Folks I need to replace the oil cooler that mounts in front of my radiator on a 7040. Any suggestions where I could get one is appreciated and the part number.

Thanks

Are you talking about the "second" oil cooler for the Power Shift transmission?? which was connected by tee fittings at the bottom tank of the radiator ??

Isn’t the cooler in front of radiator for power steering

Early 7040/7060 Power Shift tractors had inadequate cooling of the transmission oil. A second oil cooler was placed ahead of the radiator and teed into the existing bottom radiator tank cooler plumbing. I didn't find it under 7040, but did find it under 7060 in AGCO Parts books. The second cooler is the same p/n (70266313) as the power steering cooler. So, whichever cooler ahead of the radiator is leaking, they are both the same part.
