Oliver 88 pressurized radiator cap

4010 puller · May 28, 2022

I ordered a new radiator for my 88. The filler neck isnt
the same as the old one. Does anyone know a part
number for one at an auto parts store? Its bigger than a
jd 4020 one .

Where did you order it? Korves Oliver (.com) has them for $9.50. They're not pressurized. Take a look down inside. The overflow isn't in the neck, it stands up in the tank. It only leaks off if the coolant level gets higher than the top of the tube. If it had pressure, it would blow off all the time.

Yea its not that style one. The overflow is in the neck.its not the cap that says water on it, the bigger one

Doesn't sound like an 88 radiator unless I'm missing something. Korves has the pressurized caps too. Are those like what you need? I think they'd be for the three and four digits. Those have a smaller neck on them than the original 88 would have had.

Maybe someone replaced the radiator with a more modern one. Like Randy said, Korves has them. Korvesoliverdotcom.
