i hope someone can help me...

my car is slightly overheating..the needle is reading over the half point.. i have a d16z6 in my crx and i just changed the coolant/water recently. Is it my thermostat? the car doesnt overheat all the way..i was wondering if it could be my radiator cap? My fan turns on, but its the a/c fan not the regular one....i havent had ac in my car since the swap. maybe someone can help..thanks

 

You're saying this is happening since you changed the coolant, and was OK before? It's possible some crud broke loose and is clogging your T-stat. Might as well replace it if you're going to open it up. I recommend a Honda OEM stat if you do. Also, make sure there is no air in the system.
