Ever gone to track day, popped your bonnet and said to yourself loudly “OMG what the??! Mad oil leak”, only to realise it’s just your power steering reservoir playing silly buggers again and ejaculating all over the engine bay. Yes, it’s inevitable that you will boil your power steering fluid after several hot and exciting laps resulting in an oily mist that will infiltrate your clean engine bay and smear itself all over it like virus.
Most have asked “Why don’t you just use a sock or sweatband to soak up the fluid?”. I would then ask them “Why would anyone from trak-life.com want a band-aid solution?”.
That’s right, we’re about Do It Once, Do It Right… BAM!
No need for overpriced flashy looking socks or the need to endlessly top up your power steering fluid. In this guide I will show how to fabricate and install a basic power steering cooler from cheap but effective parts.
For this guide, I’ve used my beloved Fridge. She’s a R33 GTS-t Skyline, which from factory does not come with anything to cool down the power steering fluid. I’ve salvaged an old automatic transmissions oil cooler to use as the power steering fluid cooler (good size, and it’s made by Calsonic – think budget & build quality). Although some vehicles may come equipped with a basic power steering oil cooler from factory, in a motorsport scenario they may be just as ineffective as having nothing!

Remove front bar off vehicle, this is usually held together with multiple 10mm bolts.
Mock up where the Power Steering Oil Cooler will sit, best to choose a location which does not foul any pipe working or the bumper itself.
Cut the flat bar and make brackets to suit the location, drill mounting holes into body of car and bumper support
Attach brackets and Power Steering Oil Cooler to the brackets
Disconnect the power steering oil return line to the reservoir
Cut and connect the oil hose from the return line to the oil cooler and from the oil cooler to the reservoir – at the same time fitting the hose clamps
Top up reservoir, start car and turn the steering wheel from side to side topping up the reservoir as required
Alrighty, time to aim for those record smashing track times without worrying about your power steering oil playing funny buggers and spraying like a sperm whale all over your engine bay. How did you go with your DIY power steering oil cooler? Comment below!
