today my car was overheating and found out that a hose underneath the intake manifold..a hose was not clamped on tight enough and antifreeze was leaking so i went to auto zone to get a new peaice of hose with clamps and antifreeze and when i installed it and put in new anti freeze.. now my temperature gauge stays at cold unless im at a stop then goes up a little and when im driving it goes back down to cold?? any suggestions and is it something to be worried about??

 

Bleed the air out of the system

 

replace the thermostat i had this problem when u rev the motor it pushes coolant past the lil O-ring that stops the coolant from entering the block until its open. Replace the thermostat and im sure this problem will go away.
