The new power steering cooler is working well. There are no leaks with the new hoses, fittings and clamps. After a typical drive on suburban streets the cooler is warm but cool enough to be held in the hand without burning (sorry no definitive temperature measurements at the moment). Here’s a picture of it installed where it will get plenty of air flow.
A recent inspection on a Holden Commodore revealed that the power steering cooler was leaking. The standard cooler is a length of 3/8″ steel tube running horizontally in front of the radiator. These are known for rusting and splitting or leaking fluid. Below is a close up of the part that was removed.
