. Is there any debris like leaves blocking the radiator?
2) Something is preventing coolant from flowing through the engine. Could be a water pump failure.
Make sure your engine old level is within proper range.

How do you top up water on C1

Water for what? Do you mean engine coolant? If so you top it off at the engine coolant surge tank under the hood, it is a plastic tank with green or red or yellow fluid in it (most common colors of modern coolants), use a 50/50 mixture of coolant and low alkaline water like drinking water from bottles about 90 cents a gallon at the local Safeway or Lucky super market..

Engine Cooling The cooling system components are the:
  • engine coolant temperature sensor (ECT sensor) (12A648)
  • radiator (8005)
  • degas bottle (8A080)
  • radiator draincock (8115)
  • water pump (8501)
  • water temperature indicator sender unit (10884)
  • water thermostat (8575)
  • dual speed fan motor assembly
The water pump circulates the coolant.
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan motor (8C607):
  • operates only when the ignition switch is in the RUN position.
  • will not operate with the switch in the OFF position.
The engine coolant flows:
  • from the lower radiator hose (8286) to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump; an open water thermostat allows the engine coolant to flow to the radiator.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of clean, drinkable water and engine coolant.
To maintain the integrity of the coolant and the cooling system:

I have a coolant system that needs to be bled of air. How would I go about doing that?

A complete drain and refill of the cooling system at 50,000 miles (80, 000km) and afterwards at least every 30,000 miles (48,000 km) or 3 years will remove the accumulated rust, scale and other deposits. The recommended coolant is a 50/50 mixture of ethylene glycol and water for year-round use. Choose a good quality antifreeze with water pump lubricants, rust inhibitors and other corrosion inhibitors, along with acid neutralizers.
  1. Raise the vehicle and support it with jackstands.
  2. Remove the splash shield from the front of the front sub frame and body.

Before opening the radiator petcock, spray it with some penetrating lubricant.
  1. Place a suitable container under the petcock.
  2. Remove the reservoir bottle pressure cap.
  3. Attach a length of rubber hose to the draincock. This will help to direct the coolant flow into the drain pan.
  4. Drain the existing coolant by opening the radiator petcock.
  5. Close the petcock and install the splash shield.
  6. Lower the vehicle.
  7. Determine the capacity of the coolant system, then properly refill the cooling system with a 50/50 mixture of fresh coolant and water, as follows:
    1. Fill the reservoir bottle with coolant until it reaches the top of the cold fill mark on the bottle.
    2. Reinstall the bottle pressure cap.
    3. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air at the A/C vents in the instrument panel.
    4. Start the engine and allow it to idle until hot air is coming from the A/C vents.

  8. If the air discharge from the A/C vents remains cool and the temperature gauge does not move, the engine coolant is low in the engine and must be filled. Turn the engine OFF , allow the engine to cool and add coolant through the reservoir bottle as described earlier and replace the cap.
  9. Start the engine and allow it to idle. Hot air should come from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading within the normal range and the upper radiator hose should feel hot to the touch.
  10. Shut off the engine and allow it to cool.
  11. If available, install a pressure tester and check for leaks. If a pressure tester is not available, run the engine until normal operating temperature is reached (allowing the system to naturally pressurize), then check for leaks.

CAUTION If you are checking for leaks with the system at normal operating temperature, BE EXTREMELY CAREFUL not to touch any moving or hot engine parts. Once the temperature has been reached, shut the engine OFF, and check for leaks around the hose fittings and connections which were removed earlier.
  1. Check the level of protection with an antifreeze/coolant hydrometer
  2. If this is helpful please leave positive feedback.
  3. Thanks, snugglpants

DESCRIPTION AND OPERATION Engine Cooling The cooling system components include the:
  • block heater (optional)
  • cylinder head temperature sensor
  • fan blade, fan motor and fan shroud assembly
  • radiator
  • pressure relief cap
  • degas bottle
  • radiator draincock
  • water pump
  • oil cooler (optional)
  • water thermostat
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for system fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
  • operates only when the engine is running.
  • will not operate when the engine is off.
The engine coolant flows:
  • from the lower radiator hose to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump. An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
  • Alcohol-type antifreeze does not provide adequate water pump lubrication.
    • has lower boiling point
    • reduced antifreeze protection
  • Alkaline brine solutions will cause serious engine cooling system damage.
The cylinder head temperature sensor provides a signal to the temperature gauge.
  • will invoke failsafe cooling.
The optional block heater:
  • electrical heating element is installed in the block cooling jacket.
    • uses a standard 110V (220V in Europe) electrical supply
  • keeps the engine coolant warm during cold weather.
The auxiliary water pump (3.9L only):
  • provides heater coolant flow boost.
  • has a secondary function of providing engine-off cooling.

Sounds like an overheating problem.  My '96 intrepid does the same thing.  When it reaches a certain temperature it kills the engine - not quite total overheating. For me, it turned out to be something in the engine block (minor cracked head or something).  However, you can test and replace the: water pump, coolant sensor, temperature sensor, and the coolant system to make sure there are no blockages or leaks and bleed the system.
