DESCRIPTION
Forever fix the risk of your Fiat's motor overheating because of a stock plastic expansion tank failure. This overflow tank is a pressurized critical part of the cooling system and if the original plastic version fails you can have the motor quickly destroyed with overheating, often before the driver has a chance to notice the temp gauge spiking upwards. This all metal tank prevents that potentially very expensive failure and lasts a lifetime.
Direct replacement for your factory plastic coolant expansion tank. Made in the USA, all aluminum with beautiful TIG welding. Constructed with internal baffles and a machined aluminum neck that takes the factory caps. All of the inlets and outlets are positioned to match up with the factory hoses. The tank mounts to the same location as the factory tank and is built with the same dimensions for an easy fit.
OPTIONAL Cap:
Option is to add a high performance CSF 20 psi radiator cap for the pressurized side of the tank. These tanks are compatible with the factory radiator cap on the pressurized side, so replacing the cap is not mandatory, but if you need a replacement for your used factory cap then this is the best option, and higher pressure than the factory cap. A true high performance cap to match your high performance expansion tank. Note: the low pressure side of this tank takes the factory snap-on plastic cap, and we do not offer a replacement for that cap. With this option you are just getting a CSF high pressure radiator cap for the pressurized side of the tank, you will still reuse your factory plastic cap on the low pressure side.
Optional satin black powdercoated finish offers a more subtle option than the bare aluminum. The satin black is a low-gloss finish that looks right at home in the Fiat's engine bay
Stock plastic tanks are ticking time bombs due to the close proximity to the turbo so they see extreme temperatures, and as the plastic ages from heat cycles they crack and when they crack the coolant pressure is lost and the motor overheats. We decided it was time for a "lifetime" solution. This tank is the solution. It will not fail over time like the factory tank, and looks great as well!
Installation NOTES:
CLAMPS: While the factory squeeze-clamps on the hoses can be re-used, they get weaker the more they are removed/installed and having a tight seal on all the hoses is important since this tank is pressurized. We recommend changing the squeeze clamps out for worm drive hose clamps which can be found at any auto parts store.
CAP: You might need to very slightly adjust the 'tangs' on the factory radiator cap to fit the new metal neck with same tension as it did on the factory softer plastic neck, takes a few seconds to do with pair of needle nose pliers.
