my 95 civic starts to over heat after bout half hour of driving but it does not over heat that bad just a little over half mark and it cools down when ur just idling

 

check if ur rad is holding pressure if not, its either a small leak you obviously cannot find or the rad cap. If not either of these then it could possibly be ur thermostat. its worn out and not opening/shutting properly. AND if its not these three things I can think of, It prob. is ur WATERPUMP! thats if u either have significant milage and never replaced it. Oh and if your cars condition get worse to where it gets past the H symbol. Dont drive on it until you get it looked at. You could risk overheated the cylinder head which can lead to warping then you would be in some deep $hiTT!!! JUSt Check everything in the cooling Department.

 

'lil over the half mark' is where it should be..durr.

 

mine is little bit under the half mark.

 

Well, as long as it's lingering around half..your good to gooo.
