Driving 4 miles with no water pump belt

Would it do any harm to drive 4 miles to my mechanic's garage with the water pump belt broken? Is there a risk of the engine overheating in such a short period of time if the engine is started from cold and I leave immediately?

Hard to say.

The issue is you will have localized heating that does not show on the gauge.

I agree...

Or you might use the cash saved from not using a tow truck to pay your mechanic to make a house-call.

If it doesn't fit, force it.
If it breaks, it needed replacing anyhow.

$75 for a tow to the mechanic against $7500 for a rebuilt engine....

I'm thinking I'd have it towed.

(And before the rest of y'all chime in, do you really think he's going to be swapping the engine himself if he can't/doesn't want to DIY a fan belt?)


When I die, I want to go quietly in my sleep, like Grandpa.
Not screaming, like the people in his car.

Sorry - my car is a 1973 450 SLC and I live in central Indiana.

I realize that replacing a belt is not a big deal to many on this forum - and really isn't for me either if I had the motivation and time to dig into it myself - but one of my concerns is that I order / install the correct belts. This car is a very early '73 and I believe that some common parts for this car do not even have the same part numbers as some later cars of the same model year (I found that out when I had to replace the fuel gauge sender).

For such a simple job I'd rather have my local, independent M-B shop, who knows what parts to use from the beginning, get the job done right the first time than discover I bought and mounted the wrong belts and have to redo the job.

For what it's worth, my mechanic said a 4-mile drive from a stone cold engine start probably would not hurt the engine, plus the water pump belt is a dual design and there is still one remaining belt driving the pump. The other belt on the dual pulley is slipping / burning badly and making a hell of a noise so I was just going to cut it off to drive it into the shop.

A single belt, at correct tension, should drive the pump with no problems. They may have been loose to start with, or the pump bearing could be sketchy.

If you gotta drive it, leave the belt.





For as long as it lasts...........

It would get hot fast with no pump. I would be afraid.

Timing has a lot to do with the outcome of a Rain dance.
