BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
Let me start by giving you the fluid types.
All vehicles covered herein use Automatic Transmission Fluid (ATF) as the power steering fluid. Use DEXRON® III type ATF
.BMW recommends that the coolant be changed every 2 years. BMW recommends that an ethylene glycol based antifreeze coolant be used. Stay with a name brand that is compatible with aluminum and is nitrate and amino free. The coolant should be a 50/50 mix with distilled water to achieve protection to minus 35°F. (minus 31°C.). The concentration should not exceed 60% as this will actually reduce the effectiveness of the fluid as a heat transfer medium and could cause deterioration of coolant passage seals. Using distilled water instead of tap water will also help in the prevention of cooling system deposits.
All vehicles with DSC without pre charging pumps must be filled with the new DOT4 low-viscosity brake fluid! All other models can be filled with the DOT4 or DOT4 low viscosity brake fluid.
All current models / engines from 1999 model year with extended oil change intervals of approximately 15,000 miles BMW High Performance Synthetic Oil SAE 5W-30EXCEPTIONS BMW recommends the use of BMW High Performance Synthetic Oil SAE 5W-30 or Castrol RS SAE 10W-60 Synthetic Oil also called Castrol TWS Motorsport SAE 10W-60 Synthetic Oil on all models as outlined below whenever a service is necessary to avoid engine damage.Model / EngineE60 M5 / S85 From 9/2005: Castrol TWS Motorsport SAE 10W-60 Synthetic OilE63 / S85 From 3/2006: Castrol TWS Motorsport SAE 10W-60 Synthetic OilE39 M5 / S62 Up to 3/2000: Castrol RS SAE 10W-60 Synthetic Oil also called Castrol TWS Motorsport SAE 10W-60 Synthetic OilNote: The M5 up to 3/00 production requires a specially formulated synthetic engine oil - Castrol Formula RS SAE 10w-60 or Castrol TWS Motorsport SAE 10W-60 is the only oil approved for this engine.

The specified oil must be used to avoid engine damage.
I will send pictures in the next post.
This looks very helpful - if the pictures will show me exactly where to put the fluids. The car is a mystery to me under the hood. The only thing I can identify is the oil resevoir...
I appreciate your expertise. Should I hit accept to pay you for your answer and get pics of where things go?
The power steering fluid dipstick is part of the cap on the reservoir
View of the power steering and self leveling system hydraulic fluid reservoir
The fluid level should be between the minimum and maximum level marks
The power steering fluid reservoir is located on the left side of the engine toward the front. On E36 models, it may be necessary to remove the air filter housing to access the reservoir.
Stop the engine and remove the cap/dipstick from the power steering reservoir. The dipstick is part of the reservoir cap and is removed by turning the cap counterclockwise. Wipe the filler cap from debris before removing the cap, then remove and wipe the dipstick and replace in the reservoir. Remove the cap and check the level. Check that the level is between the marks on the dipstick and add fluid as necessary. Run the engine and recheck the fluid level. With the engine not running, the fluid level may rise above the marks on the dipstick, but this is normal.
The coolant expansion tank is translucent, which makes checking the fluid level easy The integral coolant expansion tank is also translucent for easy level checks The bleeder is located next to radiator cap. Check the radiator cap gaskets when removed
BMW vehicles are equipped with translucent coolant expansion tanks. There will be marks indicating "MAX" and/or "COLD" levels. There is no need to remove the fill cap from the expansion tank to check the fluid level. Do not remove the fill cap unless coolant needs to be added to the system.
Here is a diagram of the under hood, (m50) yours shoudl be similar to it.
The brake fluid will go in a resivoir that looks like this one,
You might be able to see if it's full without taking the cap off, (its sort of see through) Sorry I don't have a better picture in my data base. OH..here is one
The fluid reservoir is installed directly onto the brake master cylinder
hmm - my car doesn't look like these pics. my coolant is on the left near # XXXXX on your pics. it is a black tank and has a yellow min/max tab inside. my oil is just to the right of that but still on the left of the engine cover/block. the dipstick for my oil is just to the right of the center near the cockpit.
I don't know where the power steering and brake fluid resevoirs are - but there are no tranparent resevoirs that i can see
The brake fluid resivoir will be on the master cylinder, at fire wall, directly in front of the driver, under the hood.
The power steeirng resivoir will either look like this one
OR this one, where you would have to remove the nut on the cover
