It is much easier to do it this way and you will have a lot more room to insert the plastic cover caps in-between the condenser and the radiator than between the condenser and the grill. My personal recommendation is to insert the 4 zip ties through the cooler and the condenser from the grill side in towards the motor. They are very fragile and will bend easily.ĩ. You can slide it in from the top or bottom, it really doesn’t matter – just be very careful not to bend or damage the fins on the cooler or on the car’s radiator. Then carefully slide the cooler in place in front of the A/C condenser. It was also helpful in aligning the 4 holes where the zip ties would pass through the A/C condenser.Ĩ.The next step is to take each 4-foot piece of transmission hose and secure it with the clamps provided to the cooler. The purpose of this was simply so I could line everything up and get an idea of how things were going to fit, how the hoses would hang and where, etc., before committing. You need to be able to tilt the radiator back so there is room to work.ħ.I traced out a template for the cooler on a piece of plain folder paper. Casualty of tinkering with your car.Ħ.Remove the two nuts which hold the radiator to the car frame. I sacrificed the pop-on clip when I removed it. The undercover is held in place with 7 bolts and one pop-on clip. The two pictures below show the location of the transmission fluid lines before installation.ĥ.It is necessary to remove the Driver’s Side Engine Undercover to expose the transmission fluid return line. On the Maxima this is the upper line (without the “banjo” bolt). To do this you have to locate the fluid return line. For optimal cooling effect the auxiliary transmission cooler should be mounted in front of the A/C condenser.Ĥ.The cooler should be installed in “series” with the stock tranny cooler. Ask specifically for transmission fluid hose!ģ.The picture below shows the A/C condenser before installation of the cooler. When you get the extra hose, DO NOT get fuel line, it is not the same. The 4 feet of hose that comes with the cooler is not enough, since you will have to replace the stock transmission return line entirely. I bought an extra 4 feet of transmission cooler hose (not pictured) to use as the return line back to the transmission. In fact, the 403 would probably have been easier, as it is the same height, but 2.5 inches shorter.Ģ.Here is everything that came in the kit. I would not recommend getting a cooler any larger than the 404, as it will be too big and difficult to install. It is supposed to lower your transmission fluid temperature by 70 degrees Farenheit. The 404 is considered “Heavy Duty” and is 7.5 inches tall by 15.5 inches wide, by 0.75 inches thick. There were other smaller models, but I figured I would get the largest one practical. 1.I bought the Hayden model 404 from Pep Boys for $49.99 plus tax.
