Need to find a new radiator for my 64 jetstar 88. I could have mine rebuilt but looking for other options since it is costly. Any ideas? Would one from an 88 work with my 350?

 

re-cored mine - $500

 

The part number for a Jetstar 88 radiator is different than a Dynamic 88.
So I would presume them to be different .
The part number is either 3001441 without A/C or 3001449 with A/C for your Jetstar radiator.

 

The service number 3001441 had original part number 3158840 with std. trans. & no A/C and 3158841 with Hydramatic & no A/C. The 3001449 service number was originally 3158849 with A/C or special cooling. All this may prove to be near useless; Hollander shows no crossovers to any other vehicles. If you don't mind making/drilling brackets and/or using hose converters you may find something close that works. I'm assuming that yours is beyond repair.

They will make a completely new radiator to your order including high efficiency cores, I have one on my 63.

 

This radiator is for a 394 . The OP has a Jetstar 88 with a 330 , different radiator .

 

I wonder what the difference between the 2 models are. It's still the same car just different engine.

 

The Jetstar 88 was the 3300 series; the Dynamic 88 was the 3400 series. Cooling system capacities were:
3300 with A/C: 18-1/2 quarts
3300 with heater only: 17 quarts
3400 with A/C: 21-1/2 quarts
3400 with heater only: 19-3/4 quarts
These differences could be in the radiator or the engine, or both.
Volume 1, page 3-32 of the 1964 Oldsmobile service manual shows the radiator inlet hose for the 3300 series being on the passenger side. It shows the radiator inlet hose for the 3400 series being on the driver's side. The outlet hose for both series' radiator is in the same place (driver's side). Perhaps you could make it work by using a different upper hose, if room otherwise allows. Check the placement of your accessories on the engine. Most conflicts occur with the alternator and/or the A/C compressor.

 

Look a little further on the site, they should have what you need.

two motors-394BB or first year 330 SB, would Olds actually use two different core supports? If the core supports are the same you have more options especially with flex hoses, unless your staying original.....

 

As long as I can bolt it in I'm fine. I'd actually like a bigger radiator since we live in Florida and will be using ac alot. It now has a 350, was the 330.
