I just changed out T stat, how much coolant should I put in this tank before I start burping process at the crossover? (2003 Mach 1)...thanks.

Deerslayer

  • When refilling the cooling system manually, you should keep the system between the min/max markings to ensure an overflow does not occur, and a low coolant situation does not occur. Make sure to observe and maintain this coolant level. If available, a vacuum coolant fill will eliminate the need for burping the cooling system, allowing the fill to be a one step process, and ensuring no air remains in the system.

I know you take the fluid out of the old tank prior to removing it. Once you install the new tank and it is refilled, do you need to burp the coolant system now since you broke lines?

AaronS

  • When installing the Moroso Aluminum Coolant Expansion Tank you should burp or bleed the cooling system, unless the system was vacuum filled. This will prevent air pockets in the system which can cause issues.

Does this have a high polish finish to it or just a brushed one?

DustinD

  • The Moroso Aluminum Coolant Expansion Tank comes in a brushed finished, however, it can be polished if desired.

how do you know where to stop filling is it at the top of the cap just wondering because there isn't one already on my car and I don't know where to start filling it

Irishmen

  • Hello! For this, yes you will start filling it through the cap on the expansion tank. I would fill it about halfway up the tank. This expansion tank is for when the coolant expands it can overflow into this tank instead of on the ground, so leave so room for excess coolant in the tank.

    I installed this on my 97GT and now my hood won't close properly. I don't think I did anything wrong I unhooked my old one and replaced the new one in the same spot. I need a cowl hood now. It looks GREAT under the hood next to my supercharger. It sticks up higher and holds more coolant than the oem

    Good looking tank. I have a Cobra so dont need a level sensor. Install no problem, even over my thick Mishimoto radiator. Its heavier than stock of course, and you cant see the coolant level, which is a problem.

    Great fit. Nice looks.

    This coolant tank mounted up perfectly and looks great. The single drawback to this piece is there is no plug or tap for the coolant sensor. Other than that i love it. AM muscle was fast with delivery and their service is great!

    Great Qualiry no sensor

    This is definitely an upgrade from the stock piece however you do have to give up the sensor that tells you when you are low on coolant but well worth it

    a great product

    The tank quality and appearance is amazing. Does not have the structural weakness the stock plastic tank does so guaranteed no leaks. Hood clearance is a stock fit but the bottom of the tank does hit the stock fan shroud. Im going to a slim fan so doesnt bother me. All in all its a great product.

    Beautiful, high-quality tank. Impressive welds

    I bought this to replace my worn, cracked factory expansion tank and I couldn't be happier with the results. This tank is a very simple installation that will take you about 30 minutes with a few simple hand tools. The tank looks absolutely gorgeous and has some very nice welds. Once installed, this tank is sure to get some attention. The tank does not include new hardware, so I would recommend getting some stainless steel nuts to keep everything looking clean. This tank does not include a radiator cap and the factory one doesn't look very good installed so I ordered a billet one. There is no spot on this tank for the coolant level sensor, so be sure to just unplug it and tie it up somewhere. I see a lot of people complaining about that but to be honest, if you don't check your fluids that often or go under the hood modding that often, why are you buying something like this in the first place? Overall, this tank fits perfectly and looks stunning. A must have if you're looking to clean up under the hood and this tank holds up well to heat if you've got some serious mods.

    Great product

    I really like this product. Installation was very simple, and fitment was great. No coolant level sensor in my 04 cobra, so that was a non issue for me. My only request is for moroso to design a stock size cap that doesn't look like the stock one. Thanks for a great product.

    Haven't installed yet, but welds look great. The piece itself looks very well built. HIGHLY RECOMMEND!! NOTE: No cap included. Use factory cap or just pick up a new one for a couple bucks (that's what I did).

    Looks solid.

    Bought this because my plastic one from 2001 got brittle and cracked when I was swapping my motor. I really like this peice. It's solid, good welds and looks really nice. There are complaints about the spot for the sensor, but I didn't have a sensor and it made no difference.

    Combined with the radiator cover this looks excellent! Although the only down side it doesn't have a spot to put the coolant level sensor in. That would of been good to know, but still wouldn't affect my decision and i would get it. It has good quality welds too.
