i tried air bleed the system again, still overheats.
i'm going to replace water pump tmr. hope replacing water pump will fix this problem.

 

Yea when they replace your waterpump timing belt should be done while everything is apart. And the new water pumps have changes done to them to ensure this problem wont occur again. It had something to do with the seals that dosent allow water flow through the system. Thats what my tech told me.

 

yup ill do what you said. i got the new waterpump today n new t belt is on its way. i didn't have time to take everything apart today. i might start tmr or day after tmr.
ill let you know the results in couple days. thanks alot for your info.
this forum is really helpful, i've already went thru diy section n it doesn't look hard job.

 

the problem was the water pump. sprocket and the fin was turning independently.
just changed timing belt and water pump. took me bout 3 hours but wasn't that hard.
glad no sign of overheating now, but still no heat from vents.
one of the heater core hose get hot but the other hose is warm.
i flushed heater core couple days ago, didn't seem like plugged.
i got tired im going to look at it tmr.

 

thx everyone for great help
everything works fine now.

 

Glad it worked out.. what was the last problem with the heat?

 

good deal!

 

i'm not sure what was the last problem. i always had temp setting at hot, i lowered it to 28-29 and it started blow hot air.
so far no problems.
thx again guys and happy new year

 

Thanks for everyones help on this. My heater is now working. The dealer needed to flush this out a few times and bleed the system. I told them what you guys said and they said "Oh Yeah sometimes we need to do that". Um after two years of no heat would have been nice if they realized that sooner :-) they also replaced the radiator which they claimed they needed to do to get the heater working and they wouldn't do the flush without replacing that. When they flushed the system they found a "glue" like substance inside they said, noone wasn't sure where that came from since they service the car, maybe it is something breaking down. Thanks again.

 

glad you fixed heating problem too. good luck with your car
i've just noticed smoke coming out from radiator. coolant level was okay tho.
time to change radiator i guess this is never ending story.
