‘65 Imperial Heater Core

[ab777]

On my recently acquired ‘65 Imperial, the heater core is bypassed, but I was wondering what the implications are for this car?

I live in Texas, so it’s not really cold down here for the most part, but I am trying to see if this could negatively affect the car’s cooling?

For those that have done it, how hard of a task was it? Just trying to figure out what route to take with this.

The heater core on one of my 1977 cars started to leak, after being replaced once before. I got the block-off rubber caps at the HELP! rack to block the pipes at the water pump. NO affect on the temp gauge readings.

For general principles, you can start searching for a heater core. IF it gets that cold in H-town again, you won't be driving that car anyway, I suspect.

For sure on the driving it during the cold weather part. When it gets awfully cold here once in a while driving a car like this is the least thing that I would like to do.

But generally speaking does the glovebox need to come out only or the whole dashboard?

Best thing to do is download a Factory Service Manual (FSM) from MyMopar Get a parts manual while you're there too.

To answer your question, I am fairly sure it comes out through the engine compartment side of the firewall. Once you download the FSM, there's a procedure for removing it (section 1) if you don't have A/C and a procedure (section 24) if you have A/C.

Many years ago, a friend was having over heating problem on a '72(?) Valiant with a /6. Problem started when a leaking heater had been by-passed. I found the heater hoses joined with a short tube. On a whim, I replaced the tube with a wooden dowel. Over heating solved! My "take away" was that without the heater core, more coolant was by-passing the radiator and reduced the cooling. Just my experience. Lindsay

I just bypassed the one in my 64. Leaking all over the floor. I can't remember the last time I used the heater in any of my old cars. No effect on cooling. The system ads a little extra capacity but the flow is shut off unless it is in use so there is no advantage there.
