Our take on the Weapon R Aluminum Coolant Overflow Tank Black 24 oz Capacity

The Weapon R Aluminum Coolant Overflow Tank is a 24 oz catch can that replaces a factory plastic coolant reservoir. It is TIG welded from 6061 aluminum with billet machined fittings, polished to a show finish, and mounts to stock bolt holes without drilling. It suits owners of older cars whose plastic tanks have gone yellow or cracked, and track drivers who want overflow contained. Against generic universal cans, the vehicle-specific bracket and included tubing and clamps make install simpler, but it is a cosmetic and durability upgrade, not a performance part.

Questions and answers

Does it fit my car without drilling?
It is application-specific and uses the stock bolt holes on the vehicles it is listed for. Check the fitment for your model before ordering.
How much coolant does it hold?
24 oz. That covers normal expansion overflow, but it is smaller than many factory plastic tanks.
What is in the box?
The tank, an aluminum mounting bracket, 3 feet of clear reinforced tubing and stainless steel hose clamps.
Is it a direct replacement for the factory tank?
It replaces the factory catch/overflow reservoir and connects with the supplied tubing. It is a catch tank, not a pressurized part of the cooling system.
Will the polished finish hold up?
The aluminum is polished and TIG welded, so it resists cracking and discoloring like plastic. It can dull over time and benefits from occasional polishing.
Can I check the coolant level?
There is no sight tube or window on the tank, so you check level by looking inside the filler or by how much fluid drains when you empty it.
