New thermostat

Hello,

I have a 1993 acura integra with a 1.6l dohc engine. I just replaced the thermostat and when I took it for a drive I noticed the heater only worked when I was accelerating, the temp gauge read in a normal range. I checked the upper rad hose and noticed it was very hot but the lower hose was still cool.

is it possible I have an air lock situation? What can I do to fix this? Thanks for the help.

Being a Honda it might have a manual heater control valve that is only opening a little bit, but more pressure is more flow

Hi, I have an 86 honda civic and when I got my radiater fixed the guyes told me I wound have to bleed the air out of the system. To do this there should be a bleeder valve on or near the top hose. With the car running you slowly open the valve and whatch the water coming out when you have a continulous streem of water you tighten up again. Hope this helps, :)
