2. Only when the engine is cool, remove
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.
3. Flush out the system with running
water.
4. Drain the system completely. Insert
and tighten the plug. Add as much
ethylene-glycol-based coolant and
water as necessary to provide freezing
and corrosion protection.
5. In extremely cold climates, add the
amount recommended in the coolant
manufacturer’s instructions.
6. Run the engine at idle with the cooling
system cap off. Slowly add additional
coolant if necessary.
7. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
8. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time.

Inspecting Brake/Clutch Fluid
Level
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
