Question about 2000 Daewoo Leganza
The heater has "ran cold for a little part of one day recently, but when I put my hands over the radiator i can feel the driver side of it is way hotter than the left. So I'm stumped.
It sounds like the radiator. A reverse flush might clear up the blockage.

Got similar problems: Pump bearings were very noisy so pump was replaced. (Which would have led to timing belt failure; VERY expensive.)
Thermostat replaced. Rad Cap (well, header tank cap) replaced.
I notice there are two fan relays but that the fans never go into Hi-Speed mode, even though the temp eventually gets to boiling point & the cap opens to relieve the pressure.
The sensor near the 'Stat I am sure is for the dashboard temp gauge. So, which sensor sends the appropiate signal to the Fan relays?
Next step is a reverse flush of the rad & heater matrix.

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.

there's a sensor on the radiator that tells the fan to come on a serten temp,replace that,there normally on the side,just release the clip and pull it out,make sure it cold before you remove it as the water will come out.

More than likely there is an air pocket in the cooling/heating system. If there is no vent hole valve that is in the high point of the cooling system then what you would want to do is remove the radiator cap (when cool) to avoid getting burned, park the vehicle slightly uphill and start the vehicle and let it run til the engine gets hot enough to open the thermostat and burp out the trapped air. Many of todays vehicles don't ever really get hot enough to burp out system or the pressure in the system is too high to allow the trapped air to escape, that is why you want to remove the radiator cap. Hope this helps. If it does please give me thumbs up. Good luck.
