    Heater Core Replacement

    I will be replacing my heater core shortly, but I have a question:
    Is there any reason I shouldn't put some short lengths of heater hose off of the heater core, just enough to go through the firewall a little bit, and then connect with unions on the forward side of the firewall to the remainder of the heater hose runs. It would make installing the heater easier, and would allow it to be an easier repair if heater hoses ever need to be replaced.
    It seems like an obvious thing to do, but I've never heard of anyone doing it.

    You can use long pieces of 5/8 hose to reach there final destination. Hook them to the heater first and then thread the heater box with hosed through from the inside. Cut the hoses to fit where they need to go. Just unhook them to work on the heater box. You'll probably have one go to the intake plenum heater and the other to the engine block.

    The reason they put the hose hanger strap on the shock tower brace was to tether all the excess hose you were suppose to have to need to unbolt and pull the heater box away from the firewall enough to get to those clamps. Of course, you always ran the risk of spillage of antifreeze inside the cabin. Twas a funky affair.

    You could use short nubbins of hose and some straight pipe just long enough to protrude past the firewall. Keep in mind that the more junctions the greater source of leaks. Get new hose and new clamps and a tube that won't corrode. Copper plumbing like John said would probably be just fine.

    V8 cars were worse since the holes in the firewall were 'right where' the valve cover was. And worse yet with the new aluminium valve covers.

    I ran a single piece of hose just because I think it looks nicer and as Roger said, less chance of a leak (although a small chance).

    And it wasn't really that much more difficult to install or take off. I keep an assortment of plugs around to jam in the hose when I need to drop the heater box. And that's not too often.

    So either way is good IMHO. Whatever floats your boat!

    I also used one-piece hoses because I like the look better. I'm probably removing the heater box soon and feel i can "blow out" 99% of the coolant before tilting the box out. I can also plug the hoses before removal. Not worth the "ug" look (my opinion) and the cost of additional 4 hose clamps to attempt to keep the spill down. The shorter hoses would still need to go out through the cab anyway, so....... I guess this is keeping my boat afloat.
