"2000 Peugeot 206: Radiator Water Leaks"

Black 2000 Peugeot 206 Front Angle View

I have an 2000 Peugeot 206 and it kept losing radiator water for 2 months. The radiator is clean, changed thermostat, mechanic checked head-gasket by doing some kind of air pressure, there are no leaks at all (did a pressure test), i also changed the coolant reservoir cap. The symptoms are as follow: I drive my car for about 10 minutes, it starts heating beyond 90 degree, water pop out of the container cap (I opened the bonnet and saw water all over the motor), I continue driving the car but it doesn’t overheat (between 90-100 degree), i doubted some failure in water pump or some pressure in the cooling system, the mechanic that I went to for this problem says it may be the radiator valve, I don’t believe it is the issue anyway. Could any one suggest any problems may cause this? I started being obsessed with this and I can’t let it go.

Answer:

Check the following again:
1. bad radiator cap
2. low level of coolant
3. coolant leaks
4. fan malfunctioning
5. clog radiator
6. water pump malfunctioning
7. air trap in your system needs to bleed
There are 2 reasons why you are losing water, there could be a leak or your car is overheating. Hope this help.
