Engine Coolant Flush:
Every 30,000 miles or 2 years.
Transmission Fluid Change:
Automatic: every 30,000-50,000 miles; Manual: every 50,000-100,000 miles. Consult manual for exact specification and procedure.
Spark Plug Replacement:
Varies by plug type (e.g., copper, platinum). Typically 30,000-60,000 miles. The 4.3L V6 often used 2 spark plugs per cylinder (12 total).

Coolant Type:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. GM specifies Dex-Cool for later models, but for '95, a universal green coolant is likely appropriate, though confirmation in the manual is key.
