What clutch master cylinder fluid replacement interval on 1997 Jeep Wrangler?

There's no specific mileage or time interval for replacing the clutch master cylinder fluid in a 1997 Jeep Wrangler in the owner's manual. Instead, it's recommended to flush and bleed the clutch hydraulic system as needed. This is usually done when:

* The clutch feels spongy or weak: This indicates air in the system or low fluid level.

* The clutch pedal goes to the floor: This is a serious issue indicating a leak or complete failure.

* Routine maintenance: As part of a general brake system service (since the fluid is often the same), some mechanics recommend flushing the clutch system every 2-3 years or 30,000-40,000 miles, *especially if the vehicle is frequently off-road*. However, this is preventative, not mandated.

It's crucial to monitor the clutch's performance and address any issues promptly. Ignoring a problem can lead to clutch failure, requiring a much more expensive repair. Rather than following a strict schedule, rely on the condition of the clutch and the fluid's appearance (it should be clean and clear, not dark or contaminated).
