OK, my water pump seems to be leaking a little out the little hold around it. leaks about a half quart a day right now but has been drivable with no other issues, I have just been topping it off with antifreeze.

I replaced the thermostat and the pressure cap on the tank earlier.

Yesterday, she all of a sudden pegged the redline on the tempo gauge. I pulled over and popped the hood, got the cap off and added coolant... she would not drop from red line. Go it home and ran cold water over the radiator and in the expansion tank and and still could not get the temp down... Temp goes down of course when it's off. so the gauge seems to be working.

Does this mean my water pump has completely failed? She was my only running car at the moment and It's left me kind of up a creek here...

What is the test to check the temp sensor? Just to see if it's reading correct. I wonder cause of not being able to get it to come down even with pouring the cold water in and around.

Thanks
