Question:
It is a 1989 Lincoln continental, it was really low on coolant I added coolant then started car and turned heater on so that i could add more but, did not seem to need much more. Took it for a drive and engine started heating up and heater blows cold air. Any suggestion?

My car, upon slowing, stops with a jerking motion, will a tune-up fix this?
Same thing happened to me in a Taurus. It turned out that there was a bubble of air trapped somewhere in the cooling system and that was sort of "vapor locking" the flow of coolant. No flow, no cooling, so for years the engine would frequently overheat, but no flow also means nothing going to the heater core so the air blowing through that stayed cold. I had a pressure flush on the coolant which removed the air bubble and I haven't had the problem for 3 years now. One other possibility -- if your antifreeze/water mixture isn't where it should be, you can get a bit of ice that can block the flow of coolant and produce the same symptoms. That melts fairly quickly though and things will very suddenly go back to normal (until the next really cold day).the check engine light on my 2005 dodge ram has come on?
bad thermostat.maybe your thermostat is not working properly...put in a new one....
Why wont my car start in the cold?
.Your thermostat is bad. This is a a minor repair job, and if you are mechanically inclined you can fix it yourselfWill extra low sulfer diesel fuel have any adverse effects on old(76-80) diesel engines?
Your heater core may be blocked. If flushing the system doesn't do the trick, then you'll have to replace it.edited to add: I'm thinking zebras instead of horses. The thermostat is a very good first step. Try that first.
change the thermostat and flush raid. add new coolant to fix,,

Have the thermostat checked.How can I get rid of squeeks with no grease fittings?
Providing the heater was working ok previous to the coolant level going low there is a strong possibility you have an air lock in the system and therefore no coolant circulation through the heater core. Also pay attention to the coolant shut of valve . These only pertain providing the thermostat is ok. With a bad thermostat you should at least get a little heat. BobWhen you say the engine is getting hot, do you mean hot as in running hot, or hot as in reaching operating temperature? If the engine is running hot I would say change the thermostat. If it is not running hot then the valve that controls the water to the heater coil is not opening.
