MkIII Supra Power Steering Mod

Thursday, July 3rd, 2008

Supra Power Steering ModPower steering reservoir on turbo mkIIIs is located in an unfortunate spot where not only is it exposed to hot air blown through the radiator, but also it is blocking the same air flow from moving though around the turbo and thus helping to cool it. Unlike previous years, Supra model years 1991 and 1992 had an improved “power steering cooler”, upgraded with cooling fins vs. just a bent pipe running in the nose of the car. Apparently there must have been an issue with power steering fluid temperature that prompted this fix. In an attempt to remedy this problem on “Project Black”, a power steering fluid reservoir was replaced with a plastic unit from another Toyota car and moved away from the original location. The new placement allows for better cooling for both the power steering fluid and the turbocharger.
