the car is a 94 civic hatch,all stock, and auto...

i flushed the coolant last weekend,cause it was filthy,old etc...
replaced with fresh coolant, bled it etc, now the cars temperature flucuates between almost overheating and normal temp while driving...it will go up slowly, then come back down ,then up and down, sometimes slow, sometimes faster...

also the car seems to stumble a lil now at idle and once in a while ,while driving, im thinking there still air in the system,or the thermostat is on its way out, can anyone help me put here, the car was fine before i flushed the coolant...
thanks..

ideas?

 

how well did you bleed it ? i think thats the first and easiest thing to try and do

 

i had a problem a little like this,my temp kept getting hotter and hotter and then it would drop and then do it again,and i kept having to keep adding coolant. it turned out to be that i had a blown head gasket

 

^ Ouch. I dont think this guy has that problem.

Try bleeding your system again and that should fix it.

 

thanks man, any tips on bleeding it, maybe im not doing it right...thanks..

btw im not leaking any coolant

yeah i agree try to bleed it again.... it might work..

 

Hmmm, it does sound like a blown head gasket, thats what mine used to do. Could it be a thermostat problem?

 

ok i bled it again yesterda and it had a ton of air in the ststem, hopefully all is well now..

i dont see how i could have blown a headgasket, by flushing the coolant..
