It could be several things:
Let's start with a few easy checks:
- Level of coolant: check your level of coolant in both the recovery tank and the radiator (engine cold!) If the recovery tank is part of your cooling system, meaning if your recovery tank is under pressure, just check the level in it and don't worry about the radiator. The coolant should be between the two marks (low/high or cold/hot). In the radiator, the coolant should be almost at the top. A low level of coolant will result in your heat not working in the car, and eventually engine overheating.
- Check for leaks: Do you have a puddle of coolant on the ground underneath your car? With car on, are your water pump/hoses/radiator leaking?
- Thermostat: turn your car on and let it reach normal operating temperature. When the temp gauge reaches normal temp, grab the upper radiator hose with your hand. It should be warm and get very hot quickly (as the hot coolant exit your engine on its way back to your radiator). If the upper hose remains cold/luke warm and the temp gauge keeps rising, you need a new thermostat. Something else you can check while you're at it: when your car starts overheating, do your cooling fans come on? If not there's a problem there too.
For your car to overheat so quickly, chances are your thermostat is the problem. It's not an expensive fix. Good luck
