So while part say the okay, some space entirely versus it, and also suggest substituting one because that the other just in an emergency. This is mainly due to the fact that larger quantities of the wrong systems can end up deteriorating and destroying the device parts. If the ATF may work for some time, it in the long run affects the pump and also gearbox seals. It was in the so late 70s or perhaps previously that it was for sure to usage ATF in the strength steering pump.

It’s because the cars then didn’t use any innovative or lightweight products in the construction. In fact, the power steering equipment of these cars were made making use of crude materials, making that safe with ATF. That the modern-day vehicles that are constructed using vulnerable parts and subtle engineering techniques that make it important to use just the specific products designed for them.

The dorn product might not meet the system’s details requirements, and also may it is in harmful come the vehicle. If it’s significantly safe to swap in instance of Ford and GM models, a swap can ruin a BMW, Mercedes Benz, Audi or Honda.

Difference in purpose

ATF is used an ext for cleaning and also friction when PSF is offered for lubrication and also to mitigate friction in between the strength steering parts. PSF additionally reduces too much temperature build-up, lubricates the steering pump and also gear unit and provides hydraulic push to the system parts.

Difference in colour and smell
