My Golf, which I only use for the occasional forray, is putting water out the expansion bottle. I took it for a spin today, topped up the expansion bottle before I left and noticed it had spat some coolant out when I got home.
The car did reach operating temperature, I think, but the top hose of the rad was hot while the bottom hose was stone cold. (Meaning the bottom of the rad was cold and the fan switch(new) wouldn't activate),
The water pump has 3 hoses connected
1 was cold (the same one connected to bottom of the rad.
2 others were hot.
Is there any particular blockage which would cause a malfuntion?
There doesn't appear to be any leak on the water pump, and no strange noises, so I assume it's ok.
The Heater blows very hot. Would that rule out the thermostat being dodgy?
