Source for Replacement Radiator for my 64 with AC

I want to replace the radiator in my 64 DeVille. 

Which vendor is a good source for an OEM type unit?

Thanks. Beautiful, fresh green antifreeze and a properly timed/tuned car. No, this is simply a case of radiator fatigue, which I confirmed with my laser temperature gauge; cool spots in a couple of places suggest blockages. Not enough to overheat the car (because it runs well and is in proper tune) but enough to cause it to run just a bit hotter than I would like. Still the original radiator, which I am first going to have boiled out, rodded out and sealed up. Then we'll see.

How old is your antifreeze ?
Old antireeze will not disapate heat very well
Most have a one year or 5 year life depending on the brand

Retarded timing will cause the engine to run hotter
Only readjust the timing after installing new points unless you have a pertronics ignition system
Then you can reajust without causing a problem

Enjoy or your doing it wrong

Maybe just a good flush of the radiator and the engine block might do it. But a newly painted "original" radiator is nice as well.

I think that's what I'll do just as soon as I get the car back from the body shop where it is being carefully polished out. My car does not overheat, nor does it overflow when shut off but the needle goes to just below half in traffic. All my other (properly running) Cadillacs ran at one needle width below the first quarter (admittedly, those were much newer cars but that's what i recall).

Take your radiator to a good local shop and have it rebuilt with a new core. You can ask for a thicker core so cooling is increased.

On my -66 DeVille Cab I had a bus repair shop! take it apart and solder in a new core. It was about 1 cm thicker and helped with cooling.

New paint on old frame with new core and you have as close as original as you can ever get.

Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…

I just wanted to say a thank you to Kurt for steering me to the tech tips page on V.I.N. locations.  Excellent information.  Thanks a bundle.

V.I.N. where?

Posted by Robert Pellow on April 18, 2021 at 1:41pm 6 Comments

Where can I find the V.I.N. on a 63 convertible?  The usual space at the base of the interior windshield on the driver's side has been decimated by weather.

63 Trunk detail

Posted by Bob Pontius on April 8, 2021 at 3:07pm 6 Comments

Jason, I liked the detail and information you have provided. I would like to do mine similar to yours. Can you help? Do you have trunk material? OPGI is sending the trunk product for my 63 Fleetwood. But it does cover the entire trunk as yours was done. If you do not have can you give me a reference? Thanks!! Bob
