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.

Anyone have a decent radiator and shrouds and hardware for a 1964 Cadillac deville. I have an alum. radiator and I'm deciding on to fix it or back to the original one. If I fix it I won't need parts.


64 Recirc/Fresh Air Door Actuator replaced; FROM THE INSIDE.

Posted by Norman Silverman on February 4, 2019 at 11:21pm 8 Comments

I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back.  It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh…
