2005 honda civic overgeating at idle and loosing coolant.
So ive been having a overheating at idle problem
with my 2005 honda civic ex. Only 76000 miles. Ive
replaced the thermostat twice thinking that was
the issue. Still overheats. Ive done a pressure test
as well. The pressure dropped from 16 psi to 15
psi within about 30 minutes. No visible leaks. Ive
searched everywhere. No coolant in the oil or
residue on the oil cap. Water pump is working. Any
advice on what it could be?
