New Project 68 Impala

Hey guys, I am a college student from Sydney Australia, just bought a project 68 Impala fastback 327 small block. Have a few basic questions i'm struggling to get answers to. Where is the power steering reservoir located? and what fluid should I use? also the steering siezed up so I am hoping it's out of fluid, Also what oil should i be using 10W-30?. and What transmission fluid should I use?, It's equipped with the 2 speed powerglide. Also just normal green coolant be ok?. Thanks for your time, I will be covering the restoration on this forum and hope to make some new friends.

There is really no secret formula to the older vehicles. The power steering reservoir is attached to the power steering pulley. Should have a small black twist off cap. As far as the other fluids go, just get Trans fluid that is compatible with GM cars and 10W 30 is fine for you vehicle.

Welcome to the Team Mack!

Here is a picture of a couple of power steering pumps. The reservoir was a tank with the pump inside.

It uses a special anti-foaming hydraulic fluid available at most autoparts stores.

The transmission fluid should be Dextron III - Ford ATF, but be very careful not to over fill ther transmissions oil pan or you will blow the seals and create a massive leaks.

Motor oil should be petroleum based and not synthetic. You choose the weight of the oil to match your ambient air temperature (seasonally not daily). The higher the outside temp the higher the last number should be. You should install an oil pressure gauge where you can keep an eye on it. A tired engine with worn bearings will not like a thin oil (small viscosity number) as it needs oil pressure to maintain an oil film over the bearing surface.

As to to your steering being frozen it ios probably a problem in the steering gear box. It has a lubricant that is not refillable. If it gums up the ball bearings inside will not roll and it will not turn. You can buy a replacement steering gear box on line or take one off another Chevy as they all interchange. The newer the box the more road feel you will get as the one in your car gives no feed back what-so-ever.
