darn f*cking radiators from http://www.radiator.com are pieces of sh*t. the thing overheats with just 30mins of hard driving. had to pull my car over to cool down. check very thorough for leaks. their are none. i made sure of it. OEM fit ment my ***! had to get hoseclamps from the hardware store. dunno what else could be wrong except the cheap *** radiator. advertised at $123 but they actually charged my $154. brand new, and i already see rust inside. the warranty is bullshit! cant even refund it. only thing their willing to do is raplace it with another one of their peices of crap! sorry. but im pissed off! waste of my $154 dollars! and my time!
im gonna go back with OEM from http://www.hondaautomotiveparts.com $179 for a new radiator. seriously thinking about fluidyne. dont ever want to deal with overheating. its a bitch!

weird ive had two of em for 2 diff cars and had great luck w/ em. im using a del-sol sized rad on my civic hybrid too no problems.

did you bleed it properly and make sure its not the cap,thermostat,fan or switch? relay? fan coming on?
