To adjust it:
1. Locate the alternator: It's usually on the front of the engine, near the top.
2. Identify the adjustment: There's usually a tensioner pulley or a bolt (often with an eccentric cam or slotted hole) on the alternator bracket itself, or on a separate bracket supporting the alternator. This allows you to move the alternator slightly, thereby tightening or loosening the belt.
3. Loosen the tension: There will be a nut or bolt you need to loosen to allow movement of the alternator and thus the belt. A wrench of the appropriate size is required. *Consult a Volvo 240 workshop manual* or a repair guide specific to your car's year as the exact location and method may vary slightly.
4. Tighten the belt: Once the tension is loosened, you can adjust the position of the alternator (or tensioner pulley) to tighten the belt. The belt should have the proper tension where it doesn't feel overly loose (it will sag) but not too tight (it could make the alternator bearings wear prematurely).
5. Tighten the adjustment bolt/nut: Once the correct tension is achieved, tighten the nut or bolt which controls the alternator position securely.
6. Check belt alignment: Ensure the belt runs correctly in the grooves of all pulleys.
Regarding power steering: You should not need to disassemble the power steering system to adjust the condenser fan belt. The power steering pump and its belt are usually on a separate belt system. However, there is some proximity to the alternator so be cautious when working in this area.
Important Considerations:
* Workshop Manual: A Volvo 240 workshop manual is highly recommended for detailed diagrams and specific instructions for your car's model year. This will greatly improve the safety and efficiency of the repair.
* Safety: Disconnect the negative battery terminal before working on the belt.
* Tools: You'll need the correct wrenches to loosen and tighten the alternator adjustment bolt/nut.
If you are not comfortable working on your car, it's always best to take it to a qualified mechanic. Improper belt tension can lead to premature wear of components, belt failure, or other issues.
