I was poking around the car tonight and noticed that the lower radiator hose was cold. The upper one was hot and the car had been running for a little. So I figure that its either the thermostat or I thought I heard something about bleeding the system. Has anyone done this or have any ideas on this procedure or am I mistaken??
p.s. there is plenty of coolant in the engine!!!
Thanks
