95 civic lx hardly heats up

you say that you have little heat. what does the temp guage say? while the car is running check and
feel the hoses to the radiator. are they hot? if so i
would check to see if the hoses going to he heater core are hot. the problem might be that the heater core is slightly clogged if this is the problem i would back flush the heater core.

The temp guage(no numbers just H and C) goes to just slightly below 1/2 way up. I am by no means a mechanic:) But I am confused.Both heater core hoses are warm.Top hose from radiator is warm but bottom hose that goes to the thermostat seems cold and empty?

I am currrently letting the car idle in my driveway to see if there is any air I can get out of the system.

Would you recommend a purge by a proffesional place or?

I have had to add some antifreeze in the 15 minutes it has been running but there are no leaks.

I appreciate all the info you folks can provide.Oh I also bought a new radiator cap I figured it couldn't hurt:)

Bill if you are in Wisconsin I know you really want the heat. Here is my two and half cents worth. From experience, this is not the water pump. Usually when they get weak they leak. You will probably find that the cap did not fix it.

Monitor the fluid level very close. If there are no leaks and the fluid level drops and keeps doing that you are looking at a head gasket problem.

The other suggestion about a flush is a good one as well.

Please also consider that the car's damper for the heat control may not be opening all the way to let out the hot air and is mixing with some outside cold air.

the bottom hose seems empty? try squeezing it a couple of times and listen if you hear anything or feel anti freeze in hose. iot might have a vapor lock. did you have to put more antifreeze in it that you mentioned?
