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?
