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.
