    Help - No Pressure

    I need a little help guys.


    A few weekends ago I developed a leak in the upper radiator hose. It split and antifreeze went everywhere.


    The hose was replaced, but now it has very little pressure if any when the truck it at operating temperature. No leaks that I can see.


    I replaced the overflow tank cap and there is no difference.


    Any ideas what is going on?

    Probably an air pocket. Open the overflow cap and leave it off while letting the engine warm up. Get the engine nice and hot and squeeze the upper radiator hose multiple times to remove any air pockets. It may take time to work out the air from the system.
