To find the reservoir:
1. Locate the clutch master cylinder. This is typically found on the firewall, near the brake master cylinder, but sometimes slightly lower or offset. It'll be a cylindrical component with a hydraulic line leading away from it towards the clutch slave cylinder.
2. Look for a reservoir cap. The reservoir will have a cap, often plastic, that can be removed for checking and adding fluid. The cap may be marked with a clutch symbol or have a label indicating "Clutch Fluid" or similar.
Important Notes:
* Low Fluid is a Symptom, Not the Problem: Having to pump the clutch to engage it usually indicates a leak in the system (in the master cylinder, slave cylinder, or lines) or a failing master or slave cylinder. Simply topping off the fluid will only provide a temporary fix. You must find and repair the leak.
* Type of Fluid: Use the correct type of clutch fluid specified in your Jeep's owner's manual. It's usually DOT 3 or DOT 4 brake fluid, but check your manual to be sure. Using the wrong fluid can damage your system.
* Bleeding the System: After addressing a leak, you'll likely need to bleed the clutch hydraulic system to remove air bubbles. This usually requires two people.
* Safety: Work in a well-ventilated area when handling brake/clutch fluid. It's corrosive and can damage paint.
If you're not comfortable working on your vehicle's hydraulic systems, it's best to take it to a qualified mechanic. Ignoring a clutch problem could lead to a complete clutch failure, leaving you unable to drive.
