Changed water pump, now car overheats?

the car ran fine before i changed the pump, it just leaked coolant due to a seal in the water pump, so i changed the water pump, and now my coolant light is on, but i refilled the coolant, and when i drive it for about a mile it overheats and the coolant starts %26quot;boiling%26quot; out of the over flow....



the upper radiator hose seemed warm, but i have not replaced the thermostat....

what could be wrong?

sounds like u just need to burp the system(air pocket in the coolant system) ,run the car with the rad. cap off till it reaches normal running temp.and the t-stat opens watch for the coolant to circulate in the rad,it may be possible that the t-stat got stuck in the close position,and also check that ur cooling fans are coming on.

A great big air bubble in the system or the wrong water pump
check your fan motor, fan relay,fan fuse, also use the air bleeder valve to bleed the air out of your system autozone.com has a componet locator,repair manual, and a trouble shooting guide to help you
an air bubble and its probable a good idea to change the thermostat when you change a water pump u should change the thermostat just to be safe that and it probably hasent been changed for a long time so chang it i work in a shop. but you are your own person so do what you think you should ok
