OK,

my car is leaking coolant everywhere. it leaks right below the radiator cap, and behind the passenger side header. anybody got an idea of whats going on?

thanks

 

Well......to me it sounds like coolant is leaking from the places u described. There isnt really much we can do accept just tell u to look for exactly where its coming from. There is prolly a crack in the hose or something.

 

I just fixed a coolant leak similar to yours, it was leaking from the radiator cap. The previous owner installed a K-mart radiator cap and it obviously wasn't doing the trick so I installed a brand new GM cap and problem solved. Also, for the passenger side leak, there are heater hoses that run around that area so it could possibly be that. Give it a good inspection and hopefully you will find your leak/leaks.

 

Could be a cracked head or blown head gasket leaking at the back of the motor, but I would check hoses first.
