    Hi Folks!
    My 94 Crown Vic PI w/250K (it's in excellent shape) has developed a coolant leak but I can't locate where it's coming from and am hoping the experts here can point me in the right direction so I can avoid 'explaratory surgery'.
    It's developed into a rather sizable leak in that a 100 mile trip I'll lost about 20oz. of fluid.
    It's coming from either right behind the water pump and/or right below the throttle body intake manifold at the front of the engine. I can only see some kind of a hose down there but can't see where the coolant is coming from or determine if that hose has anything to do with the coolant.
    I'd hate to have to pull off the intake manifold for nothing.
    Can someone tell me what's in that area that could have developed a coolant leak?
    Thanks so much for all your help!
    God bless,
    Peter

    Remove alternator and put the pressure on the rad system.
    They make coolant dye for the hard to find leaks.

    16 LBS if the cap is on the overflow tank
    13Lbs if the cap is on the radiator
    Those are what the caps are rated for, so don't go beyond that.

    I had a pin hole leak on a bypass hose - it was so fine you could not see it, it was spraying towards the radiator so i saw coolant dripping down the front of the radiator. Like a dumba$$ I replaced the radiator. When I put the new one in and got the same exact leak I finally dropped a shop cloth and watched the fluid hit the cloth and traced the leak.

    Any point is use the dye, cheap and easy enough to do.

    The dye would have been a lot cheaper than a new rad. :)
