I have a dodge ram 1500 w/360.Bout a year ago the waterpump went out so i replaced it and had to have the heads and all done.still overheating so replaced thermostat.still running high. about a week ago started leaking under the waterpump again.Checked all hoses then replaced waterpump again.It ran fine going to store and then to work and checked level and it was full no leaking. Drove home and water is pouring out of weepy hole! but temp never got above 220.I'm lost and broke! Help!

 

welcome to df...

sounds like you have/had an air bubble in your cooling system... if your new pump is under warranty, get a new one, before you do I'd flush the motor real good and make sure there is no gunk coming out of it. when you refill it, use distilled water with the antifreeze. this prevents any kind of sludge from forming.
