Upgrade your Jeep Wrangler JL or Gladiator JT with an aluminum expansion tank built to withstand the toughest trails and daily driving. The stock plastic tanks in Wranglers are known for cracking and leaking at the seams. It is not a matter of if it will fail, but when. Replacing it with this TIG-welded aluminum tank ensures you are ready for your next adventure without worrying about coolant loss.--This coolant recovery tank increases fluid capacity over the factory design and features internal OEM-style baffling to prevent aeration and sloshing when your Jeep is off-camber or bouncing through rough terrain. The wrinkle black powder-coated finish not only adds corrosion resistance but also gives your engine bay a rugged, refined look. An easy-to-read sight glass replaces the factory dipstick, making fluid checks quick and straightforward.--Installation is simple and can be done before your next weekend trip, giving you peace of mind on and off the trail. Complete with a Mishimoto radiator cap and backed by our lifetime warranty, this aluminum expansion tank is the reliable upgrade every Wrangler and Gladiator owner needs.
