2. Then keep turning the DMCM coolant surge tank

pressure cap slowly, and remove it.

3. Add the pre-mixed DEX-COOL™, available at your

dealer/retailer, to the DMCM coolant surge tank

until the level reaches the FULL COLD mark.

4. Turn the ignition to ON/RUN without starting the

engine. The hybrid cooling pumps will run and

any trapped air will purge to the surge tank.

5. Add the pre-mixed DEX-COOL™, available at your

dealer/retailer, until the coolant level is maintained at

the FULL COLD mark. This should take no longer

than two minutes of hybrid cooling pump operation.

If the level cannot be kept at the FULL COLD

level, your vehicle may need service. See your

dealer/retailer.

6. Then replace the

DMCM coolant surge

tank pressure cap.

Be sure the pressure

cap is hand-tight

and fully seated.

Notice: Using tap water, cooling system sealers or

conditioners in an attempt to stop coolant leaks

can damage the DMCM and engine cooling systems.

Never use tap water, cooling system sealers or

conditioners in your cooling system.
