Homemade Electric Buggy, Ep 7: Cooling System

In this video I install the cooling system for the electric crosskart/buggy ME1616 motor. As some of you know, the battery is sized large enough for the motor 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.

I have really enjoyed following along on this build. Something to consider on the coolant tank mount, this may be overkill, but covering the edges of the aluminum where it contacts the tank with some split vacuum hose would prevent the aluminum from digging into the plastic over time. I learned this lesson the hard way.

Thats going to be such a great vehicle, and you're going to have a blast riding it

cannot wait to see the numbers, i haven't seen a water cooled electric motor before.

Its clear to me that you have thought through the issues, however what astounds me is the out of the box solutions you come up with. Very impressive James.

Mr. Biggar, you make it look simple. Nice!

That metal bending rig is amazing.

that's impressing iam so excited to see this crosskart working

What an awesome looking vehicle is shaping up!

Amazing build !

Good share, Thank you for introducing You have good skill.

Excellent project, I would like to see this great machine in action, I hope to see the videos of the tests soon off-road. Ah, and a question, ¿how does the vibration of the entire chassis caused by the road imperfections affect the batteries?

looking forward to the result...

Looks good 👍

This is your hobby or business Love from India 🇮🇳 ♥
