Where is the coolant drain plug on a 1994 Pontiac Trans sport?

The coolant drain plug on a 1994 Pontiac Trans Sport is located on the bottom of the engine block, typically near the passenger side. However, there's no single definitive location specified in service manuals. Its exact position can vary slightly depending on the specific engine (3.1L or 3.8L V6).

To find it:

1. Consult your owner's manual: This is the best place to start. Even if it doesn't show a picture, it might give a general area.

2. Look underneath the engine: With the vehicle on level ground, locate the engine block. The drain plug is usually a bolt or a plug, often near the lowest part of the block on the passenger side. It may be somewhat hidden behind other components.

3. Look for a low point: The drain plug will be at the lowest point of the cooling system on the block to ensure complete drainage.

4. Feel for a bolt or plug: Run your hand along the bottom of the engine block. Be careful not to burn yourself; the engine may be warm. The plug will likely be a slightly different texture than the rest of the engine block, and it might even have a small square head.

Important: Before draining any coolant, let the engine cool completely to avoid burns. Have a suitable container ready to catch the coolant, and be aware that it may be hot or corrosive. Dispose of used coolant properly according to local regulations.
