all the questions asked by F22-Guru, are all excelent questions.......lets go back to basics,,
# 1 have enough coolant in readiator
# 2 bleed system properly
# 3 pressure test system for leaks,, if any repair them
# 4 pressure test radiator cap, look at rubber gasket for any cracks or tears.if any replace cap,,
A quick test. start car put a/c on,, both fans should come on, if they do, it tells us fuses, relays. motors are ok.
# 5 start car up and let it warm up. when warm enough
# 6 feel the bottom radiator hose , should feel almost but not quite as hot as top radiator hose/
# 7 if it does , thermostat is opening ok,, if it feels cool , install a new HONDA factory t-stat and gasket and retry the whole thing..
# 7 if with a new t-stat , car warm, and lower hose still feels cool , you got corroded blades in the water pump..
# 8 if lower hose feels hot, let car run and wait for fans to come on..
# 9 if they come on you are all set.., if they do not come on, and came on with the a/c .. bypass the switch at t-stat housing..unplug it and jump the 2 wires together ,if fans come on replace the switch ,,
Now if fans did not come on with a/c on , car could be low on freon ,also chk the fuses, relays ..if ok let me know i will walk you how to troubleshoot them
try all of this , do not jump around and post results..,,,,,,
