Imperial Cooling System Part Numbers

Imperial Home Page -> Parts -> Cooling System -> Numbers

Read the 1953 - 1961 Chrysler parts manual which part numbers for the cooling system on these models.

WATER PUMP
Napa or Lester Numbering System - Noted with N or L

FAN CLUTCHES*
400-413-440 318-360

NOTE: Most fan clutches can be matched by comparing the distance from the mounting flange to the center where the fan mounts and the diameter of the fan ( usually about 18 inches ). Additionally there is the choice between thermostatic or centrifugal type. Thermostatic is more common, where the fan does not engage until the car has reached operating temperature.

 

RADIATORS* 

*There are few listings for Imperial radiators. It is possible to take your core dimensions, mounting flange dimensions, size and location of the inlet and outlet, and overall dimensions to a parts store and try and match one up. In may be necessary to have the unit re-cored. Usually the tanks can be saved and the new core is simply soldered into place. The advantage is that newer, more efficient cores are available and the cost is not that much more than new radiators, if they were available.

NOTES ABOUT THESE PART NUMBERS: Due to the fact that Chrysler no longer produces many of these parts and that Chrysler part numbers are quite often superseded or not in the Chrysler parts system any longer, aftermarket numbers are used. If enough current and correct Chrysler numbers are available, they can be added for what is still available from Chrysler.

I have arbitrarily chosen NAPA parts for the aftermarket, simply because of the availability of NAPA outlets and the fact that I have previously worked in their parts system. This IS NOT an expressed or implied advertisement or endorsement to use these products. MOST PARTS OUTLETS CAN INTERCHANGE THESE NUMBERS IF YOU DO NOT HAVE A LOCAL NAPA OR PREFER NOT TO PURCHASE FROM THEM.

IMPORTANT: ALL THESE REFERENCES HAVE BEEN ONLY SEARCHED FOR IMPERIAL OR NYB AS APPLICABLE. WHEN RESEARCHING THESE PART NUMBERS I SEARCHED FOR IMPERIAL, MODEL YEAR, ENGINE SIZE AND ANY OTHER NECESSARY DATA PERTINENT FOR THAT PARTICULAR PART.

FOR EACH GROUP OF PARTS THE SOURCE AND BRAND WILL BE LISTED< AS WELL AS ANY IMPORTANCE OF THE PART NUMBERS USED. IN THE CASE OF REBUILDABLE PARTS OR PARTS NOT EXPRESSLY NAPA- NOTES WILL INDICATE THE USE OF SUCH NUMBERS AND SOURCE.

Now when some uninterested, uncaring and uninformed counterman says " they didn't make that in that year......" or " its not listed...." you will have the upper-hand.

NOTES ON REBUILDABLE PARTS:  Many times a part is not available because the rebuilder has no "cores" from which to remanufacture a part from. It is usually possible and sometimes cheaper to send your part in - if you can be without the vehicle for the time required. Most of these parts are rebuilt by major suppliers to parts stores, regardless of the individual outlet. ( It is not uncommon for competing retail stores to be supplied by the same rebuilder) Some parts require the services of smaller specialized rebuilders, especially for vintage or very rare applications...

The following is a non inclusive list of many of the parts that can be easily rebuilt today:
Alternators, Generators, Starters, Water Pumps, Power Brake Boosters, Carburetors, Distributors, Brake Shoes, Master and Wheel Cylinders, Brake Calipers, Air Conditioning Compressors, Power Window Motors, Convertible Top Motors and Cylinders, Power Steering Pumps and Gearboxes, Wiper Motors, Motor and Trans Mounts., Fuel Pumps, Harmonic Balancers, Driveline Supports, Clutches and of course - Engines and Transmissions.

So if all else has failed, find a local or larger scale rebuilder either on your own or thru a parts store. DON'T SCRAP THE PART - if you have patience you can usually find someone to help.
