Some Service and Pre-Delivery Tips
Aveo PDI service bulletin 03-00-89-040 explains several unique product
features. The information is useful for all technicians, not just the PDI
technician. Here are some highlights.
Coolant -- The Aveo cooling system is factory filled with blue
silicate/hybrid coolant (fig. 18) and will be serviced with traditional
green coolant. This type of coolant must be drained, flushed and refilled
every 30,000 miles (48,000 km). Use P/N 12378560 (1 gal). In Canada, use P/N
993088 (1L) or P/N 993089 (4L).
I thought that since GM developed Dex-Cool they'd use it rather then
traditional green...any ideas?
I noticed this too, while browsing through some of the
Daewoo vehicle manuals. Probably because the vehicle
has simply been rebadged, I imagine they have left the
choice of coolant up to the original manufacturer and
design engineers. It's certainly good to know, as we
will be doing maintence work on them within a few
I guess that makes sense, but since GM bought Daewoo couldn't they have them
put Dex-Cool or traditional anti-freeze? I can already see people going to a
store to get some more anti-freeze and confusing themselves and the clerks.
May have something to do with the communist government only allowing GM to
buy this particular type of antifreeze for thier production....That is if
Korea is still a communist nation...don't remember or care to look it up at
some quick recent world event updates. there are 2 koreas, north and south.
the south one has a large american presence to keep the nuclear threat,
communist north korea in check. the south is very friendly to the states.
the two are still officially at war, since no peace treaty has been signed,
but no shots have been fired between both sides for a few decades.
daewoo is from south korea, and like the states a capitalist democratic
nation. trading with the north would be as disallowed as trading with cuba.
as for the subject of antifreeze, the original daewoo was probably designed
for green coolant, so the changeover to dex-cool would not have been
properly engineered. this means that there are differences between the 2
systems other than the coolant itself, such as seals and fittings, and maybe
even rad sizing.

Whats a Aveo? Oh daewoo... Hey Saturn refuses to use dexcool and
synthetic oil. I think it had something to do with the fact that they
dont want people trying to go with long intervals between fluid changes.
Saturn used to use all their own engine designs, but the Ion as well as some
of the Vue and L-series use the same Ecotec 2.2L engine as in numerous other
GM vehicles, so there is no reason for them to have different coolant
