However, I can provide some general guidance:
* Location: Idler pulleys are typically found on the front of the engine, near the serpentine belt. You might find them:
* Attached to the engine block: Look for a small pulley with a bearing that spins freely.
* Mounted on a bracket: The bracket itself will be attached to the engine block, with the idler pulley mounted on it.
* Appearance:
* Small pulley: Usually 2-3 inches in diameter.
* Bearing: Has a smooth, round surface with a small, central hole for the belt to run over.
* Metal construction: Often made of aluminum or steel.
To find the idler pulley on your specific Wrangler:
1. Identify your engine code: Check your engine compartment for a sticker or tag that lists the engine code (e.g., 2.5L). This will help you narrow down the possibilities.
2. Consult a repair manual: Find a repair manual specific to your 1990 Jeep Wrangler and its engine code. The manual will have diagrams showing the belt routing and the location of all pulleys, including the idler pulley.
3. Visual inspection: If you have access to the engine compartment, you can look for a small pulley that seems to be separate from other pulleys attached to the engine. This is likely the idler pulley.
Remember: Safety first! Always wear eye protection and gloves when working around engine components. If you are unsure about identifying the idler pulley or doing any work on your Wrangler, it's best to consult a qualified mechanic.
