As horsepower increases so does the amount of heat produced. This is further compounded with the addition of a power adder. Often overlooked is the cooling system, resulting in overheating situations even when cruising. Case in point was our ProCharged New Edge Mustang. Rather than waiting on our original radiator to give up the ghost, we wanted to be proactive and enlisted the help of Mishimoto for a cooling system make over.

Factory radiators can clog over time plus have a narrower core than a performance radiator. Increasing the capacity of the core by going to a two-row design allows the radiator to hold more fluid, plus advanced construction cores increase the efficiency of the cooling.

While we didn’t option to do it at the present time, a radiator swap is great, but to fully take advantage of the increased capacity is to cool that coolant with a heavy-duty fan. We all know a buddy with two fans that are affixed to their radiator, but even then, to do it correctly, a shroud is always recommend. Mishimoto’s shroud kit can work on either their setup or onto a stock radiator assembly, which works by pulling air from the entire surface area of the radiator. When fans are connected directly to a radiator without a shroud, all the area that the fan is not covering isn’t being properly ventilated. Point being; always use a shroud, even if it’s the factory piece.

With the cooling system addressed, it’s one more piece of the puzzle for the larger plan we have for our New Edge. We need to handle a few more items before transplanting the Ford Performance 5.3L into our New Edge, but then again, half the fun is putting it all together.

1. The installation was handled by Saul Gutierrez and Tim Roberts of GEAR Driven Automotive in Northridge, California. They work on all performance vehicles but have a soft spot for Mustangs.

2. For the first order of business, Saul and Tim removed the factory coolant expansion tank and lines.

3. The factory radiator mounts have a small rubber isolator that doesn’t help a ton for vibration and is known to attribute to cracking of the stock plastic end tanks.

4. The Mishimoto radiator has provisions for the stock automatic transmission cooler lines.

5. Slick, integrated mounts bolt into the tapped bungs welded into the radiator.

6. Replacing the thermostat while the system is drained of coolant is always cheap insurance. Mishimoto’s street radiator has an opening temperature of 190 degrees Fahrenheit.

7. Currently we are running the stock electric fan but we plan to upgrade to the Mishimoto fan and shroud assembly in the near future.

8. The radiator stay kit utilizes a thicker rubber isolator to help dampen vibrations and reduce the probability of cracking the radiator end tanks. These bolt directly in place of the factory units.

9. Yes, it is as simple as that. With the radiator, fan, and thermostat installed, all we needed to do was install the coolant expansion tank and lines.

10. To finish up our install, Saul poured in Mishimoto’s synthetic Liquid Chill coolant that has an operating temperature range of -26°F to 265°F. They even state that it can help seal pin holes in the radiator! Now we can cruise the San Fernando Valley in its 100-plus degree summer weather without having to worry about overheating our ProCharged New Edge!
