1997 acura integra overheating when I get on it runs good when driving and shifting at 2Gs but if I shift at 3gs it jumps all the way to hot have changed the thermostat and bottom hose still cold while top is hot??? If I let sit goes back to good fans are running as soon as I start the car but I think po must have wired to come on. And does that ground wire have to be on the valve cover have replaced it but don't know what that does.just seen where other guy was having same proplem and replaced that wire and that fixed his proplem

If the the lower hose is cold and it runs hot then that tells me its not circulating.also there had to be a problem before if the fans are wired to come on when car is first started,may have a bad waterpump or exhaust is getting into cooling system, have a block test done to see if there a bad head gasket first before you continue, good luck hope this helps.
no the thermostant will still open,the coolant is held in the motor until thermostant opens the fan is only cooling whats in the radiator,you did put thermostant in facing the right way,(the spring goes toward the inside of housing,have a block test done this will help alot, hope this is helpful.
