power steering fluid cooler

Postby Hwy78Cruiser » Mon Feb 03, 2020 12:53 pm

My '66 Toro has a little radiator/cooler up in the grille area. It's hard to imagine power steering pump working so hard that it needs cooling, but there it is. My '64 Cutlass has what looks to be the same power steering pump, with no cooler.

My question, couched in the idea that "Toronados were highly engineered" (and I am an engineer) is: Is this cooler really needed?

I am doing a little re-configuring under the hood, including replacing the vacuum headlamp openers with electronic linear actuators (see separate topic), and I am thinking if eliminating the power steering fluid cooler.

Can anyone offer a compelling reason that I should keep that little power steering pump cooler?

You need to remember that your 66 Toro has MUCH more wieght over the front wheels than you cutlass. All of the load from the engine, trans, and axle is over the front tires, not to mention that the sheetmetal/bumpers on the toro are heavier. I would not remove the steering cooler. Also, despite what it looks like from the outside, the pump is most likely not the same. When I restored my 68 pump, the viens and associated parts were almost 1/4" deeper than any of the a body pumps I have. This means the toro pump will move more fluid per revolution than the a body pump. You are correct that the pumps look identical from the outside, but once you remove the guts from the pump housing, you may find that they are deeper/ thicker.

Very good insights, I will keep the cooler, thank you!

And my philosophy, also as an engineer, is that even if it's not absolutely necessary, it can't hurt.

What do they say about birds of a feather flocking together? I'm a civil engineer as well.

That's funny.

I quit my engineering job 7 months after I graduated from Ga Tech. I haven't done anything related to my degree since.
