Correct Series 1 Radiator

[Phred]

Here is an original 71' that has been recored with a four row core. It's for sale for $180.00 but would be more of a pick up item, as shipping would probably be $$$ since they are kind of heavy.

Good question. Unfortunately I don't have a good answer for you. I assume that a good eye would be able to look at the top & or bottom tanks and tell if it was original or not, but someone else will have to comment on that. Going under that assumption, I took my original radiator to a local shop and had it re-cored with a three-row, tight-finned replacement (as recommended by the shop). The radiator man explained to me that there have been many advances in cooling technology since the early '70s, and that a good quality core of current technology should solve any cooling problems encountered with a '70s vintage original. What I like about that approach is that the top & bottom tanks are the original parts, and the 'new' one looks just like the original part. I have several original rads sitting around if you need one to get re-cored. (They might work as is, but I couldn't guarantee that....)

Thanks John,

I am in no rush. Just PM me when you get some pictures. My engine will be out until I get the body work and paint done.

Let me know. Thanks, John

Boy, that looks very similar to what I have in my car right now. The thing that throws me off is I found a plate welded to the top tank that says "Ray's Radiator Repair".

Maybe the PO just had it recored. I will look at pictures and compare. Thanks for the post!

Just a couple years back I bought a new one from Nissan. It was set up for an automatic transmission line. They told me that it was all they stocked now. That way they only have one on the shelf...

Thanks for the info. Will come in handy to some but I am looking for an exact replacement for mine and I have a 4 speed.

It looks like mine is correct. Thanks for the pictures. As you can see from the pictures, it has a tag that was soldered on by "Karls Radiator" I found the invoice for the recore in my files. I guess "Karl" was pretty proud of his work and probably offered a warranty on the radiator which he kept track of with the serial number on the tag.

Thanks again!

The radiator on my '71 was recored as a three row after my water pump shaft broke in the late 1970s and the fan augered through the two row. The two row worked fairly well with the AC, but the three row kept me from having to turn on the heater in traffic to increase circulation.

I installed a new AC system this summer and added an electric fan. No problems with the 100+ degree weather in Palm Springs.

How can you visibly tell if you have a 2 or 3 row? Do you look inside and count rows or is it visible from the outside?

Look inside the filler cap and count the rows.

When I look inside I see one flat piece of metal running the length of the radiator. This metal has 2 rows of "vents" in it. I am assuming this means I have a 2 row.
