very slow water leak?
I recently bought a 1995 bmw 540i and have done a few things to bring it back to par.
However, I have been having to add some Prestone 50/50 to cap off the fluid. It is such
a small amount each few times I drive it in the very hot Oklahoma summer that I have
not been too worried about driving it. I watch the temperature gauge closely and it
never gets hot. The add coolant light comes on every few days. Since this is my first
BMW of any vintage I would like to know if this is normal or should I take it in for a
system pressure check to find where the fluid is going or should I wait for the fluid loss
to get worse so I can determine for myself a needed repair. This may sound silly but I
fear sometimes that a repair shop may find a minor problem but tell me I need some
major work. I feel if I wait the fluid loss will become apparent. I am not the least
mechanical and am a pessimist when it comes to auto repair shops. Is there an easy
way for me to determine such small amounts of fluid loss?
