Blows warm while the engine is cold, and goes cold as the engine warms up.
I have changed coolant and fitted a new thermostat.
I've been told there's a ball-valve that's prone to sticking, and to just replace it with a piece of straight pipe. I don't yet have a manual for the car so I don't know where this valve would be.
Any ideas?
