    Don't know what that means, never ever heard of that. If you have water inside then the core needs no be replaced. You can still drive the car if you connect a hose from the water pump to the intake which bypasses the heater core.

    thanks mark
    what do you mean if you connect a hose {what hose ] from the water pump
    do you mean disconnect from water pump to intake of the pump which.
    or do you mean disconnect both pipes from core outlet and connect together

    I used a piece of copper tubing and hose clamps to splice the two hoses together. (Yes, they are different sizes.)

    Don't worry about reaching the hoses at the firewall end. You can cut them off in a convenient place for your splice because you should replace the hoses along with the heater core. (When you get around to it.)

    Good Luck!

    In the past I've just used the largest of the 2 heater hoses. But
    if you want it to look nice, just go to an Auto store and get a foot
    of heater hose (the larger of the 2).

    1/2" ID(IIRC) copper tubing and a couple of hose clamps.

    It will be tight in one hose and a little sloppy in the other but the clamps will seal it up.

    if I buy a foot of 3/4 hose ,that will not fit over the 5/8 hose to clamp with
    a hose clamp plus the hose will probably kink.
    i'm not real smart when it comes to auto work, but I have to take care of this

    go to a parts place and get a 1/2 to 3/4 adaptor take the hose off the water pump and the intake and hook together top off with coolant or water and go.
