Thread: RPMs and temp gauge stutter???¿

I cant get all the air our of mine either i think, where all should i bleed from?

Sometimes when I floor it it drops the gauge

Radiator there's a drain plug at the bottom

where in mass are u from, put the car on a ramp at an angle and open the radiator cap and let the car run, if theres air bubbles then its going to float upwards towards cap as the heatcore is a little higher than the top of the rad. if that doesnt work them replace ur coolant temp sensors, maybe 20 a piece
