car myth busters

None of it was news to me.

The one about flushing coolant with oil changes? Seriously? Never heard that myth. I can count on 2 fingers how many times I've flushed coolant in a vehicle, and both times were due to a water pump being changed out.

Guess what! If you had changed the coolant, chances are high that you would not have had to change the water pump.

1st water pump was on a 78 T-Bird, original water pump, more than 200K miles on it done in 1997. It was pissing out coolant through the weep-hole one day.

2nd water pump was changed since the mechanic had to remove it to change the timing belt, which was preventative maintenance on a 120K 97 ranger, this past winter. One of those, since you're doing this, you mind putting on a new one? I did the same with the thermostat and hoses. Did it need it - no...

OK, I just remembered that i had the coolant flushed in my 97 ranger when I bought it, 50K miles, in 2001.

That would be true for older cars, especially domestic ones. However, a water pump will not last for ever.
