Water pump driven by the accessory belt?

[ls1ac]

I would like to keep stirring, and ask the OP what older cars had a direct crank driven water pump that worked with out a belt.

Apparently I did not express myself very well. By driven by crank, I mean timing belt. If water pump is driven by t-belt and t-belt breaks, suppose engine is non-interference, everything stops. No danger of overheat.

If it is driven by accessory belt, there seems to be this weird possibility that an engine can work itself to death. I think this is what I was trying to ask. Just some clarification.

99% of the half-decent engine designs out there puts the alternator and the water pump on the same belt.

So unless you are a truly ignorant driver to the various lights that will come on after the alternator stops charging, the chances of you blowing up the engine from a belt failure + overheat is next to none.

For fear of inflaming this thread any further, I will comment on the original question.

Yes, there is a sensor and a mechanism ....... the sensor is called a temperature gauge and the mechanism is the driver shutting down the engine.

Now, who wants to debate that ......

That is not good enough. A lot of people would keep driving it till home to avoid a tow truck. They might get lucky on some other stuff, but not this one. Of course, they have no clue.

Oh, I'm glad you said 99% ........

My grandfather's older Ford Model T, was a fine machine ....... and it didn't have a water pump or an alternator ......

I remember well that my grandfather would put me "behind the wheel" when I was about 3-4 years old (to keep me out of the way, no doubt), and I would "drive" for hours (never leaving the barn) ........ oh, the questions I would have ..... what does this do ...... how does this work ....... why ........

Most car owners fall into this category. What saves the unwashed masses is that modern accessory belts can last practically the life of the car.

Usually something else pukes before the belt.

Maybe those folks would have benefitted from a temperature gauge like this as a constant reminder .......

Then those people deserve to be stranded on the side of the road.

Temperature gauges are going the way of the dodo. My wife's mazda only has a light for when the temp is low and a light for high temp. Most likely won't even notice the temp light came on. Hell her tire pressure was low and the car beeps when a warning light comes on. We both looked at the cluster for 30-45 seconds before we found the light. So much other stuff on the cluster that warning lights just blend in.

Seems like we are moving further from the idea that people are capable of monitoring their own vehicles. You won't have to see a light or figure out what it means. The car will just speak to you, set up a service appointment, drive itself to the appointment if it can or call a tow truck itself. Then you will get a service bill in the mail and just won't care what was actually wrong. Its fixed now and you didn't have to lift a finger. Not looking forward to this. Hopefully not in my lifetime.

True, except for the bolded part. The service cost will just be direct deducted from your checking account .......
