I have a wagon with a L148 engine will this cap work?

Willys Jeep Parts Tech:
Send us a photo of your old cap so we can see it and confirm.

Gonna sound like a dumb question but.... Not sure what a "side mount" radiator is?? Will this fit my 56 CJ-5??

Willys Jeep Parts Tech:
Bolts directly to the sides of your grille.

I have a '48 sedan delivery wagon, side mount radiator. Inside of neck is 1" deep, and approximately 1 5/8" diameter. Is this part number 648360 the correct cap?

NJ Miller:
No, it will not seal the inner opening surface if the inside of the neck is 1". . The cap will only seal if the distance is 3/4. Also, a 4 lb cap is recommended.
Willys Jeep Parts Tech:
Yes, it should be the correct one. Thanks

Is this the right cap for a 51 CJ3A with a large radiator neck. I've crossed these numbers with may local parts store but all of them are to small.

Willys Jeep Parts Tech:
Yes, this should be the correct one as long as you have the side mount radiator. Thanks

I am having trouble finding a cap To fit my 1953 M38a1 Jeep. The caps I find at auto stores have been too small. Not sure if this is the original radiator. My cap measures 2 1/2 in between the tangs and 2 7/8 diameter. Your help would be appreciated.

Willys Jeep Parts Tech:
This should be the one. Please call us toll free and we can confirm with your radiator.
