Hayden 679 Specs

The Hayden 679 utilizes an 11 5/8″ x 11 3/4″ x 3/4″ design that is not only large enough to efficiency cool transmission fluid, but is still thin enough to mount in most common locations without much modifications. 

In addition, the Hayden 679 offers a GVW rating of up to 30,000 pounds which provides the ability to help tow up to 10,000 pounds (if your vehicle is rated to do so).  Its 30,000 GVW rating makes it a great cooler for class A mobile homes, and allows you to use large travel trailers, and 5th wheel trailers. 

For the cost, the Hayden packs a mighty punch in terms of capabilities.  Not only is it not too large where it can cause mounting issues, but it has the ability to help tow more than enough for more common applications.  

Hayden 679 Installation

Since the Hayden 679 comes as a universal kit, installation will depend on where you need to install it and any extra parts you may need.  The kit comes with extra transmission hose, mounting brackets with nuts and bolts, various barb fittings, hose clamps, spacers and mounting ties. 

Since most people will opt to mount the transmission cooler in front of the air conditioning condenser and  radiator, the mounting pieces will be enough for most installs.  The biggest question mark lies with the lines and fittings.  Since this cooler utilizes barb fittings, it is best to use simple rubber lines rather than AN lines.  

Despite its size, it is recommended to run this cooler in addition to the stock cooler in the radiator. While this may be large enough to use as a stand alone cooler, the best use would be to use this so the fluid runs through the cooler after the radiator.  

What We Like About The Hayden 679:

  • Easy to install – The thinner body design makes installation easier then other coolers with the same capacity
  • High GVWR capacity (30,000) and reasonable towing capacity (10,000)
  • Rigid plate and fin style construction
  • Comes as a complete transmission cooler kit for quick installation

What we don’t like About The Hayden 679:

  • You may have to get creative with some additional parts to mount it on some vehicles
  • Only utilizes barb fittings – While this isn’t bad, it’s something that users would need to keep an eye on over time to make sure hoses stay in place and don’t leak

Conclusion

Between its high GVW rating, efficient plate and fin style design, and affordability, the Hayden Automotive 679 transmission cooler is by far one of the best transmission coolers available.  The 30,000 GVW allows for ample trans cooling in most common applications and it’s price certainly is friendly on your wallet. 

Another great benefit the Hayden 679 offers is that it comes with a complete installation kit with extra transmission hose, clamps, and everything else needed for an easy installation.  While the kit comes with various fittings, it might be necessary to purchase additional fittings, depending on how you plan to route the fluid lines.

Overall, it is hard to beat this cooler, and For the budget minded driver with above average cooling needs, the Hayden 679 certainly fits the bill.
