Question about 2005 Hyundai Elantra

1 Answer

No heat in the car

I have changed the thermostat and the car still has no heat until the car's temp is already at its normal temp, and only when the RPMs are at about 3000 will the car begin to warm up. My biggest question is, could the ignition coolant sensor affect the heat or is it more likly now the heater core?

Check louvers that allow air through the heater core ducts. You should hear them move when you change from cold setting to hot setting on temperature dial. Listen closley to the ductwork.

How are you determining that it's over heating ? Temp. Gauge ? Do the cooling fans turn on ? 5 different mechanics ? Did any of them hook up a scan tool , to see what the coolant temp is . Use a inferred temp tool to see what it shows for temp.

check the coolant level first! and change the thermostat if need be. sit in car until the temp. guage reads normal temp. if it is normal, and still no good heat. it is possibly the thermostat thats sticking. when changing coolant remember to bleed air from system while putting fluid in. it may also need a good flush. good-luck !! i live here in ny and today the wind chill is 8 below zero.

Porbably is normal temp. Temps are higher, these days, to assist in low emissions. Needs to be 200 to 230 range, usually. The thermostat does not open until just under 200 or so.

Had a simular problem with a 318 myself, they are notorious to get air locked after replacing the thermostat, should have a blead screw on the main water hose, start the car and get up to temp then slowly undo the screw until water starts seeping, should be bubbly, persist with topping up the water until water runs clear, do not drive the car untill air lock is clear or it could blow the head gasket£££££
and or radiator.

No heat in my 2002 chevy s-10. Already changed


The heat is controled by a control valve installed in one of the heater hoses. It normally is controled by eather a vaccuum line or a cable coming from inside the truck at the dash where you slide the hot to cold adjustment.Find the valve under the hood at the hose,have someone move the control inside the truck.If its vaccuum you can pull off the hose and see if you have vac.If its a cable you should se it move.

have you try to change oil? some times engine heat does' not just come from malfunctioning of the cooling system . But sometimes its the oil that runs to the engine . if the engine oil is dirty already it could also cause the engine to over heat. do to change the engine oil of your Acura Legend.
