    I recently acquired this car cheaply and replaced the headgasket and cleaned the egr system.
    Water pump is working heat currently is not and I'm getting an overheating issue pulling the mountain with antifreeze coming out of the relief on the coolant reservoir.
    Fans- working
    Water pump- working
    Heat- not working
    Egr- spotless
    Egr valve- clean and functioning
    techstream shows everything working as should be no faults other than B1503
    Sometimes the reservoir has pressure other times it doesn't
    No leaks with the headgasket or miss fires
    Engine coolant isn't low
    Previous owner used Red devil block sealant ‍and I'm leaning towards radiator
    Opinions are welcome
