Coolant requirements.
Coolant requirements.
Hi all,
My coolant low warning light (yellow) is coming on during startup and then goes away after a few minutes. I assume this means it is low and until pressure builds up the sensor is illuminated.
What kind of coolant is best to add to BMWs or does it differ between models? I assume the coolant is supposed to be mixed 50/50 with distilled water?

I agree with Jeff. also carefully inspect for leaks. especially around the expansion tank as they are notorious failure points on M52TU and M54 engines and you don't want it to crack and leak all the coolant and leave you stranded

Right. The M54 also should have a level indicator when you open the expansion tank. Do this cold and fill until the float indicator reads full. Run the car and then in a couple days when it's cold recheck the levels. Agree with Brent...check for leaks these are notorious.
How many miles on the engine? Its recommended that you do the water pump and thermostat at 60K. Also a known failure point.

personally I only use distilled... my water here is so hard (maybe I should say my minerals are so liquidy?) that putting it anywhere creates mineral deposits so it's not going in my cars

Here's another vote for distilled or deionized water. Distilled is probably easier to find as Shop-Rite has it in gallon containers.
When doing cooling-system service, be sure to remove the block-drain plug. If you don't do this, you will only drain about half of the system.
Also, be sure to replace the sealing ring on the block drain.
