New for 2015 are the Granatelli Motor Sports S550 Mustang Coolant Surge Tanks (Part # 510100-P for Polished and #510100-B for Black Wrinkle) for all 2.3 EcoBoost, 3.7 V6, Mustang GT and Shelby GT350. This Unique Design Eliminates the unsightly bubble tank delivered from the factory. The Granatelli hand built 6061-T6 reservoir is a simple remove and replace installation using all factory hardware, you don’t even loose a drop of original coolant. All factory hose connections as well as the radiator cap are a direct cross over making installation no more than 10 minutes. The eye sore now nicknamed the “grenade” by several on the internet won’t win you any trophies in the engine compartment. The Granatelli unique design mimics the same taper and angle of the OE engine cover giving it a true stylized look while increasing capacity. Well-Suited with ALL Aftermarket Air Intake Systems. Show quality finished in either Powder Coated Black, Satin, or Mirror like Polished! Many People are Unaware, as delivered from Ford the factory surge tank can spew coolant on to the road surface making it unsafe for racing conditions. If competitive racing is in your future, Granatelli offers Part # 510101-P and #510101-B with Integrated NHRA and SCCA legal 1-pint Catch Can and Drain Petcock.

The Granatelli Motor Sports S550 Mustang Coolant Surge Tanks for all 2.3 EcoBoost, 3.7 V6, Mustang GT and Shelby GT350 are available wherever Granatelli Motor Sports products are sold.

This may be a dumb question, but how do you tell if your coolant is low?

 

Our system actually allows for an increase in fluid level. Typically, with all things being equal and normal, you should not be loosing coolant. The best way to confirm this is to simply look inside your Granatelli tank every 90 days. But again you should not be loosing coolant.

 

We just finished another batch of tanks, order yours today we are still honoring our sale prices!

 

i also wanted to add that our radiator expansion tanks won a SEMA Global Media award at the recent SEMA show:





we have a local ford dealership stocking our tanks we made with their branding:



they've hosted a few autocross events and our tanks were a hit with their customers who installed them.

if you have a logo or a name you'd like us to put on the tanks, we can do that too... so the tank will match the engine bay even more.

 

We've sold a couple more tanks, thanks to the forum and have more ready to go. I can't stress enough the ease of installation of the tanks and the benefits of having the built in catch cans.

 

To spread holiday cheer we just bumped the discount from 25% off to 30% off! Place your order today and you can receive it before Christmas.
