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 .

No interior heat in my 2000 daewoo nubira


3 possible issues here,

the first is that your thermostat is stuck open, when this happens the air will barely be warm, luke warm at best, replacing the thermostat will fix this problem

the second, is that you have low coolant levels, when your coolant levels are way low, your heater core doesn't get the proper amount of coolant (if any) and the system blows cold air instead of heated air.

The third and final possibility, is that your heater core has clogged up (usually happens when stop leak or some type of radiator sealant is used) when this happens you can feel warm air when accelerating (test this by gently reving the vehicle and holding the rpm's when it is in park and holding your hands over the defrost vent to check for heat.

If you can tell me what symptom your vehicle is having I can help with instruction on how to fix it thanks cnc_couple@live.com

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...


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.

2000 Daewoo Leganza heat gets just luke warm!!!


I have the same problem. we changed the thermastat. the engine coolant was full of muck and looked rusty like something was rusting away.we then back flushed the system including the heater core.It's alot better but we think the water pump propellers are rusting away. this sometimes happens. so we are keeping an eye on the temp to see if it is getting to hot or over heating if so the the water pump needs replacing. I would have the system back flushed to see if that helps you could be having the same problem I' having. Hope this helps.
