Good News!
I just replaced the leaking (cracked) windshield washer reservoir tank on my 05 last week that has been leaking since I bought the Jeep and here is what I discovered!
After a lot of on line research, I learned that Autozone lists an OEM replacement reservoir for a 06 Liberty but not an 05.
On line research revealed that both 05 & 06 have the same OEM Chrysler part number (05161320AC), go figure why Autozone did not list one for an 05?
So, I ordered and purchased the one for the 06 (Autozone part no. Part Number: 603-314) for 41.99 and hoped it would be the same.
Mine has both front & rear washers and a level sensor!
Instructions to change:
Jacked the right front up and removed the RF wheel. Removed most of the plastic trees from the front section that hold the inner finder liner. Pulled the fender liner back to reveal the reservoir. Unplugged the level sensor and then popped the pump out of the tank and let it dangle on the hoses, removed two 6 mm bolts that were holding the tank to the Jeep. Up top removed the reservoir cap and lanyard, then removed the air box to grill connector.
Maneuvered the old tank out, compared it to the new tank, (Exactly the same as the old one, maybe even a little bit better looking quality wise), Removed the rubber grommets from the old one and installed them in the new one using a little Vaseline, then maneuvered the new tank in place and bolted it in place and re-installed the pump and connected the wire for the level sensor. Put everything back in place on top and filled the reservoir up and checked for leaks, had none!
Re-installed the RF wheel.
It is quite easy to change, swapped in out in less than 30 minutes total time start to finish! & < 50 bucks
