so i replaced a head gasket on a 1993 civic 1.6l drove around all day then next day it over heats again pressure rising coolant tank over flow but im noticing my cooling fan not coming on ive replaced both coolant temp sensors and the fuse and relay whats the deal why am i over heating again?

 

check your wiring for your fan jump the plug on your thermostat housing with a paperclip with the car key turned on not started. the fan should come on if not u need to check your wiring.

 

try this mos def

 

+1 on this.. if you look on those areas this may be the problem..

 

I feel you on this one. I replaced everything on my girls 98 accord and that thing still over heats. Fan, switches, relays, head gasket, water pump, radiator, hoses. So I just threw a switch on it and told her to turn it on whenever she drives. Not the best thing because its not proper but their was nothing left to replace besides doing a complete overhaul main bearings and ring etc. You can take wire and jump your fan straight to the battery to make sure it works.
