You should replace that small length of heater hose while it's out, accessible.  It's 45+ years old.

Jeff,

Did you see any of the threads on the forum about dash repair? A number of people have had good results with filling the dash and using SEM products to recolor and texture the repairs

I just went and had a look at that. They actually look very good. I will se how my end result is when it is done and make my final decision then.

That is a good idea, I will do that while I can still get to it.

Actually, to go a little further, you might pressure test the system while it's out.  The control valves tend to go bad also, besides the common leaky heater core.

Some of the guys have developed alternative cores as replacements, and alternative control valves.  Worthy upgrades.  CO did both.  @Captain Obvious

Good idea....the last thing Jeff wants to do is to pull it out one the dash is installed.

This week I redo my Datsun's dash repair with a factory style textured finish.

Much better!!!

The heater valves are hard to service and can be a little pricey. Some other guys have found newer parts that will work as a suitable replacement with some rework.

Thanks for taking that "bad toupee " off the dash.  The repair is much, much better.

I have got one coming from Japan for about AU$100. Nissan in Aus wanted around $350!

Can you post the seller info, or is it a one time eBay thing?  Looks like about $72 US.  Even with shipping it's probably a good deal for a straight replacement part.  Is it NOS, or used?

Mine was a new genuine Nissan one from a one off seller (it was US$69). I did a quick search and there is one in the US on ebay at the moment for not much more. Just do a search ?

I have spent the last week sweating it out in the heat fitting seatbelts and reassembling the doors.
