first off i live in ny and its cold now.


i have a 2005 g35 coupe with auto tranny 37k miles.


I have no heat at idle. heat work fine when driving

i bled the air then i took it to the dealership for a coolant flush n fill, and right now i still have the same problem..


Today i changed the thermostat and there is still no heat when the car is at idle.

right now from what i know the heater core is not leaking and there is no leak at all.



The Heater core inlet hose is warm but the heater core outlet hose does not get warm.

Can this be the water pump at 37k miles? need advise pleaseeee

 

If the water pump was bad you'd have far worse issues than a cold car at idle. You do realize it takes a while for the heater to work, the temp would have to be up close to normal operating temperature. Don't forget to use your seat warmers, my wife loves those.

bad core.

 

could be a clogged heater core....rarely happens

 

i ran running water through the heater core with out a problem.

i ran the water very slowly too.

 

its not that cold don't be a pansy.

 

/\ .. lol ..




my heater kicks in after a few minutes . i put the heat up half way .. and on 80 ..

and the nut warmers work great lol ..

especially this morning digging myself out of all the snow from last night ...

 

store the car in the winter like I

 

Did this get resolved. My 03 is doing the same. No heat at idle, but as soon as you raise the idle heat comes out.

 

check coolant level, thats the first/ easy step

 

More importantly, check and bleed for air in the coolant system.
