Chevrolet 2005 Automobile User Manual


 
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
1. You can remove the fill neck pressure cap when
the intercooler system, including the upper
intercooler hose, is no longer hot. Turn the pressure
cap slowly counterclockwise about one-quarter of
a turn. If you hear a hiss, wait for that to stop. This
will allow any remaining pressure to be vented.
2. Then keep turning the pressure cap slowly, and
remove it.
3. Add the proper DEX-COOL
®
coolant mixture to the
fill neck, until there is coolant visible in the horizontal
tube section of the fill neck.
4. With the fill neck pressure cap off, start the engine
and let it run for at least 30 seconds. Watch out for
the engine cooling fan. Turn the engine off. By
this time, the coolant level inside the fill neck may
be lower. If the level drops so that coolant is
no longer visible in the horizontal tube section of
the fill neck, add more of the DEX-COOL
®
coolant
mixture to the fill neck until the level is again
visible in the horizontal tube section.
5. Replace the intercooler system pressure cap. Be
sure the pressure cap is hand-tight.
If the coolant is not at the proper level when the
system cools down again, see your dealer.
