Bleed the coolant. Take the coolant cap off. Turn the car on, put the heater on full and wait untill the fan goes on. Once that happens all the air bubbles should be out of the system. Also ensure your car is on level ground

nah thats not the problem


all cars do it its just a fast heating its just to make the car get to operating temp faster so it doesnt take all day for it to get to op temp.



mine does it and my old supra does it and my 77 celica does it its a standard thing

when i start up it revs to 3000 then after 5-10mins once its warm it it drops and idles up and down between roughly 1000-2000rpm. i tried the heater thing but nothing happens just warms up quicker. also sumtimes doesnt stop revving up and down when im driving around.

theres actually a bleeder bolt that you unscrew to let the air out

its not on the radiator.. its on the other end of either the top radiator hose or the bottom radiator hose.. cant remember off the top of my head..

Top, near where the radiator hose goes into the block. it looks like a nipple on top of a threaded bolt.

hi fudge
i dunno if this is simliar to ur problem but i had
extremely high idle ---> that was solved by bleeding coolant
then i had a jumpy idle ---> fixed by changing thermastat

good luck.
