PAHRZTEK Engine Coolant Reservoir Tank for Jeep Wrangler JL 2018-2024 V6 3.6L / 3.0L Diesel — Pre-Installed Cap, OE Fit

PAHRZTEK's Engine Coolant Reservoir Tank with pre-installed cap is a direct OE-fit replacement for Jeep Wrangler JL 2018–2024 V6 3.6L and 3.0L diesel models, restoring coolant capacity and leak-free operation.

If your Wrangler shows low coolant, visible reservoir cracks, or frequent topping up, a worn expansion tank is often the cause. This PAHRZTEK replacement tank matches OEM mounting points and sealing dimensions (replaces part #68283565AB / CH3014196) so you can swap the old bottle for a new one without cutting, drilling, or additional parts. Built from heat-resistant plastic and supplied with a pre-installed cap, it’s intended to resist under-hood thermal stress and reduce common overflow or evaporation problems associated with aging reservoirs.

How does this tank fit my 2018–2024 Jeep Wrangler JL?

The PAHRZTEK reservoir is engineered to the same form and function as the original equipment part it replaces. It uses the factory mounting points, hose connections, and cap sealing profile so installation is straightforward and reliable.

• Compatible with JL Wrangler V6 3.6L and 3.0L diesel 2018–2024 model years
• Direct replacement for OEM part numbers 68283565AB and CH3014196
• No modifications, drilling, or special tools required for a standard swap

Will this prevent coolant leaks and overheating symptoms?

Replacing a cracked or degraded expansion tank can stop coolant loss and the symptoms that follow, such as frequent low-coolant warnings or localized overheating. PAHRZTEK uses premium-grade, heat-resistant plastic designed for repeated thermal cycling to reduce the risk of cracks and evaporation compared with aged or brittle bottles.

• Heat-resistant construction helps resist deformation under engine temperatures
• Precision-fit cap and seals minimize leak paths and vapor loss
• Supplied as a complete assembly to eliminate missing-piece issues

How simple is the installation process for a DIYer or mechanic?

Installation is intended to be plug-and-play: the reservoir comes pre-assembled with the cap installed, and it follows OEM layout so it mounts into the original location. A basic toolkit and common garage experience are typically all that’s required to complete the swap in minimal time.

• Pre-installed cap and factory-style fittings reduce assembly steps
• Mounts to existing brackets and connects to the original hoses
• Designed to save labor time compared with sourcing parts or adapters

What comes in the box and what should I check after installation?

The package includes one PAHRZTEK coolant reservoir tank with a pre-installed reservoir cap for a complete replacement. After installation, verify hose clamps, fluid level, and system pressure per the vehicle manufacturer’s guidelines to ensure a proper seal and operation.

• Includes: 1 x coolant reservoir tank and 1 x pre-installed reservoir cap
• Recommended: refill with correct coolant type and bleed the system of air
• Post-install check: inspect for leaks with the engine at operating temperature
