  • Power Steering Cooler - Why?

    Does anyone know why there are power steering coolers on our cars. For some reason does the p/s fluid get that hot where as it needs to be cooled or is it the opposite, where it needs to be warmed up for optimal performance?

    I would like to eliminate from my build but .......

    Thanx!

    Doesnt get to hot unless your doing road course stuff or Auto-X. Only SS and Certain TA's got them. Dont have one, never had the need, maybe if I get in to road course stuff or something.

          Not true. In fact, the stock 98-99 SS/WS6 and 2000+ LS1 power steering cooler is absolute junk and its limitations can definitely be seen on even a short autocross course. Do it a couple times and you'll start boiling the power steering fluid. Do it constantly and you risk melting the seals in the pump. GM's bandaid of bringing the fluid temperature down to the temp of the coolant is a friggin joke. They should of gone all the way and installed an external air cooled radiator. Also, the pump is to blame as well since it saps a pretty nasty amount of horsepower (relative to power steering pumps in general) due to high friction (which in turn creates the heat).

          Here's the solution to the problem (this and a large ambient temperature cooler):
