I think we have used 2 in about 10 years.
How tight do you have the belt? It can be pretty loose.

I burned one up 2 years ago, it was probably 5 or 6 years old. The one it replaced is used as my spare, it was used for probably 5 years.

If the belt is too tight, it will burn them up in a hurry. My belt is really loose. Since the belt is a cog drvie, it doesnt need to be tight. Just tight enough to keep it from falling off.

I made my own electric water pump drive for my FE back in the late 70`s, & the first motor was a heater fan motor from one of my 57 Fords. It lasted until about 8 years ago. Then I borrowed a motor from a 74 Ford pickup, which lasted 4 more years. I then bought a new motor, for a 78 Econoline heater, (which is identical to what Moroso uses, right down to the orange & black wires )and its still working. As noted, a tight belt really hurts them. I run my belt very loose, just enough so it won`t fall off.

Mike r,
I've seen some of the electric drive motors with and some without two dime-size holes in the motor housing...I believe the holes help in promoting cooling air to circulate in & out of the motor better than a fully enclosed housing. We all know heat will kill an electric motor.

I recall when I first was installing mine, I noticed the holes in mine. I started to worry that the holes may allow water to collect during trailering the car to & fro in the rain, so I was about to simply wrap the black housing with a few wraps of black electrical tape and call it 'smart'....but then I thought about them possibly being vent holes, so I decided I'd just ensure that it's had time to dry before running it rather than plug off the "vent holes"........

If you don't have such housing vent holes, you may want to look into obtaining a motor with them or possibly (& carefully) drilling two holes in your motor housing to make your own vent holes.

Just my 2 cents,
Ryan

I think that the hole in the motors housing is simply there because some of the Ford heater fan motors had a rubber elbow running from the motor to the heater box. It appears that all the newer Moroso WP drive kits use the motor with the hole in it.
