Does it come with a cap

Since this tank does not have a fill line, how do I determine if I have enough coolant?


  • The tank is designed in which that the max fill on the tank is just below the cap zone, as long as it is to this level the vehicle will have the optimum amount of coolant.

    Finishes the engine bay.

    Well put together, goes well with the Moroso brake fluid reservoir cover and fuse box cover, painted all three flat black with high temp engine paint. Add a Moroso battery cover and a set of billet fluid caps and it dresses up the engine bay quite nicely. I was impressed with the weld quality on all the Moroso products, just another quality item offered by American Muscle.

    Now, when you pop the hood, all looks great

    The 1st time I popped the hood while I was just looking at the dealer, that ugly plastic tank was the thing that caught my eye. This tank gives the look that befits our cars. I primed and painted flat black which looks perfect. The finish is great and the welds are near perfect. I followed the install that was submitted here at AM and it was super easy. You'll be glad you got it.

    Aluminum Coolant Expansion Tank

    Extremely high quality product. Looks fantastic under the hood. I used the existing cap to cut down the bling bling. Its not chrome, rather it has a very purposeful matte finish with a little bit of a hand-built look. If you are into shiny jewelry, you should take a close look at the hand welding in the photos. I paid over $400 for a similar tank for my british motorcycle.

    Great Look

    Installation took under 30 minutes. Siphon coolant out of original tank into a container with small clear hose. Get hose part way down large hose. Clamp off small hoses using vice grips and remove. Install new tank. This tank really looks awesome under the hood.

    Great Product

    Took about 1/2 hour to install. Biggest challenge was draining the original coolant tank. Once original tank is drained takes all of about 10 minutes to swap out. Really made a huge difference in the overall look under the hood.

    This expansion tank really added looks and dependable service over the factory stock tank. Easy to install and I recommend the dress up tank cap cover to go with it.

    Awesome Touch To The Beautiful Coyote Motor

    I added the Moroso Expansion Tank to the engine bay more for the fact that my father was constantly telling me how much nicer the engine bay would look with aluminum accesories... After I received my Moroso expansion tank, I could not believe how great the quality and finish was... Instal was a breeze.. I also added the chrome engine knobs to match the expansion tank... I highly recommend this product... The quality alone speakes for itself

    I totally recommend this tank, easy to install,and gets rid of the plastic garbage of a tank that came from the factory,I powder coated mine black to go with everything else that i did under the hood & it looks sick,but either way painted or not its a sweet piece,so spend the money on it you will be happy you did,its well worth it.

    Excellent Quality

    I got the tank in two days gotta love American Muscle for quick ship all the time. Tank and the welds look great. I wanted it in black so I hit it with a scuff pad for 15 minutes and then degreaser/wax remover three times. Then I shot it with two coats of zinc etching primer followed by three coats of high temp (500 deg) black satin VHT paint. Ill let it cure for a week and install it this Friday but it looks like a million bucks and should match the rest of the blackout I did under the hood. Dave

    great looks

    Had the Moroso Coolant Expansion Tank installed when I did an engine flush. Replaced all of the radiator/cooling system hoses and thermostat at the same time, topped off the Moroso tank with a Roush Black Billet cap cover really added to the already cool engine dress-up items under the hood. The Moroso tank really looks great and OI was happy to get rid of the factory ugly coolant tank. Great buy from American Muscle great retailer! Installation was a breeze.

    A must for engine dress up! Get rid of the ugly plastic plastic expansion tank, especially on 2015 and newer where it looks like a plastic water bottle. Moroso tank is tig welded aluminum and looks great. On my 2014 I painted the tank with satin black engine ; it matches other billet aluminum dress up parts also painted black. I used a black billet aluminum cap for the tank. Only down side like anything billet aluminum it's quite expensive.
