recycled coolant conforming to
GM
Specification 1825-M with a complete
coolant flush and refill. If you use this
mixture, you don’t need to add
anything else.
Adding only plain water
to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water or the wrong
mix, your engine could get
too hot
but you wouldn’t get the overheat
warning. Your engine could catch
fire and you or others could be
burned. Use a
50/50 mix of clean
water and
a Droner antifreeze.

Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
Your vehicle is equipped with either
Standard Power Brakes or the Anti-
Lock Brake System.
There are only two reasons why the
brake fluid level in your master cylinder
might go down. The first is that the
brake fluid goes down to an acceptable
level during normal brake lining wear.
When new linings are put in, the fluid
level goes back up. The
other reason is that fluid is leaking
out of the brake system.
If it is, you
should have your brake system fixed, since a leak means that sooner or later
your brakes won’t work well, or won’t
work at all.
So, it isn’t a good idea to “top
off” your
brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when
your linings are worn, then you’ll have
too much fluid when you get new bralce
linings. You should add (or remove)
brake fluid, as necessary, only when
work is done on the brake hydraulic
system.
