power steering cooler opinions

[neverendingproject]

Im putting on a power steering cooler, and I have a predicament. I have hydroboost too and im wondering if I should have the hydroboost feed into the cooler, the power steering feed into the cooler or figure a ways to splice them and hook them both up. Both coming from the low pressure side of course. My thinking is that Hydroboost will only flow when I have the brakes on. Is this true?

I went with the nekkid option also. But I would probably go with power steering feeding into it. I would guess it circulates/flows around more than the hydro side. Thats where I would guess more heat is coming from? But I don't know anything on the hydroboost setup.

I think power steering gets more of a workout when wheelin....

I too have hydrboost. Last year - before I had a cooler - I lost my p/s pump on a trail. Not fun. We installed the new one at the campsite. When we flushed the lines the power steering return flowed fluid from the get-go, but the brake booster only flowed when applying brakes.

So I plumbed my cooler on the p/s return line only.

On an aside, I wouldn't tee the returns together through the cooler. When I first installed my serpentine belt setup I used a standard pump and reservoir with one return. I felt like the the returns teed together there was a slight lag in the steering. Especiallywith brakes applied coincidently enough. Don't notice it happening now with the 2 returns.

IIRC the high pressure line runs from the pump to the booster, and the then one low pressure hose runs from the booster to the reservoir and the high pressure hose runs from the booster to the steering box, then another low pressure hose runs from the box to the reservoir. I installed one in my trail rig and put it between the PS return and reservoir, and I believe thats how they are installed on factory equiped trucks.

You've got it right.

I'm thinking about adding a PS cooler to my 90 Blazer. I'm wondering what type of cooler you guys used and were did you mount it. Doesn't the cooler have to be mounted lower that the PS pump to prevent all the fluid from flowing back into the pump reservoir?

I'm running a stock cooler from a 91 suburban for now, however I am about to start searching for an m998 military hummer cooler. Its big enough to run hydr boost, hyd clutch fan and p/s with 37's. Should work fine for us.

I pulled the oil cooler, trans cooler and power steering cooler of a mid 90's one ton truck.
