[mudassar.muzaffar]

Hi

I have 2013 landcruiser ZX , its driven 38 K
when do i need to change the steering oil, Height control oil ?

help appreciated

Changing the power steering oil every 30-50k would help longevity, and is a relatively simple process.

The AHC system requires proper service and can be dangerous given the high pressures involved. Use only the OEM Toyota fluid. Every 75-100k would be a reasonable interval IMO.

For both, cleanliness is important during the procedure.

Thanks for the quick reply.

With the AHC fluid change, is there any need to service the actuators also , is it part of the process or not ?
Do you have any recommendation for particular dealership as i normally get maintenance service done from Gulberg Toyota dealership. In my case its less than 40k km so i guess still time to go for it.

thanks in advance..

It depends on the use. Hard off roading requires more frequent service. A full bleeding at the accumulators and globes is usually not needed until high mileages given that the system is robust. An an interim measure, put the vehicle on low and siphon out as much of the AHC from the reservoir and refill with fresh fluid.. Cleanliness is all-important.
