Question about 2000 Daewoo Leganza

1 Answer

COLD AIR BLOWING THROUGH HEATER

I have a 2000 Daewoo Leganza. When I first bought it, there was no heat in car, temperature guage was blowing sky high and shutting down engine. It was discovered that there was engine problems, so that was sorted along with new cylinder head gasket, everything worked fine until now. I again am getting no heat in car, finding it considerably harder to demist car (blower still working). Temperature gauge is rising to 3/4 level, but never goes above and does drop while driving, but continually goes up and down. Is this a thermostat problem or is it something else?

    I have a 2000 Daewoo Leganza. There is no heat at all only blowing cold air. Also notice smoke that comes from the engine from time to time when driving. As I'm in a small town in Kansas most places here only work on American cars. Does anyone know of a Daewoo service center in the Topeka, Kansas area? As far as the heater, could it be a hermostat problem or is it something else?

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

No heat


first make sure the radiator is topped off or full also the overflow is at proper level .. feel the hoses going into the cars firewall to see if they are warm or hot. if cold then the car is not letting hot water into the heater core inside the car . there is a control outside the firewall that might be at fault .

You have air in the cooling system, it needs bleeding, this is best done from the heater hoses. you cannot have a heating or cooling sysem that is not pressurised. no water no heater no demister no temp guage

No heat


27th Nov 2007, 15:49 To the above comment: You can't have a 2003 Leganza, because Daewoo stopped selling cars in N. America after the 2002 model year.
A non-operating heater could result from a thermostat that is stuck open, keeping the engine from getting up to normal operating temperature; but if that was happening then you would probably have a check engine light on too.
More likely you have either a stuck or broken temperature control for the heater. Temperature controls are either cable-, or vacuum-operated. Find yours in the heater hose somewhere and see whether you can move the linkage on it. If that causes the heater to work, then you have found your problem. If not, then you may have a clogged heater core, which would probably mean replacement (much more expensive than a thermostat replacement, unfortunately).
Btw, your mechanic does not sound too interested in figuring out what the problem is.
