Thread: Power Steering pump

Tweet

Anyone run a remote resevoir pump on there bbc's? I'm thinking about it on my blazer because i'd like to run a cooler but my pump/resevoir is mounted on the block low. So i'm thinking it would back flow when not running and over flow it.

I'm pulling together a set up for the van but you are making it too hard. Just plumb a cooler into the return line from the pump and place it low in front of the radiator... Shouldn't be an issue.

i have a resvoir pump on the 548 came off a 1990 camaro .same pump as CV sells many nascar guys use them not very big. i have the tank on core support i would think a small stack plate cooler lower then the tank

The issue is that the pump mount is low on the block. It's lover than the lowest stop infront of the radiator...

Ya i went to the parts store yesterday and looked for that pump...$145 w/ core and that was for a remaned one!

You aren't going to have any problems with back flow. The system is closed and, once you get it bled, there is no place for the fluid to go. If the pump isn't running there is no flow. Put the cooler under the radiator if you think it is going to be a problem but it really isn't an issue...

Thats just a little to pricey for me, I'd hate to see the price of a brand new one. I can make something else work.

I was worried about level because it would run back down when not running and overflow the resevoir. I'll get a pic of where the cooler is located now @ lunch.

How would you go about doing that?

Here's a pic of where the cooler is now....

feed line low side of pump can ? just come off that with a flow check valve i am sure mcmaster car would have some thing ??? less i not thinking out this right ?? even if you do not do nothing and it works i am still not sure about the added volume of oil when it heats up you may need more head space in the tank so there no over flow ????? take the filler neck and add a fitting down close to the can part that covers the pump so if heats up you have a resaovor can but would have to be leve or lower then fitting in neck or add a riser to the filler neck so you have more head space

Like AstroRacer said, it's a closed loop. Unless you vent the cooler (have a leak) it's not going to flow other than from the pump. Now getting all the air burped out may be another issue - have not thought that one through, but it probably won't be a problem unless you get extreme on the level difference.

I was thinking about using an old pump/resevoir combo and drilling a hole in the res and having an over flow.

Lines..
Pump to steering box
Steering box to cooler
Cooler to pump
Pump to overflow high on the resevoir

The only thing i was worried about was that the top on the resevoir has a twist top on it not an acual thread top. It's just one that you put on and 1/4 turn. But i guess it does seal because if it doesn't it would be spewing all over right from the get go...

Not really. You can remove the cap to check the add fluid with the engine running, right? The reservoir simply keeps the suction of the pump flooded and is not under pressure. There's some splash there, but the reservoir is vented.

Got home & measured both the cooler and power steering pump. The bottom line of the cooler was @ 41" tall. The top of the power steering reservoir was 41" tall as well. I have room to move the cooler down between 2-3". I think I'm just gonna run th old pump & move the cooler down, then I wouldn't have any problem of over flow. Hopefully.....

Here's a better pic of the setup im running right now. Right now the cooler is being used for the trans but i have a new cooler for that. So i thought i'd use the old one for the power steering.
