I have a 2006 v6 ford mustang and just developed this problem yesterday.
When I drive the car, the temp guage stay right in the middle, but when I park I get white smoke come from under the hood. I popped the hood and saw coolant leaking from where the top radiator hose meets the engine block. This was producing the smoke. When I checked the hoses, the top hose was hot and hard, the bottom hose was cool and soft.
- I did not touch the radiator to see if there were cool or warm spots
- The overflow bottle looked empty or close to it, but the engine was still hot from driving to work
Thinking this could be one of the following
- bad thermostat
- clogged radiator
- Air bubble somewhere blocking the coolant flow
What do you think the problem is?
