* Engine Variations: Subaru engines from that era have various models. The location and appearance of the bleeder screw can vary between models.
* Visual Description Limitations: It's difficult to accurately describe a specific part just with words. A picture would be much more helpful.
How to Find Your Bleeder Screw:
1. Consult Your Owner's Manual: The manual should provide diagrams and instructions for locating and using the bleeder screw.
2. Look Online: Search for "1990 Subaru [your specific model] coolant bleeder screw" online. You might find diagrams or forum discussions.
3. Consult a Mechanic: If you're unsure, a mechanic familiar with Subarus can easily point out the bleeder screw for you.
General Tips:
* The bleeder screw is usually a small, hexagonal-shaped bolt located on the highest point of the cooling system, often on the radiator or thermostat housing.
* It might be made of metal or plastic.
* Look for a screw with a small hole or a slot in the center to allow air to escape.
Remember, working with coolant can be messy and require careful handling. If you're not comfortable doing it yourself, a mechanic is always the safest option.
