How far can you drive without a serpentine belt?

I know this is a dumb question but I am asking it. Can you drive 1.7 miles on a flat surface without a serpentine belt on a 1994 ZJ with the 4.0L if the engine is cool from the start? Will the engine over heat that fast being that there is no coolant pump or fan running? Also do you have oil pressure if you have no belt?

I'm gonna go with....no. Where are you trying to go and why don't you just replace the belt where it is now?

The belt is fine. The thing is I am stripeing down my Jeep. I need the two aftermarket alternators in the Jeep. The problem is they take a long time to take out and I dont want to do it in the -10 degree cold. So my shop is 1.7 miles from my house. Well the Jeep is not going to be driven untill summer so I dont need to put a new belt on tell summer. It would make things 10x easier if I could just drive it home without a belt because I dont have a AC compressor anymore and thus I have to pretty much randomly guess as to the new belt size and that will take many trips back and fourth to the automotive parts store. But if it cant be done I will just pull the alts at home I guess then.

Well it might be possible. I did this with a friends xj. The motor was already blown and the belt was gone. But other than the harder than hell steering and some other minor difficulties it was done. It was dark out too and couldn't use the lights because it would drain the battery to quick.

Steering will be difficult...overheating may be possible if it gets much above 10 deg I bet...battery will be drained pretty quickly...

I drove about 4 miles without mine a couple weeks ago. The AC idler pulley locked up and broke the belt. So I pulled over let it cool down (at Taco Bell) then fired it back up. Pulled out on the road, got up to speed, shut it off, coasted to the red light, repeated till I got home. I live in Florida and it wasn't -10. Just keep a close watch on the temp gauge.

Well does the oil pump still run? I was not sure of the water pump pully also ran the oil pump. Because without oil the thing wouldent last 3 min.

Oil pump is not driven off a belt. Its driven off a gear.

You'll overheat within a minute or so without the water pump spinning.

Of course you can make it. Just be smart about it. Watch your temp gage. Stop the engine if necessary. Dress warm! Have a friend follow you!!!

I agree with Steve, no problem as you'll only be driving maybe 2 minutes most. If it's dark and battery is good, you'll have lights also for that time, but as they have said, no power steering.

Oops forgot about the PS. Yea I having me jeep a short distance without the PS. It is a huge choir to make turns at low speeds! I would call it dangerous. Thanks for pointing that out Turbonut.

oh this is definately possible. i was coming home one morning at 4:30 in the am in my mustang hatch 5.0 and the belt broke. I didn't know at first and went to turn a corner and the steering was out of control, and the alt light came on. Looked down at the temp and it was slowly starting to climb. Sure enough no belt and about 4 miles from the house! I let the car cool down to a cooler degree, then drove home without a problem.

That's a little exagerated. My dad lost the belt on his old F150 and drove it for another 10 min to the nearest exit off the highway without overheating it.....and it was already up to temp.
