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...Quote:

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.Quote:

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.Quote:

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...Quote:

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.

Just curious, why would you want to cool your power steering fluid? Not sure I've ever seen a need for that in the past.
actualy I had a 97 Jeep G/C that the power steering pump had a finned cooler right at the pump....But why I GOT NO IDEA.
big tires off road in mud = heat
Run your vehicle hard then stick ur finger into the reservoir & tell he if its hot? lol My reason is that I run a spool front and usually atleast 35" Boggers. Takes some extra steering to get around. I think of it as a tranny...it's stated to be cool than smoking hotQuote:

It sounds to me like you could use a steering assist cylinder. I know all to well how it is trying to turn a 4wd with a spool front and rear. Not real fun. HahaQuote:

Not in the budget as of right now, but yes that would help out a lot. I have lockouts right now so really the only time that it'll be hard steering is when it's in the mud!Quote:

i build engine s for off road guy s. i my self never had a offroad truck .but many of the guys use full hyd steering .stuff that shows up at the red neck yacht culb there nuts on some of them builds and what they do with them
Nope didnt make it this year, I was in the process of putting the front axle back together.Quote:

Well here's my take, I work on vehicles every day and there is lots of em that have power steering coolers,especially trucks and lots of chevy pickups with a low mounted pump such as yours. None of em have any thing special. Return line from gear box to cooler and from cooler to return side of pump/reservoir. Never seen a one of em over flow.
that may be so but then you add 35+ tall tires and go off road i would say all bets are off i seen guy s bust thing you would never think would fail seen parts weld them self together as well .guy walked in my shop with a pop bottle inside of it was a roller lifter and part of a 3/8 080 wall push rod smash/welded together from beating the last ounce of life out of that poor engine .them off road guys are a interesting buchQuote:

Shouldn't have any concerns with overflowing a reservoir the way the system works, no matter how hard you drive it or how big the tires get.Quote:
