Question about Lincoln Cars & Trucks
In cold weather, the heater will blow cold until car warms up. I was sitting for 10 minutes idling and noticed the temperature gauge jumping up toward "Hot". When I began driving, the temp came down to normal. I also noticed an odor of antifreeze. I suspect a leak and hoses are due to be changed, But can I have another issue, like the thermostat, water heater, or core? Should I change any of these parts when I change the hoses, belt, and anti-freeze? I remember the old Lincolns were notorious for heater core problems.

unless you got visable signs of leakage its not heater core, but it could be pluged with sediment. take off both heater hoses and flush it both ways until it runs clear. you can also mix a little baking soda and water and pour in core and let set for a while and then flush.

try changing the thermostat if thats not it check and see if you have water leaking in the passenger side floor board if so then you need a new heater core

It may just be the way the car works. I have a 2005 Altima and it does the same thing, but just doesn't blow really warm air. Try putting the air on recirculating, that may help a little. If it's still REALLY cold when you are stopped, I would check/replace the thermostat first. If you want to check the thermostat to see if it's working yourself, just remove it, and inspect it while it is cold, then put it in a pot of boiling water for 3 mins, inspect it, if the valve has opened it is okay, if it looks the same (aka valve was open to begin with) it may just be staying open and it should be replaced.
