Polaris Slingshot Coolant Surge Tank by DDMWorks
The new aluminum coolant surge tank by DDMWorks is a direct replacement of the stock plastic coolant tank on your Polaris Slingshot.  The stock tanks have had a few issues with leaks and brakes, so DDMWorks solves the problem with a larger capacity, solid built tank.  The Slingshot coolant tank also has an integrated sight glass to allow the levels to be checked without removing the cap.  Don't forget to get the DDMWorks Silicone Hose Kit as now is the perfect opportunity to swap your stock hoses out.

Benefits of the DDMWorks Coolant Surge Tank for the Slingshot

  • Stronger than the brittle plastic tank, allowing for higher engine bay temperatures
  • Integrated sight glass allows you to check coolant without removing the pressure cap
  • Available in black or red
  • Larger capacity than the stock tank

Aluminum coolant surge tank
Took me about an hour to install. Had to drain the original tank, remove hoses from original tank, and install the new surge tank and hoses.

U Need This
This item not only looks great, it’s exceptionally functional. We all know that the stock coolant tank has a greater than likely chance of cracking and leaving us stuck in a place that we most likely don’t want to be. Get ahead of the game and do yourself a favor by switching out the stock part for this good looking alternative.

Red Aluminum Surge Tank
I did a complete coolant upgrade while installing DDM Works Super Charger. The item came well packaged, with everything needed and complete instructions. Would recommend to anyone. DDMWorks is #1!

Surge Tank
The Tank is well constructed. However the fit is tight for the 2018 Slingshot. It was also missing the brass plug for the port that I did not need. I had to purchase one at a lowe’s
Despite all it is a good product DM Works was very helpful

Larger and Stronger Coolant Tank
I recently noticed coolant dripping into the passenger side of my 2016 SL. After examining the custom RED Silicone Hoses...I could see that because they are a stiffer hose, there was some tension where it connected to the plastic nipple on the stock coolant tank. After reading reviews, the only option for me was the Aluminum Coolant Surge Tank...The instructions indicated not to put the bottom tank hose on until last...however I found lining up all three hoses at the same time and fitting it onto them simultaneously was the best option. There is a little wiggling that has to be done to get the final fit..but when the hoses and mounting holes were all in alignment....it popped right in and looks custom! There is a sight-glass on the side of the tank to ensure a proper fill. Highly recommend this tank over the stock plastic.
