just out in a new longblock and coolant seems to be leaking really slowly somewhere or disappearing somehow. sometimes ill see a small puddle of coolant under my car, but cant spot the leak place. and sometimes ill take it for a drive, and there coolant level would stay the same. i havent seen any smoking and there is no oil in my radiator, so im pretty positive theres no busted head gasket.

anyone ever have this prob or know how to fix it? thanks!!!

get that stuff from an automotive store its flourescent die and use a blacklight to find the leak... it works wonders.

thanks man! i wonder if coolant will reflect with balck light without the dye. i got a black liht that plugs into the cig thing!

check your hoses to see if they are tight, when i first did my swap after i would drive it and let it cool my upper and lower hose would leak little and i would notice some antifreeze level down ,so i tightened them up and havent leaked any yet

ive checked that, because i did that the first time i changed a new radiator, i put my fingers on the bottom hose and didnt feel a thing. imma hit up the store tomorrow and get that black light active dye. thanks guys! hope i can fix this soon, so much coolant isnt cheap sheesh! lol

on the side note, i got 39 miles per gallon on my 1st fill up! thats going top speed of 65, mostly freeway, due to breaking in new clutch! omg 39 mpg , can u believe it
