    On my 94 I have small amounts of radiator residue on all my hose connections, the overflow box lid and then a large amount that is slowly heading down between the manifold and the valve cover from the front towards the back on the drivers side. Then I have some leaking down the front from the same corner. I haven't seen the truck go over 210 since I bought it, which was at christmas. I am also not getting much lower on Radiator fluid either. Maybe 1/2 an inch in the overflow. I've got just under 70K miles. Does anybody have any suggestions? I will try to get some pictures tonight. I don't want to drive it till it overheats or anything but I don't want to just replace every hose and find the problem is a bad manifold or even worse a head gasket. Its a 1995 k1500.
    Thanks for your help.

    most likely it's your hose. sometimes all you have to do is tighten it up a bit. carefull not to kink the hose.

    head gaskets usually come with a compression leak from the piston cylinder/head chamber, know as a blown head gasket. Also, check your engine oil. if it's a whitish color, you got water in there. IMO, I don't think your engine would of survived that long. blown head gaskets get worse as time goes by.

    as for the manifold, never really seen one fail on me.

    Does the truck have a 4.3L? IIRC they have had problems with the plastic fitting at the back of the block for heater return. Sometimes if you wiggle that hose they snap off from being brittle.

    Its a 5.7 non vortec. Its not from just the hose though its like from every place that there is a break in the system. I will get some pics tonight that should be able to explain it better. Its not a bad leak more like a seep.

    looks to me like your intake manifold gasket is shot...never seen it seep red like that before, course i still use the old green stuff that cats like to drink....
    pretty interesting, almost looks like its bleeding...
    but theres no question in my mind that at least that gasket needs replacing, why its all red at the over flow i have no idea

    I think that what happend was when the dealership recieved the truck it had the green stuff not the dexcool(red) that it should have. The guys on Pickuptruck.com think that it mixed with the green stuff when they flushed it and this is the result so I have to flush it extremely well and then replace the manifold gasket. Yehaa that will be fun. Thanks for all the replies.
