What can happen to water pumps after 5 yrs or so? Mine gets hot pretty quick now it seems, doesn't take as long in stop and go traffic to switch the fan on as it used to. Comes on just past the half way mark. It was only about 26C out and in heavy traffic, after a couple stops, even the red temp light came on after starting back up.
I thought either the t-stat is sticky or the water pump is weak, if possible.
Thanks.
