Caution on what to put in the LX470 automatic height adjustment system. Dealer said unless correct fluid is put in the system the seals may fail. Specifically warned against break fluid. Cost to repair is over $3,000. I bought a can of the fluid at the Lexus dealer for about $26. The can was approx. 1/2 gallon.
The Lexus LX470 has an Automatic Height Control (AHC) system. Do not ever put anything else in the Suspension Fluid Reservoir unless it is from a Lexus Dealer (or Toyota Dealer that's knowledgeable on what you need). It is part number 08886-01805 it is 2.5 Liters and they will be able to look it up (silver box can it is labeled Toyota Suspension Fluid AHC). It is important that you emphasize Suspension Fluid for LX470 with AHC. It will be a very costly mistake to use the wrong fluid.

When bleeding the radiator i found coolant leaked into power steering reservoir how would this happen?
1. Not enough information and you have not identified the vehicle either.
2. Coolant cannot leak to the PS system. They are entirely separate systems and unconnected.
3. If you have an auto transmission then in some models there is a section of the radiator used for cooling the auto transmission hydraulic fluid . IF there is a breach in the radiator between the 2 sections then coolant can flow into the auto trans fluid and vice versa. If you find there is pink hydraulic fluid in the coolant when draining the radiator then it will be auto transmission fluid.
In that event you will need to replace the radiator and to have the auto trans serviced now or the transmission will fail if the hydraulic fluid has been contaminated.
have you checked all the engine fluids? (oil, coolant, trans fluid) low levels of these fluids may cause automatic shut-down to prevent damage to the engine or drive-train.also if the fuel is low enough most newer vehicles automatically shut down so as to prevent running the injectors dry. other than that check your fuses and warning lamps in the vehicle a lot of times that will give you a clue as to what's wrong
It may be the seals swelling as the fluid heats up from use. Are you using trans. fluid or the 'blue stuff' designed for hydraulic systems? I had a similar problem with my 1st plow truck, I found that spraying the seals at the shafts of the up/down piston and angle pistons seemed to help, although only for a while, requiring spraying every few driveways. Some fluids (trans.) can cause the seals to swell, although I can't recall what type. Unfortunately, to really fix this you probably need to drain the system again, and replace all the seals, and refill with the 'blue' fluid.
Power steering fluid is fairly generic. Buy a good quality brand. If the system is low, it has to be leaking somewhere. In that case use a good conditioner such as the one made by Lucas. It is the only brand name product I've ever used that has worked on a consistent basis. And, will not harm internal components.(sound like a salesman? I'm not!) No chemical will repair broken or severely worn parts, but seals can dry out and leak. Never use transmission oil in power steering. That used to be OK but is not now.
Need more info on what the trans is doing , or not doing. No chance that brake fluid cools or lubes your transmission. The only possible connection is that your clutch is hydraulic which would use brake fluid , but two totaly different systems. Does your clutch feel funny?
