<VV> Warning buzzer or flashing light for broken Fan belts?

Tue Jul 24 12:29:38 EDT 2018

I have a convertible too, and it's impossible to see any lights on the dash
or the LED readout of the stereo etc :>~{~!

So, that's exactly what I need, a buzzer or a siren! - where did you get
that, and how did you hook it up?

Thanks for the info!

I have a Corsa turbo vert and in sunlight with the top down, you absolutely
cannot see one of those wimpy warning lights.  My solution was to hook up
one of those annoying piezo buzzers so that it will sound off if I toss a
belt OR loose oil pressure.  It's a belt and suspenders solution.

Hi guys ~

My first fan belt issue in quite a while ...

I have a Corsa dash ion a Monza and no ID10T light, so I ran an LED off the
alternator output, which would (and did) go out if the she tosses a belt.

I had driven her about 240 miles yesterday at freeway speeds and she was
doing fine.

Last night, I thought the engine was running even smoother than normal, and
before I noticed the light was off, I thought maybe it was because the fan
belt broke so, looking at the light, it was off, and I pulled over to check
it.

Sure enough - the belt was torn up. 

The engine knocked for about 5 -10 seconds (which it never does otherwise)
and I changed it in the dark.

I don't know how hot she got, but is there a correlation between the time it
knocks and damage done?

I was about 100 miles from home at night, and she started fine and behaved
OK at 70 MPH for the trip home.

I want to get a warning buzzer or flashing light so I notice sooner next
time, any suggestions?

There is no record of Chevy testing the 140 engine for temperature.  The
140 heads have 27% less fin area then the other heads due to the larger
intake and exhaust ports.  It stands to reason than they would run
hotter.then the average engine but I suppect they would not overheat in
normal operation.
