So i have a 2000 honda civic ex. The radiator started leaking from the top seal so i purchased a new one and installed it. Well the same thing is occurring with the new one. It really starts to leak bad when i press the gas. I have also noticed the radiator fan doesn't turn on. I replaced the fan relay as well the car isn't overheating just leaking from that seal. Is there something else i should be trying here. Any and all responses are helpful. I don't have my manual either.

 

u replace the cap too?
