Homemade Electric Buggy, Ep 7: Cooling System

Homemade Electric Buggy, Ep 7: Cooling System

In this video I install the cooling system for the electric motor in my homemade electric buggy. As some of you know, the battery is sized large enough to only require forced air cooling, but the motor requires liquid cooling (a glycol/water solution). To do that, I'm using an 8x12" radiator with a 12V, 7" fan from Derale Performance. The glycol solution will be circulated by a Flojet 12V general purpose pump with a flow rate up to 10 L/m. I made a reservoir/overflow container from 3" ABS pipe, an end cap for the bottom, a screw cap for the top and barbed fittings for connecting the heater hoses. I also incorporated a filter between the reservoir and pump to keep particulates out of the system. Links for all of the parts that I used can be found below with the exception of the ABS pipe and fittings and heater hoses. You can source those at a local home building supply store like Home Depot. Electricmotorsport.com also sells a complete kit with the pump, filter and radiator together to make things simple, but for a slightly higher price.
