If your 80 Series Land Cruiser (1990–1997 models) is leaking coolant into the passenger-side cabin floor from the rear/under-seat heat exchanger (coolant-to-air unit), this kit makes the delete clean and professional.
The factory rear heater setup routes coolant under the passenger seat, and when the core fails (a common issue over time), it dumps coolant inside—soggy carpet, musty smell, potential mold, and endless headaches. Many owners delete it entirely for reliability, especially on overland/trail rigs or in warmer climates where rear heat isn't needed.
This kit includes:
- Precision plugs/caps for the 14mm coolant hoses (blocks flow after bypass/delete)
- Cover/patch panel to neatly seal and finish the open area in the cabin floor after removing the heat exchanger
Key Benefits:
- Eliminates interior coolant leaks and prevents future failures
- Cleaner, drier cabin—no more wet carpet or odors
- Simplifies coolant system (fewer failure points)
- Great for performance builds, overlanding, or daily drivers in mild climates
- Easy DIY install: Drain coolant, remove the under-seat exchanger, plug the hoses, install the floor cover (a few hours with basic tools)
Compatibility: Fits Toyota Land Cruiser 80 Series (including USDM FJ80/FZJ80, JDM/HDJ80 variants, and Lexus LX450) with the factory under-passenger-seat rear heater core setup. Confirm your routing if modified.
