I am getting ready to replace, with new OER parts, the power steering pump/reservoir and PS control valve in a 1964 Impala SS with the original 409/340 hp engine.

Do any of you happen to know the fluid capacity of the PS system for this vehicle? I'm thinking around a quart, but I'm not sure.

I'm also planning on using a full synthetic Prestone product for America cars. Any other suggestions for me?

Thanks much!

Don't use Power Steering Fluid, it isn't viscous enough. That is what the shop put into my '62 when they put the rebuilt engine back in, and the steering didn't work very well. I told them to use Dextron, and all was back to normal. No need for synthetic either..

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

I agree with junky. I have tried several power steering fluids on my 62 and 63 factory power steering systems. The cars of that era came with ATF in the system and I too have found that it works better than power steering fluid.

Use Dexron III Automatic Transmission Fluid (ATF). Do not use Dexron VI synthetic fluid. Don't use ANY kind of synthetic fluid in your power steering system.
