Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
No circulation.
If a water pump is bad they usually leak coolant
my engine runs hot on my 2000 dodge caravan how can i tell if its the water pump i already change the thermostat does not help
There is a small hole in the bottom that is designed to leak when the water pump bearing is goin out
if you are talking about the weep hole in the water pump. that hole will let water out when the seals in the water go bad. that will tell you to get the water pump replaced.
do a coolant pressure test.
IF you stay on it full time, it takes 2-1/2 hours. Don,t let any shop tell you different Hope this helps
